For any work on the equipment, which extends above and beyond the operation of the regulating system, the details provided in the supplementary documents must be observed, particularly with regard to safety instructions.

Documentation

The technical documentation included in the scope of supply is a constituent part of the equipment. It must be stored in such a way that it can be consulted at any time by the operator or technicians.

2 Product description

INFORMATION

The RoCon+ HP controller is part of the Daikin Altherma EHS(X/H).

It consists of the RoCon BM2C switching panel PCB, to which actuators and sensors as well as other components of the control system are connected and the control panel RoCon+ B1.

In this instruction manual we only explain the functions and setting possibilities of the control unit. More information on the boiler control panel and other equipment components can be found in the supplementary documents.

The electronic, digital control unit is able to automatically control all heating and hot water functions for a direct heating circuit, a storage loading circuit and also further heating circuits via optionally connectible mixer modules, depending on the heating device.

It undertakes all safety management for the Daikin Altherma EHS(X/H). In the event of a water shortage or undefined operating states, this executes a . A corresponding error message shows the operator all the information regarding fault causes.

All function settings for the Daikin Altherma EHS(X/H) and the optional RoCon devices that are connected via the data bus are undertaken with the controls of the integrated RoCon+ B1 control panel and shown on the plain text display with coloured backlighting.

The following additional, optional devices can be connected to the Daikin Altherma EHS(X/H) via the controller data bus:

- Room controller EHS157034

- EHS157068 mixer module

In addition, the RoCon+ HP controller has a frost protection function for the direct heating circuit and the storage tank charging circuit as well as an automatic function for heating support (integration of an additional heat source such as a wood-burning boiler or solar system).

The potential-free AUX switching contact can be used to carry out different control functions in conjunction with external devices (request from an external heat generator, switching to bivalent operating mode, external status display, etc.).

In addition, it also has several inputs for assessing external control contacts (external operating mode switching or heat request, Smart Grid and low rate EVU functions ^(1) .

The optional outside temperature sensor installed on the north side of the building can be used to further optimise the weather-compensated feed temperature control.

If the optional EHS157056 gateway is installed and connected to the Internet, the Daikin Altherma EHS(X/H) can be conveniently monitored and operated by remote control using a mobile phone (app).

The RoCon+ HP control unit contains a timer that can be used to set:

- 2 individually-adjustable timer programs (2) for room heating and cooling (direct HC),

- 2 individually-adjustable timer programs for domestic hot water preparation,

- 1 individually-adjustable timer program for an optional circulation pump.

Initial commissioning of the heating system is described in the installation instructions for the Daikin Altherma EHS(X/H).

Certain menu items of the RoCon+ HP control unit are only accessible to the heating expert. This security measure ensures that no undesirable malfunctions arise during operation of the system through incorrect settings.

All settings for the allocated HC can be carried out in the same way as the operating unit. If the terminal function is activated, all operating possibilities that are available on the integrated operating unit are available, with the exception of certain special functions (e.g. manual operation).

After corresponding assignment, a connected EHS157068 mixer module is also operated using the RoCon+ B1 control panel and/or the EHS157034 room station.

3 Operation

3.1 General

DANGER: RISK OF ELECTROCUTION

If electrical components come into contact with water, this can cause an electric shock as well as cause potentially fatal burns or injuries.

• The displays and keys of the control unit must be protected against the effects of moisture.
• To clean the control unit, use a dry cotton cloth. The use of aggressive cleaning agents and other fluids can cause damage to devices or lead to an electric shock.

INFORMATION

The Daikin Altherma EHS(X/H) makes the most effective use of energy at the lowest possible return and hot water temperature setpoints.

If an external heat generator (e.g. the optional backup heater) is activated at feed temperature setpoints above 50 °C, the efficiency (COP) of the Daikin Altherma EHS(X/H) can deteriorate (depending on the external temperature).

An optional gateway (EHS157056) can be used to connect the control unit RoCon+ HP to the Internet. This enables remote control of the RoCon+ HP by mobile phones (by app).

Operation via the room station

It can also be operated via the optional EHS157034 room controller. For this purpose, observe the operating instructions enclosed with the device.

4 Function

The system fully automatically controls the operation of the room heating, room cooling and domestic hot water generation on the sanitary side on the basis of the specifications set in the RoCon+ HP control system. The functions that can influence system operation are described below.

Some of the functions and parameters described are restricted by access privileges and can only be set by a heating specialist (see Chap. 4.5.1).

4.1 Mode

[→ Main menu → Operating mode]

This menu is used to select the operating mode for operating the device. The current operating mode is indicated by a corresponding symbol on the start screen.

Standby operating mode

NOTICE

A heating system that is not protected against frost can freeze in the event of frost and thus be damaged.

• Drain the heating system on the water side if there is a danger of frost.
• If the heating system is not drained, the power supply must be ensured and the mains switch must remain switched on if there is a risk of frost.

In this mode, the Daikin Altherma EHS(X/H) is switched to standby mode. The frost protection function remains unchanged. In order to maintain this function, the system may not be disconnected from the mains.

All controllers integrated in the RoCon system via the CAN bus are primarily also switched to the "Standby" operating mode.

INFORMATION

In the [Standby] mode, the heat pump and the optionally connected backup heater are disconnected from the power supply (energy-saving mode) if the following conditions are met:

• the external temperature sensor is connected and correctly parametrised in the system configuration,
• the external temperature is more than 8 °C
• there is no heating requirement,
• the frost protection function is not active in any connected HC and
• the Daikin Altherma EHS(X/H) has been switched on for at least 5 minutes.

ModeReducing

Reduced heating operation (lower room setpoint temperature) according to the set reduction temperature in the [Room temperature reduced] parameter (see Chap. 4.2).

Domestic hot water generation according to the temperature set-points and switching cycles in the [Hot water automatic 1] hot water time program (see Chap. 4.2).

ModeHeating

Heating, cooling mode according to the room temperature setpoint set in the [Room temperature setpoint 1] parameter (see Chap. 4.2).

A connected external temperature sensor (weather-dependent feed temperature control unit) or a connected room control unit also influence the temperature setpoint.

Domestic hot water generation according to the feed temperature setpoints and switching cycles in the [Hot water automatic 1] hot water time program (see Chap. 4.2).

ModeSummer

Only domestic hot water is generated according to the set temperature setpoints and switching cycles in the [Hot water automatic 1] hot water time program (see Chap. 4.2).

All controllers integrated in the RoCon system via the CAN bus are also switched to the higher-level [Summer] mode.

Mode Automatic 1 (time program)

Automatic heating and setback mode according to the permanent time programs (see Chap. 4.3):

• [Heating circuit automatic 1]
• [Hot water automatic 1]

Mode Automatic 2 (time program)

Automatic heating and setback mode according to the permanent time programs (see Chap. 4.3):

• [Heating circuit automatic 2]
• [Hot water automatic 2]

INFORMATIONSWITCHING CONTACT FOR EXTERNAL OPERATING MODE CHANGEOVER

Switching can also be performed from an external device (e.g. modem, ...) via a floating switching contact connected to terminal J8 of the Daikin Altherma EHS(X/H) to the "Ext" terminals. See Tab. 4-1.

In this case, the switching contact functionality is dependent on the parameter [Func. burner blocking contact]:

• [Func. burner blocking contact] = Resistance values (default setting): Evaluation of the resistance values.
• [Func. burner blocking contact] = Burner blocking contact: Evaluation as a burner blocking contact. If the switching contact is closed, the external heat generator has priority.

Mode Resistance Tolerance
Standby < 680 Ω ±5%
Heating 1200 Ω
Reducing 1800 Ω
Summer 2700 Ω
Automatic 2 4700 Ω
Automatic 2 8200 Ω

Tab. 4-1 Resistance values for evaluating the EXT signal

INFORMATION

The resistances specified in Tab. 4-1 function in a tolerance field of 5% . Resistances outside this tolerance field are interpreted as an open input. The heat generator switches back to the previously active operating mode.

The input is not considered for resistance values greater than the value for "Automatic 2".

If several switching contacts are connected to the Daikin Altherma EHS(X/H) (e.g. smart grid, room thermostat), the associated functions may have a higher priority than the external mode switching. The mode requested by the EXT switching contact is then possibly not activated or is only activated later.

Besides these operating modes, different temporary time programs (see Tab. 4-2) are available that are carried out with priority after activation.

4.4.2 System

[→ Main menu → Settings → System]

This menu combines basic parameters of the heating system.

Further explanations and possible settings for this menu can be found in Chap. 7.5.2.

4.4.3 Additional heat generators

[→ Main menu → Settings → Ext. source]

This menu can be used to configure the integration of an optional external heat source.

The heat supplied by an alternative WEZ must be fed to the unpressurised storage tank water in the Daikin Altherma EHS(X/H) hot water storage tank.

• When using the optional BUxx backup heater, this is carried out due to the design installation situation.
• If an alternative WEZ (e.g. gas- or oil-fired boiler) is used, this can be hydraulically integrated
• unpressurised via the connections (solar feed and solar return) of the hot water storage tank or
• in the case of Daikin Altherma EHS(X/H) ...B device types, via the integrated pressurised solar system heat exchanger

The setting of the [Config. of external heat source] parameter is used to define if any additional heat generator (WEZ) is available for domestic hot water preparation and heating support, and which.

• No external heat source
• Optional backup heater
• Ext. heat sources HW and HZU: Alternative WEZ provide domestic hot water preparation and backup heating. To request the WEZ, relay K3 on printed circuit board RTX-EHS is switched.
• Ext. heat source HW or HZU: Alternative WEZ 1 (optional BUxx backup heater) undertakes domestic hot water preparation and alternative WEZ 2 undertakes heating support. To request WEZ 1, relay K3, and to request WEZ 2, relay K1, on printed circuit board RTX-EHS is switched respectively. Heed warning notice! The operation of an additional alternative WEZ is also influenced by the settings of the [Bivalence function] and [Bivalence temperature] parameters.

Further explanations and possible settings for this menu can be found in Chap. 7.5.3.

4.4.4 Inputs/Outputs

[→ Main menu → Settings → Inputs/Outputs]

This menu can be used to adjust parameter for inputs and outputs of the controller PCB to optimise the system controller individually.

Smart grid

WARNING

There is a danger of scalds at hot water target temperatures over 65 °C. This is possible because the utility company (EVU) is entitled to control current draw optimised according to supply and demand in the definitions for Smart Grid.

Due to such forced charging, the hot water target temperature in the hot water storage tank can exceed 65 °C.

This storage tank charging is carried out even when the [Standby] operating mode is set.

- Install scald protection in the hot water distribution line.

To use this function, a special electricity meter with SG receiver to which the Daikin Altherma EHS(X/H) must be connected is required.

As soon as the function is activated by the [Smart grid] parameter, the heat pump is set to an operating mode as per Tab. 4-4 depending on the utility company signal.

Signal(3)		Electricity costs	Effect on
EVU SG Domestic hot			water	Heating installations
1 0 --- No operation			(4)	No operation(4)
0 0 Normal Normal operation			tion	Normal operation
0 1 Low Switch-on re-			commendation and storage tank temperature setpoint is increased depending on the [Mode Smart Grid] parameter.	Switch-on recommendation and flow temperature setpoint are increased depending on the [Mode Smart Grid] parameter.
1 1 Very low Switch-on com-			mand and storage tank temperature setpoint is set to 70 °C.	Switch-on command for storage tank charging.

Tab. 4-4 Use of the SG signal

AUX switching function

Setting the [AUX switching function] parameter selects the switching conditions for the potential-free AUX switching contact (toggle switch output A). This switching contact can be used to control an external heat generator, for example.

If one of the switching conditions is fulfilled, the potential-free switching contact is switched after the time set in the [AUX delay time] parameter.

AUX switching contact (toggle switch output A) is not switched if setting is deactivated.

AUX switching contact (toggle switch output A) is switched, if setting

- Storage tank temperature ( T_dhw ) ≥ [TDHW switching threshold] parameter value.

• if an error is pending.
• Outside temperature < [Equilibrium Temp] parameter value.
• Heat request for domestic hot water preparation.
• Heat request for room heating.
• Heat request for room heating or domestic hot water preparation.

Interlink function

Setting the [Interlink function] parameter = On offers the possibility that the Daikin Altherma EHS(X/H) two different feed temperature setpoints are included in the control.

This applies to both weather-compensated control and control according to a fixed feed target temperature (see Chap. 4.5).

One possible application is, for example, the additional integration of an HP convector in a surface heating and cooling system.

Prerequisite: 2 switching contacts are connected to Daikin Altherma EHS(X/H) plug connection J16 (e.g. room thermostats).

- [Interlink function] parameter = Off: Deactivated

- [Interlink function] parameter = On: Evaluation of the heating and cooling switching contacts at plug connection J16 on the RoCon BM2C PCB. Activation of cooling mode only by switching the operating mode to [Cooling] (see Chap. 4.1). Setting of the [Room thermostat] parameter is no longer evaluated.

- Open switching contacts: Only frost protection active

- [Heating] or [Automatic 1] / [Automatic 2] operating mode active during daytime switching cycles.

- Closed switching contact Heating = IL1

- It is controlled to the normal feed target temperature according to the parameter settings for [Heating].

- Closed switching contact Cooling = IL2

- It is controlled to the increased feed target temperature (normal feed target temperature + value of the [Interlink temperature rise] parameter). Priority if both switching contacts are closed!

- [Cooling] operating mode active.

- Closed switching contact Heating = IL1

- It is controlled to the normal feed target temperature according to the parameter settings in level [HC Configuration] > [Cooling].

- Closed switching contact Cooling = IL2

- The system is regulated to the reduced feed target temperature (normal feed target temperature - value of the parameter [Interlink temperature reduction]. Priority if both switching contacts are closed!

Further explanations and possible settings for this menu can be found in Chap. 7.5.

4.4.5 Intelligent storage tank management

[→ Main menu → Settings → ISM]

If the storage temperatures are high enough, the energy in the storage tank can be used for room heating. This can either increase comfort ([Continuous heating] function) or make it possible to use energy from an external heat source, e.g. solar, when heating is required ([Heating support (HZU)] function).

Continuous heating

This function enables uninterrupted heating, even when the evaporator is being defrosted. This enables high comfort to be guaranteed, even with rapidly reacting heating systems (e.g. convectors).

Heating support (HZU)

If the Heating support function (parameter [Heating support (HZU)] = On) is activated, the energy in the Daikin Altherma EHS(X/H)'s integrated storage tank is used to undertake the heating function. If the storage temperature is sufficiently high, the burner remains inactive.

The minimum value (T_HZUmin) is calculated as follows: T_HZUmin = currently active hot water target temperature [Hot water temperature setpoint] + [HZU hysteresis] parameter.

Switch-on condition:

Tdhw > T_HZUmin + 4 K and Tdhw > [Hot water temperature setpoint] information parameter + 1 K

If the switch-on condition is fulfilled, heat is taken from the storage tank and this is used to supply the heating system.

Switch-off condition:

Tdhw < T _HZUmin or Tdhw < [Feed temperature setpoint] parameter (see Chap. 4.5.3)

If the switch-off condition is fulfilled, the heating support from the hot water storage tank is set and the burner takes over the heating operation.

The [Power BIV] parameter limits the maximum power that can be taken. The [HZU max. temperature] parameter limits the maximum temperature that can enter the heating system.

Further explanations and possible settings for the parameters in this menu can be found in Chap. 7.5.5.

4.4.6 Special functions

[→ Main menu → Settings → Special]

Special functions influence the power consumption of the heat pump. For example, quiet mode means that the heat pump outdoor unit operates at reduced output. This reduces the operating noise generated by the heat pump outdoor unit.

Quiet mode

CAUTION

During active quiet mode, the output in room heating and room cooling mode decreases so that it may no longer be possible to achieve pre-set target temperature values.

- If outside temperatures are below freezing, there is a risk of material damage caused by frost.

When the function is activated, the heat pump operates in low-noise mode. The [Noise level] parameter can be used to select three noise levels.

Further explanations and possible settings for this menu can be found in Chap. 7.5.

4.5 Configuration

[→ Main menu → Configuration]

This menu can be used to optimally adapt the operating characteristics of the system to the system structure and the needs of the users. Additional programs facilitate commissioning. Depending on the access authorisation (user or expert), different parameters are available.

Further explanations and possible settings for the parameters in this menu can be found in Chap. 7.6.1.

4.5.3 HC configuration

[→ Main menu → Configuration → HC config]

This menu is used to adjust the basic functionality of the heating circuit.

Further explanations and possible settings for the parameters in this menu can be found in Chap. 7.6.2.

Weather-dependent feed temperature control

If the weather-dependent feed temperature control is active, the feed temperature ([Feed temperature setpoint] parameter) is determined automatically depending on the external temperature according to the set heating/cooling curve.

This function is activated in delivery condition. It can only be deactivated (fixed value control) or reactivated with a technician code.

If the room controller is also connected (EHS157034) to the RoCon+HP, the temperature setpoints are controlled according to the weather and room temperature ([Room Influence] parameter).

This function can only be configured using the technician code. Contact your heating expert in this regard.

This function is activated or deactivated via the [Weather-dependent] parameter in the "Configuration" menu.

- [Weather-dependent] parameter = Weather-compensated: Weather-compensated feed temperature control

- [Weather-dependent] parameter = Feed temperature, fixed: Control based on fixed target temperature

- For heating mode: [Feed temperature heating mode] parameter or [Feed temperature reducing mode] parameter

- For cooling mode: [Feed temperature cooling mode] parameter

INFORMATION

The weather-compensated feed temperature control has no influence on the feed target temperature in the case of a hot water circuit request.

With connected Mixer module

The setting of the heating/cooling curves and the activation of the weather-compensated feed temperature control for the assigned HC are carried out in the same way as described above.

The assigned HC can be operated as a:

- Mixer add-on

The outside temperature of the outside temperature sensor connected to the Daikin Altherma EHS(X/H) external temperature sensor is transmitted to the mixer module via the CAN bus.

or as a

- Mixer add-on with zone control

A separate outside temperature sensor must be connected to the mixer module. The assigned HC is controlled according to the outside temperature relevant for this zone.

If the terminal function is activated, the mixer module can be operated and the settings for the assigned heating circuit undertaken via the RoCon+ B1 control panel of the Daikin Altherma EHS(X/H).

In conjunction with the EHS157034 room control, the mixer module can also control the assigned heating circuit completely autonomously and independently of the heat generator.

Further explanations and possible settings for this menu can be found in Chap. 7.6.

Frost protection function

The integrated heating circulation pump is switched on at an outside temperature below the [Frost protection temperature] parameter value in order to prevent the heating system from freezing.

In addition, the feed, storage and connected room temperature sensors are also constantly monitored. If the temperature measured by one of these sensors falls below 7 °C (below 5 °C at room temperature), the antifreeze function is also activated.

If the heating feed temperature falls below 7 °C, the Daikin Altherma EHS(X/H) heats until the heating feed temperature reaches at least 12 °C.

The function is ended if the outside temperature rises above the set [Frost protection temperature] parameter value + 1 K and also there is no other activation condition.

INFORMATION

If low rate functions are activated,

[HT/NT function] parameter = Switch all off

or

[Smart grid] parameter = On

operation of the heat pump can be shut off completely for a limited period of time by the utility company. In these cases, regulation is not possible even in frost protection conditions and the device's internal heating circulation pump is not switched on.

These situations can be recognised if, in the [ Main menu Information Overview] menu in the operating data field: "Ext", the "High rate" value or "SG1" is displayed.

4.5.4 Heating

[→ Main menu → Configuration → Heating]

This menu is used to configure heating times and target feed temperatures for heating mode.

Heating curve

WARNING: FLAMMABLE MATERIAL

In the event of malfunction, the floor heating system, the screed or the floor structure could be damaged due to overheating.

• Prior to initial commissioning, set the maximum temperature limit in the RoCon+ HP control unit ([Max. feed temperature] parameter) to the maximum permitted system temperature prior to starting the emission measurement.
• Connect an overheating protection switch (in the building) at the "Ext" plug connection for external operating mode switch-over so that the Daikin Altherma EHS(X/H) is switched to the "Standby" or "Summer" operating mode. If the [Room thermostat] parameter = Yesor the [Interlink function] parameter = On, the overheating protection switch must be connected so that the room thermostat's switching contact is interrupted.
• If the floor heating is also used for room cooling, the connection notes in the above point also apply to the connection of a moisture protection switch in the building.

The heating curve is used to adapt the feed temperature to the characteristics of the building independent of the respective outside temperature (weather-compensated feed temperature control, see

Chap. 4.5). Generally speaking, the steepness of the heating curve describes the ratio of the feed temperature change to the external temperature change.

The heating curve is valid within the limits of the minimum and maximum temperatures set for the respective HC. The room temperature measured in the occupied area may differ from the required room temperature; these deviations can be kept to a minimum by installing a room thermostat or a room control.

The control unit is set at the factory in such a way that the heating curve does not independently adjust itself during operation.

The automatic heating curve adjustment can be activated ([Heating curve adaptation] parameter) if the outside temperature sensor and the room controller (EHS157034) are connected (see Chap. 4.5).

Start conditions for automatic heat slope adjustment:

• Outside temperature < 8^ C
• Operating mode is [Automatic 1 or Automatic 2]
• Duration of the setback period is at least 6 h

If no automatic heating curve adjustment is activated, the heating curve can be manually adjusted by adjusting the [Heat-Slope] parameter).

INFORMATION: MANUALLY ADJUSTING THE HEATING CURVE

Do not make any corrections to the set values for 1 - 2 days, and then only make them in small increments.

• Deactivate the external heat sources (e.g. stoves, direct sunlight, open windows).
• Fully open any radiator thermostat valves or actuators.
• Activate "Heating" operating mode. Approximate setting values:

Radiators and System 70: 1.4 to 1.6.

Floor heating: 0.5 to 0.9.

Tab. 4-5

Comfort heating

If the heat pump cannot cover the heating demand when outside temperatures are very low, heat is extracted from the storage tank and used for room heating. In rare cases (in systems with high required feed temperatures and low required hot water temperatures), the required feed temperature can be higher than the storage tank target temperature. In order to avoid short-term loss of comfort in heating mode for these systems, the [Comfort heating] parameter can be set to "On". At corresponding outside temperatures, the storage tank temperature is raised above the storage tank temperature set for the hot water requirement.

INFORMATION

If [Comfort heating] is set to "On", the power consumption of the heat pump may increase. In the default setting, [Comfort heating] is set to "Off".

Detailed explanations and possible setting values of this function can be found in Chap. 7.6.

4.5.5 Cooling

[→ Main menu → Configuration → Cooling]

This menu is used to make settings for cooling mode.

CAUTION: DANGER OF CONDENSATION

In the event of malfunction or incorrect parameter settings, the floor heating, the screed or the floor structure could be damaged due to condensation.

- Before initial commissioning and activation of cooling operation, set the minimum temperature limit in the RoCon controller ([Feed temperature lower limit] parameter) to the minimum permissible system temperature.

Prerequisites for cooling mode:

• Outside temperature > set value of room target temperature
• Outside temperature > set value of the [Start T-Out Cooling] parameter

4 Function

• [Cooling] operating mode activated.

- via menu "Operating mode" or

- via room thermostat function (cooling switching contact closed)

- No heat request active in the RoCon system of the heating system

INFORMATION

If the mean outside temperature falls below 4 °C when "Cooling" operating mode is active, the operating mode automatically switches to "Heating".

Renewed automatic operating mode switching to "Cooling" only takes place:

- if a room thermostat is connected to plug connection J16 (cooling) and

- the room thermostat's switching contact is closed and

- the mean outside temperature increases to over 10 °C again.

Cooling curve

[→ Main menu → Configuration → Cooling→Cooling curve]

The cooling curve determines the feed target temperature in cooling mode depending on the respective outside temperature. (for weather-compensated feed temperature control, see Chap. 4.5.3). Warmer outside temperatures result in a colder feed target temperature and vice versa. The cooling curve can be adapted to the condition of the building by four parameters (see Fig. 4-3).

1 [Start T-Out Cooling]
2 [Max T-Out Cooling]
3 [T-Flow Cooling start]
4 [T-Flow Cooling max]

Cooling parameters

[→ Main menu → Configuration → Cooling → Parameters]

This menu combines further parameters to determine feed target temperatures in cooling mode.

During weather-compensated T-HS control, the user can increase or decrease the feed target temperature by a maximum of 5 K with the [Cooling setpoint adjustment] parameter. A temperature reduction is limited by the [Feed temperature lower limit] parameter.

4.5.6 Domestic hot water

[→ Main menu → Configuration → DHW]

The domestic hot water preparation can be individually adapted to the behaviour and requirements of the users in this menu. This minimises energy consumption and increases comfort.

Settings for optional circulation pump

Depending on the [Circulation pump control] parameter, an optional circulation pump can be controlled synchronously with the selected time program for domestic hot water generation or with the time program for the circulation pump (see Chap. 4.3). During the release times of the selected time program, the circulation pump can be operated either continuously or cycled. This is defined with the [Circulation pump control] parameter.

Anti-legionella protection

This function is used to prevent bacterial contamination in the hot water tank by thermal disinfection. To do so, the hot water tank is heated 1× daily or 1× weekly to the disinfection temperature [Thermal disinfection temp.] depending on the [Thermal disinfection day] parameter. Disinfection starts at the specified start time [Thermal disinfection start time] and is active for one hour. An optionally connected circulation pump is automatically switched on during this time.

Detailed explanations and possible setting values of this function can be found in Chap. 7.6.5.

4.5.7 Additional program

[→ Main menu → Configuration → Addition]

This menu combines programs which simplify initial commissioning of the system.

Air purge function

[→ Main menu → Configuration → Addition → Ventilation]

By activating the ventilation function, the controller starts a fixed defined sequence program with start/slop operation of the integrated heating circulation pump and various positions of the integrated 3-way switching valves. Existing air can escape during operation via the automatic ventilation valve.

INFORMATION

The activation of this function does not replace correct venting of the HC.

The HC must be completely full before activating this function.

Relay Test

[→ Main menu → Configuration → Addition → Relay test]

This program allows testing of internal switching relays. This may be necessary in the event of malfunctions, error messages or as part of annual maintenance. When the menu is opened, all relays are deactivated. Selecting one or more relays activates them. When the menu is exited, all relay tests are terminated.

The relay test menu is operated in the same way as list entries (see Chap. 3.3.3). However, several relays can be activated in parallel in the relay list for testing. To do this, select the corresponding relay with "OK". Activated relays are indicated by a tick.

Floor screed dryout

[→ Main menu → Configuration → Addition → Screed]

The screed drying is started in the menu according to the settings in [Screed Program]. The program is used exclusively for the prescribed drying of newly created screed for floor heating systems.

The first day of the screed program begins after activation of the program at the change of day at 00:00.

Screed drying is a special function and is not interrupted by any other operating mode. It can only be activated by the heating expert for the direct HC and/or optionally connected mixed HCs. It must be activated separately for each HC.

INFORMATION

Before starting the screed drying, the [Room thermostat] and [Interlink function] parameters must be deactivated. During a short-term power failure, a previously activated screed drying is continued at the point of the interruption.

After activation of the screed drying, all weather-compensated control functions of the respective HC are switched off. The respective HC works as a constant temperature control regardless of the operating mode and switching times.

Already activated screed drying can be deactivated at any time. After ending the screed drying, the parameter is automatically set to "Off" and the HC works according to the currently set operating mode again.

Floor screed program

[→ Main menu → Configuration → Addition → Program]

This menu allows the individual adjustment of the factory settings for the duration and feed target temperatures of the screed drying. Changes can only be made after entering the specialist code.

Changing the screed program

A separate feed target temperature can be set for each day for a maximum duration of 28 days. The end of the screed program is defined by the first day without a preset feed target temperature.

Day Factory setting Day Factory setting
1 - 3 25	°C 10 - 19 55 °C
4 - 7 55	°C 20 40 °C
8 25 °C	21 25 °C
9 40 °C	22 - 26 -

Tab. 4-7 Default settings of the screed program

Fig. 4-4 Changing the screed program

Example: Increase the feed temperature of the 3rd day to 40 °C and stop the program on the 8th day [→ Main menu → Configuration → Addition → Program]:

1 Turn the rotary button clockwise until the day selection is set to 3.
2 Briefly press the rotary button to confirm ("OK"). → The temperature field is displayed in blue
3 Turn the rotary button clockwise until the temperature selection is 40 °C.

6 Turn the rotary button anticlockwise until the temperature selection is set to "Off".
7 Briefly press the rotary button to confirm ("OK"). → Day 8 to day 28 are set to "Off", Confirm icon is shown in blue
8 Briefly press the rotary button to confirm ("OK"). → The programming is saved and the menu is exited.

Typical screed programs

Function heating

The function heating serves as proof of the production of defect free work for the heating engineer. A prefabricated heating protocol relating to floor heating systems can be found on the manufacturer's Internet portal.

In this sense, the function heating (identical with "Heating" in EN 1264, section 5.2) is not considered as a heating process to achieve workability of the screed. Generally, a special screed curing heating and/or mechanical drying is required for this.

The heating of cement screeds should be carried out after 21 days at the earliest and of anhydrite screeds after 7 days at the earliest in accordance with the specifications of the manufacturer. The first heating begins with a feed temperature of 25 °C that must be maintained for 3 days. Afterwards, the heating is carried out with the maximum set feed temperature for the HC (limited to max. 55 °C ), which must be maintained for a further 4 days.

Due to the insulating effect of the DUO heating pipe for System 70, the screed function must be carried out at higher temperatures. The temperature profile must be adapted in the [Screed Program] parameter for this use case. For System 70, the heating begins at a temperature of 38 °C that is maintained for 3 days. The set maximum HC temperature (limited to 70 °C) is then maintained for 4 days.

4 Function

After the described heating process, it is not yet assured that the screed has reached the required moisture content for workability of the screed.

The moisture content in the screed must be checked by measurement prior to laying the surface covering.

INFORMATION

Procedure in accordance with EN 1264 Part 4:

For anhydrite and cement screeds, the HCs must be leak tested by a water pressure test after completion. The leak-tightness must be ensured immediately before and during the laying of the screed. The height of the test pressure is at least 1.3x the maximum permitted operating pressure.

Suitable measures must be taken if there is a risk of freezing, e.g. use of antifreeze agents or heating the building. If antifreeze agents are no longer necessary for the intended operation of the system, the antifreeze agent must be removed by draining and rinsing the system with at least 3 changes of the water.

Screed curing heating

The drying process for the screed cannot be exactly predicted. If there is a high degree of humidity, sometimes it can stop completely. The drying process can be speeded up by activating the floor heating (screed curing heating) or measures such as mechanical drying.

Each screed curing heating must be ordered separately by the client as an extra service in accordance with German construction contract procedures (VOB). The workability of the screed is a prerequisite for the top floor installer to start work so that he can produce defect free work.

With standard settings, the combined function and screed curing heating program can be activated to achieve the required residual moisture in the screed for workability of the screed (see Fig. 4-6). However, the residual moisture of the screed must basically be checked metrologically before the flooring can be laid.

Fig. 4-6 Chronological sequence of the screed program during the combined function and screed curing heating (for legend, see Tab. 4-8)

Detailed explanations and possible setting values of this function can be found in Chap. 7.6.

[→ Main menu → Error]

The error handling of the Daikin Altherma EHS(X/H) takes place in this menu. see Chap. 8.

4.8 Terminal

[→ Main menu → Terminal]

This menu can be used to operate and parametrise other devices (mixer module or added heat generators control components) in the RoCon system if the respective control panel has the required authorisation rights.

Functional IDs

The RoCon system offers a very wide range of application and extension options. The individual RoCon system components communicate via the CAN data bus. For this purpose, the RoCon BM2C PCBs and the RoCon+ B1 control panels of the Daikin Altherma EHS(X/H) as well as the optional RoCon U1 room station system components and RoCon M1 mixer module are connected to each other via data bus lines. These system components must be allocated unique functional IDs, so that the data exchange and assignment within the system functions without any problems.

The easiest way to assign the functional identifiers is to use the Configuration Wizard. This is carried out automatically during the first commissioning or can be started manually in case of extensions in the heating system in [ Main menu Configuration Wizard]. In addition, most identifiers can also be adapted to the RoCon system by parameter settings in this menu.

Tab. 4-10 Functional IDs in the RoCon system

4.8.1 Selecting the terminal address

[→ Main menu → Terminal → Address]

Setting of the terminal ID of the control panel for system access. The set value must be unique throughout the entire system. Confirmation of this parameter with the rotary button effects a new initialisation of the control unit.

All settings (except "Off") authorise the user of the control panel to activate the terminal function and thus to operate all RoCon system components with a valid device ID.

4.8.2 Bus-Scan for terminal function

[→ Main menu → Terminal → Bus scan]

After activating the "Bus scan", a list of detected devices (with assigned terminal address) is displayed in the menu [→ Main menu → Terminal] for selection. After selecting and confirming an external device, the terminal function for this device is activated. The control panel is then in terminal operation.

The local control panel acts as a remote control for the external device and the corresponding start screen is shown on the display. In this case, all the control functions are performed and saved 1:1 in the same way as on the external device. The displayed values and symbols are always taken over by the selected device.

To operate the local device, switch to the start screen of the external device. Press and hold the rotary switch to return to the menu of the local device.

INFORMATION

To perform the bus scan, a valid terminal address must be assigned to the RoCon+ B1 control panel of the Daikin Altherma EHS(X/H) or the EHS157034 room station. This can only be done with a specialist code. Contact your heating expert in this regard.

If the terminal function is to be used in the heating system, the terminal ID = 0 must be allocated to a control panel.

Example: Activate terminal operation for the heat generator with bus identification 2 [→ Main menu → Terminal → Bus scan]:

The bus scan is carried out. An overview of all devices that are found is displayed.

1 Turn the rotary switch clockwise until the BM1/BE1 #2 controller is displayed in blue.

2 Briefly press the rotary button to confirm ("OK").

→ The local control panel acts as a remote control for the heat generator with bus ID 2.

To end terminal operation and switch back to the operation of the assigned device, switch to the start screen of the external device. Press and hold the rotary switch to return to the menu of the local device.

INFORMATION

If the local control panel is used as a remote control for a mixer module, both the standard screen and the menu structure have been changed (see Chap. 9).

7.1 Explanation of the parameter tables

The parameter tables listed in Chap. 7.2 to Chap. 7.10 contain compact information on all parameters that are available in the respective menus and submenus of the controller (1st menu level, 2nd menu level).

In addition to the parameter designations, the tables contain information on setting ranges, factory settings, setting options or adjustment steps and brief explanations of the function.

In addition, they provide an explanation of the access rights for operation of the control unit. The following abbreviations are used for corresponding labelling:

BE Access right for the operator

HF Access right with technician code

If different entries are made in the BE and HF columns, the technician must be logged in before selecting the parameter level in order to obtain the status entered in the HF column (see Chap. 4.5).

Status:

N Not visible

E Visible and configurable

S Visible

INFORMATION

Changing some parameters requires a restart of the device. This takes a few minutes. No further settings can be made during this time. The restart can be delayed by 5 minutes by selecting "Later" in response to the "Restart required. Perform now?" prompt.

8 Faults and malfunctions

DANGER: RISK OF ELECTROCUTION

Electrostatic charges can lead to voltage arcing that can destroy the electronic components.

- Ensure potential equalisation prior to touching the switching panel PCB (e.g. by touching the switching panel holder).

The electronics of the Daikin Altherma EHS(X/H) indicate an error by red illumination of the status display, the appearance of the error screen on the display (see Chap. 8.4) and the appearance of the error symbol on the start screen. An integrated error memory stores up to 15 error messages (see Chap. 8.3).

INFORMATION

A list of all error codes can be found in the Daikin Altherma EHS(X/H) installation and maintenance instructions, chapter "Errors, malfunctions, messages".

Troubleshooting: Error code E90XX

An error reset can be performed. This can be started from the currently displayed error screen. If the error screen has been exited, it can be recalled via [ Main menu Error Screen].

If the same error is displayed again shortly, the cause of the error must be found and rectified by a specialist. In the meantime, emergency operation may be maintained. Emergency operation can be permitted via [ Main menu Error Emergency operation], see Emergency operation. If emergency operation has not been permitted, it can be started from the current error screen.

Troubleshooting: Other error codes

The cause of the error must be found and rectified by a specialist. In the meantime, emergency operation may be maintained. Emergency operation can be permitted via [ Main menu Error Emergency operation], see Emergency operation. If emergency operation has not been permitted, it can be started from the current error screen.

INFORMATION

To ensure that the error has not been caused by incorrect settings, set all the parameters back to the factory settings before possible replacement of components (see Chap. 4.5.9).

If it is not possible to determine the cause of the fault, please consult a service technician.

Please have the essential device data ready for this:

8.1 Emergency operation

[→ Main menu → Error → Emergency operation]

If the heat pump fails, the backup heater or another external heat generator can be used as an emergency heater. If [Emergency operation] is set to "Yes", in the event of an error, emergency operation is automatically activated. Otherwise, emergency operation can only be started in the event of an error via the error screen.

If emergency operation is started via the error screen, the [Emergency operation] parameter remains set to "Yes", i.e. emergency operation is also started automatically in the event of future errors. If this is not desired, the [Emergency operation] parameter must be reset to "No" after the error has been corrected.

8.2 Manual Operation

[→ Main menu → Error → Manual operation]

In manual operation, the heat pump is controlled to a fixed feed temperature. Manual operation should only be used for diagnostic purposes. Manual operation is started by setting the [Manual operation status] parameter to "Active". The desired feed temperature is set by [Temperature, manual operation] parameter.

With hydraulically controlled priority operation for domestic hot water preparation, it must be ensured that the feed target temperature set in manual operation is sufficient to achieve the stored hot water target temperature ([Hot water temp. setpoint 1] parameter).

8.3 Error protocol

9 Mixer module

In addition to the direct HC, the emitter type can be extended by additional HCs using mixer modules EHS157068. These additional HCs can be configured independently of the direct HC. The configuration is similar to the configuration of the direct HC (see Chap. 4). Only a limited selection of parameters and functions is available (see Chap. 9.2).

The optional EHS157068 mixer module does not have its own control unit. For configuration and operation, it must be connected to the RoCon+ controller installed in the heat generator or to a EHS157034 room station via a CAN bus line. The mixer module can be operated in terminal mode from both operating units (see Chap. 4.8).

A unique device ID ( ≥ 1) must be set on the address switch of the mixer module (see Fig. 9-1) for the HC to be controlled by this mixer module, which must be synchronised with the [Heating circuit assignment] parameter of the mixer module (see Tab. 4-10).

Fig. 9-3 Mixer module start screen

The start screen for the mixer module (Fig. 9-3) is a reduced version of the RoCon+ HP start screen. The meaning of the icons is the same Tab. 3-4, but the mixer temperature is the only system temperature displayed (Fig. 9-3, item 1).

The start screen for the mixer module is displayed in the menu [ Main menu Terminal Mixer #X]. Briefly pressing the rotary switch switches to the mixer menu. A long press of the rotary switch switches to the menu of the local control panel.

10 Glossary

Mode Request by the user or the	control unit for the function of the heat generator (e.g. room heating, domestic hot water generation, standby, etc.)
Backup requirement	Operating situation in which the required feed temperature cannot be reached efficiently or at all using the heat pump process. A heater booster (e.g. a backup heater) is therefore integrated to support the Daikin Altherma EHS(X/H) in generating heat.
Backup heater	Optional electric heater booster for general support of the Daikin Altherma EHS(X/H) during heat generation.
Heating curve Mathematical rela	tionship between the external temperature and the feed temperature setpoint in order to achieve the required room temperature at all external temperatures.
Refrigerant	A substance used for heat transfer in the heat pump process. At low temperature and low pressure, heat is ab-sorbed and at high temperature and a high pressure, heat is emitted.
Anti-legionella system	Periodic heating of the storage water to >60 °C for the preventative elimination of pathogenic bacteria (so-called legionella) in the hot water circuit.
Off-peak mains connection (HT/NT)	A special mains connection to the energy supplier, which offers various cheaper rates during so-called low-load periods for electrical current (day-, night-, heat pump current, etc.).
Parameters A value that influenc	es the execution of programs or processes or defines specific states.
Control unit	Device electronics that are used to control the processes for the heat generation and heat distribution of the heating system. The control unit consists of a number of electronic components. The most important component for the operator is the control panel in the front area of the heat generator, which includes program selec-tion keys, rotary buttons and display.
Return flow	Part of the hydraulic circuit that directs the cooled water from the radiators in the rooms back to the heat gen- erator via the piping system.
Switching time program	Program for setting the times on the control unit in order to determine the regular heating, reducing and hot water cycles.
Smart Grid (SG)	Intelligent use of energy for inexpensive heating. By using a special electricity meter, it is possible to receive a "Smart Grid signal" from the utility company.Depending on the signal, the heat pump is shut off or operated as normal or at higher temperatures.
Flow Part of the hydraulic circuit	that diverts the heated water from the heat generator to the heating surfaces.
Domestic hot water circuit This is	the water circuit in which cold water is heated and diverted to the hot water tap.
Domestic hot water generation	Operating status of the heat generator in which heat with elevated temperatures is generated and fed to the hot water circuit, e.g. loading of the hot water storage tank.
Heat pump process	In a closed-loop refrigerant circuit, the refrigerant absorbs the heat from the ambient air. By means of com-pression, the refrigerant achieves a higher temperature that is transferred to the heating system (thermody-namic cycle).
Heat exchanger	A component that transfers thermal energy from one circuit to another. The two circuits are hydraulically se-parated from one another by a wall in the heat exchanger.
Weather-dependent feed tem-perature control	A suitable feed temperature is determined from the measured value for the external temperature and a defined heating curve; this temperature is used as the target value for temperature control in the heating unit.
Circulation pump	The circulation pump is an additional electrical circulation pump that permanently circulates the hot water in the hot water lines, thus providing it immediately at every tap. This circulation is especially useful in extensive pipeline networks. In systems without a circulation line, first the water cooled in the sampling line escapes dur-ing the sampling process until the sampling line has been sufficiently heated by the inflowing hot water.
Heater booster	Additional heat generator (e.g. backup heater or external boiler) integrated in the heating system to achieve the required feed temperature setpoint in the case of an inadequate or inefficient heat pump process.
