Tab. 2-1 Permissible combinations of Daikin Altherma EHS(X/H) internal units and Daikin heat pump external units

Any other use outside the intended use is considered as improper. The operator alone shall bear responsibility for any resulting damage.

Intended use also includes compliance with the maintenance and service conditions.

Replacement parts must at least satisfy the technical requirements defined by the manufacturer.

This is the case, for example, with original spare parts.

2.4 Instructions for operating safety

2.4.1 Before working on the hydraulic system

- Work on the Altherma EHS(X/H) (such as setup, servicing, connection and initial start-up) is only to be carried out by persons who are authorised and who have successfully completed qualifying technical or vocational training and who have taken part in advanced training sessions recognised by the appropriate responsible authorities for the specific activity. This, in particular, includes heating specialists and climate control technicians who have experience, as a result of their technical training and their knowledge of the subject, of proper and appropriate installation and maintenance of heating, climate control and cooling installations and heat pumps.

• Switch off the external main switch before starting any work on the Daikin Altherma EHS(X/H) and secure it against unintentional switch-on.
• Lead tamper-proof seals must not be damaged or removed.

2 Safety

• Make sure that the safety valves comply with the requirements of EN 12828 when connecting on the heating side, and with the requirements of EN 12897 when connecting on the domestic water side.
• Only original Daikin replacement parts may be used.
• When working on the hydraulics, you must first drain the water or release the pressure using the internal KFE valve. Otherwise hot water can jet out under pressure and result in injury.

2.4.2 Electrical installation

• Electrical installation may be carried out only by electrical engineers and in compliance with the valid electro-technical guidelines as well as the regulations of the relevant energy supply company (EVU).
• Compare the mains voltage (\~230 V, 50 Hz or \~400 V, 50 Hz) indicated on the type plate with the supply voltage before connecting to the mains.
• Before beginning work on live parts, disconnect all of the systems circuits from the power supply (switch off main switch, disconnect fuse) and secure against unintentional restart.
• Equipment covers and service panels must be replaced as soon as the work is completed.

2.4.3 Working on cooling systems (heat pump)

The Daikin Altherma EHS(X/H) requires fluorinated greenhouse gas for its function.

i

For work on stationary refrigeration systems (heat pumps) and air conditioning systems, proof of expertise is required in the European Community according to the F-Gases Directive (EC) No. 303/2008.

– up to 3 kg coolant fill quantity: Expert certificate category II
- 3 kg coolant fill quantity or over: Expert certificate category I

• Always wear safety goggles and protective gloves.
• When working on the refrigerant circuit, ensure that the workplace is well ventilated.
• Never carry out work on the refrigerant circuit in closed rooms or work pits.
• Do not let coolant come into contact with open fire, embers or hot objects.
• Never allow coolant to escape into the atmosphere (high pressure at the point of the leak).
• When removing the service pipes from the filling connections, never hold the connections in the direction of your body. Residual refrigerant could escape.
• Components and spare parts must at least satisfy the technical requirements defined by the manufacturer.

2.4.4 Site of installation

For safe and fault-free operation, it is necessary that the installation location of the Daikin Altherma EHS(X/H) fulfils certain criteria.

Related information can be found in chapter 4.2.

Information on the installation site of other components can be found in the associated documentation supplied with them.

2.4.5 Requirements for the heating and storage water

Damage due to deposits and corrosion: observe the current technological regulations to prevent corrosion products and deposits.

Minimum requirements regarding the quality of filling and top-up water:

• Water hardness (calcium and magnesium, calculated as calcium carbonate): ≤3 mmol/l
  • Conductivity: ≤1500 (ideal 100) S/cm
• Chloride: ≤250 mg/l
• Sulphate: ≤ 250 mg/l
• pH value: 6,5 - 8,5

Measures for desalination, softening or hardness stabilisation are necessary if the filling and top-up water have a high total hardness (>3 mmol/l – total of the calcium and magnesium concentrations, calculated as calcium carbonate). We recommend the use of Fernox KSK limescale and corrosion protector. For other properties deviating from the minimum requirements, suitable conditioning measures are necessary to maintain the required water quality.

Using filling water and top-up water which does not meet the stated quality requirements can cause a considerably reduced service life of the equipment. The responsibility for this lies solely with the operator.

i

If an optional external heat generator is connected, these minimum requirements also apply to the filling and supplementary water for this heating circuit.

2.4.6 Heating system and sanitary connection

• Create a heating system according to the safety requirements of EN 12828.
• The plumbing connection must comply with the requirements of EN 12897. The requirements of the following must also be observed:
• EN 1717 – Protection against pollution of potable water installations and general requirements of devices to prevent pollution by backflow
• EN 61770 – Electric appliances connected to the water mains – Avoidance of back-siphonage and failure of hose-sets
• EN 806 – Specifications for installations inside buildings conveying water for human consumption
  – and, in addition, the country-specific legislation.

During operation of the indoor unit with an auxiliary heat source, the storage tank temperature may exceed 65 °C, above all when solar energy is used.

- For this reason, some form of scalding protection needs to be included when you install the system (hot water mixing device, e.g. VTA32).

i

The domestic water quality must comply with the EU Guideline 98/83 EC and the regionally-applicable regulations.

If the indoor unit is connected to a heating system with steel pipes, radiators or non-diffusion-proof floor heating pipes, sludge and chips can enter the hot water storage tank and cause blockages, local overheating or corrosion damage.

• To prevent possible damage, install a dirt filter or sludge separator into the heating return flow of the system (SAS 1 or SAS 2).
• The dirt filter must be cleaned at regular intervals.

2.4.7 Operation

The Daikin Altherma EHS(X/H):

• Do not operate until all installation and connection work is completed.
• Only operate with a completely full storage tank (Level indicator) and heating circuit.
• Operate at a maximum pressure of 3 bar.
• Only connect with a pressure reducer on the external water supply (supply line).
• Only operate the with the specified quantity of coolant and the type of coolant specified.
• Only operate if the protective cover is installed.

The prescribed maintenance intervals must be maintained and the inspection work must be carried out.

2.4.8 Instruct the operator

• Before you hand over the Daikin Altherma EHS(X/H), explain to the user/owner how to operate and check the system.
• Hand over the technical documentation (this document and all supporting documents) to the user and advise him that these documents must be made available at all times and be stored in the immediate vicinity of the unit.

4.2 Set-up

CAUTION!

• Only erect the Daikin Altherma EHS(X/H) when a sufficient ground load-bearing capacity, of 1050 kg/m² plus safety margin, has been assured. The ground must be flat and level.
  • Outdoor installation is not permitted.
• Erection in explosion-risk environments is not permitted.
• The electronic control system must not be subjected to atmospheric factors under any circumstances.
• The storage tank must not be exposed to continuous direct sunlight, as the UV radiation and the effects of the weather will damage the plastic.
• The Daikin Altherma EHS(X/H) must be installed in a manner protected from frost.
• Make sure that the supply company does not provide corrosive domestic water.

- Suitable water treatment may be required.

WARNING!

The plastic wall of the storage tank on the Daikin Altherma EHS(X/H) may melt due to the effects of external heat (>80 °C) and in the extreme case, can catch fire.

- Erect the Daikin Altherma EHS(X/H) only at a minimum distance of 1 m to other heat sources (>80 °C) (e.g. electric heater, gas heater, chimney) and flammable materials.

CAUTION!

If the Daikin Altherma EHS(X/H) is not erected adequately lower the flat solar panels (the top edge of the of the storage tank is higher than the bottom edge of the solar panels), the unpressurised solar system in the outdoor area will be unable to drain completely.

- Erect the Daikin Altherma EHS(X/H) with a DrainBack solar connection at a sufficient depth to the flat solar panels (observe the minimum gradient in the solar connecting lines).

• Remove packing and dispose of it in an environment-friendly manner.
• Remove the cover plates on the storage tank (fig. 4-4, item B) and unscrew the threaded pieces (fig. 4-4, item F) from the apertures on which the handles are to be mounted (fig. 3-2 to fig. 3-5, item 24).

4.4 Water connection

CAUTION!

If the Daikin Altherma EHS(X/H) is connected to a heating system with steel pipes, radiators or non-diffusion-proof floor heating pipes, slurry and swarf could enter the hot water storage tank and cause blockages, local over-heating or corrosion.

• Flush the feed pipes before filling the heat exchanger.
• Rinse out the heat distribution network (in the existing heating system).
• Install the dirt filter or sludge separator into the heating return flow (see chapter 2.4.6).

CAUTION!

If the Daikin Altherma EHS(X/H) is connected to a cold water line, where steel pipes are used, chips can enter the special steel corrugated pipe heat exchanger and remain there. This can lead to contact corrosion damage and subsequently to leakage.

• Flush the feed pipes before filling the heat exchanger.
  • Install contamination filter in the cold water feed (see chapter 2.4.6).

Only Daikin Altherma EHS(X/H)B...

CAUTION!

If the heat exchanger for charging the pressurised solar system (fig. 4-1 / fig. 4-2, item 8+9) has an external heating unit (e.g. wood-burning boiler) connected to it, an excessive flow temperature at these connections can damage or destroy the Daikin Altherma EHS(X/H) B.

- The feed flow temperature of the external heater should be limited to max. 95 °C.

In accordance with EN 12828 you must install a safety valve at or in the immediate vicinity of the heat exchanger, with which you can limit the maximum permissible operating pressure in the heating system. There should be no hydraulic blocking elements between the heat generator and the safety valve.

Any steam or heating water which may escape must be diverted by a suitable blow-off line with constant gradient in a frost-protected, safe and observable manner.

A diaphragm expansion vessel of adequate dimensions and pre-set for the heating system must be connected to the Daikin Altherma EHS(X/H). There should be no hydraulic blocking elements between the heat generator and the diaphragm expansion vessel.

Daikin recommends integrating a mechanical manometer for the filling of the heating system.

• For drinking water lines, comply with the EN 806 and DIN 1988 stipulations.
• Install the Daikin Altherma EHS(X/H) near to the removal point to dispense with the need for a circulation line. If a circulation line is absolutely essential, it must be installed in accordance with the schematics in section 9 "Hydraulic system connection".

4.4.1 Aligning the connections of the heating feed and return flow

The connections for the heating feed and return flow can be directed out of the unit upwards or downwards in order to adapt to the on-site conditions in the most optimum manner.

The unit is delivered with the connections exiting upwards as standard. In order to direct the connections out from the back of the unit you must carry out the following conversion steps:

- Remove the cover hood and the upper thermal insulation (see chapter 4.3).

A B C H G F B C D E

Fig. 4-10 Heating feed and return flow connections aligned upwards

• Pull off both the plug brackets on the connection couplings (fig. 4-10, item C).
  • Pull off both connection couplings (fig. 4-10, item B).

CAUTION!

When working on the hydraulics you must take care of the mounting position of the O-rings to prevent damage to the O-rings and consequent leaks.

• Always place O-rings on the part to be inserted after a plug connection has been removed or before it is installed.

• Connection of heating lines by plug connection must be without tension. Establish suitable tension relief particularly for connection with flexible lines (not breathable!).

• Remove retainer plate (fig. 4-10, item A).
  • Pull off the plug bracket on the closing plug (fig. 4-10, item D).
  • Pull out the closing plug (fig. 4-10, item E).

• Rotate the angular piece (fig. 4-10, item H) by 90^ to the back.
  • Pull off the plug bracket on the elbow (fig. 4-10, item G).
• Pull the elbow (fig. 4-10, item F) carefully to the rear out of its horizontal mount so that the retainer plate (fig. 4-11, item A) can be inserted in the gap vertically.

A B G F C H E D C B

Fig. 4-11 Heating feed and return flow connections aligned to the rear

- Slide the retainer plate between the elbow and its horizontal mount and insert the elbow (fig. 4-11, item F) back in its mount through the central hole in the retainer plate.

CAUTION!

If the plug brackets are not inserted properly, the couplings can come loose in their mounts which may result in high levels of fluid escape and continuous fluid escape.

• Before plugging in a plug bracket, make sure that the plug bracket engages in the groove in the coupling. To do this, insert the coupling into the mount until the groove becomes visible through the plug bracket mount.

• Insert the plug bracket up to the stop.

• Secure the elbow back into its mount with plug bracket (fig. 4-11, item G).

• Insert both connection couplings (fig. 4-11, item B) through the retainer plate in the side mounts.
• Secure both connection couplings in their mounts with the plug brackets (fig. 4-11, item C).
• Insert the closing plug (fig. 4-11, item E) in the top mount.
• Secure the closing plug with the plug bracket (fig. 4-11, item D).
• Cut out the side transit points in the thermal insulation (fig. 4-12, item A) using a suitable tool.

4.4.2 Connecting hydraulic lines

Requirement: Optional accessories (e.g. Solar, Backup-Heater) mounted on the Daikin Altherma EHS(X/H) according to the specifications of the instructions included.

- Check cold water pressure (maximum 6 bar).

- At higher pressure in the drinking water line, a pressure reducer must be installed.

• Establish hydraulic connections at the Daikin Altherma EHS(X/H).
• Position and dimensions of the heating connections to be taken from fig. 4-1 / fig. 4-2 and from tab. 3-1.
• Pay attention to the stipulated tightening torque (see section 10.3 "Tightening torque").
• Design the lines as such that the sound attenuation cowl can be applied without any problem following assembly.
• Connect the water for filling or refilling the heating system as specified by EN 1717 to avoid contamination of drinking water by backwash.

- Connect a drain line to the safety overpressure valve and connect a diaphragm drain container in accordance with EN 12828.

• Check the seating of the drain hose on the overpressure valve.
• If required, attach your own hose and route accordingly.

- Carefully insulate pipe lines against heat loss and so as to avoid the formation of condensation (insulation thickness at least 20 mm).

• Water shortage protection: The pressure and temperature monitoring of the control unit safely switches off the Daikin Altherma EHS(X/H) in the event of a water shortage. No additional water shortage protection is needed in the construction.
• Avoid damages caused by deposits and corrosion: Observe the relevant regulations of technology to prevent creation of corrosion products and deposits.

Minimum requirements regarding the quality of filling and supplementary water:

– Water hardness (calcium and magnesium, calculated as calcium carbonate): ≤3 mmol/l
- Conductivity: 1500 (ideal 100) S/cm
- Chloride: 250 mg/l
– Sulphate: 250 mg/l
- pH value (heating water): 6,5 - 8,5

In the case of filling and top-up water with a high overall hardness or other properties that deviatte from the minimum requirements, measures for the desalination, softening, hardness stabilisation or other suitable conditioning measures are required to maintain the required water quality.

WARNING!

There is a danger of scalding at hot water temperatures over 60 °C. This is possible, when solar energy is used, with a connected external heating device, when the Legionella protection is activated or when the domestic hot water target temperature is set higher than 60 °C.

• Install scald protection (hot water mixer (e.g. VTA32).

- Connect the drain hose to the connection piece for the safety overflow (fig. 3-2 to fig. 3-5, item 23).

• Use transparent drain hose (draining water must be visible).
• Connect the drain hose to an adequately dimensioned waste water installation.
• Drain should not be lockable.

4.5 Electrical connection

WARNING!

Touching live parts can result in an electric shock and lead to potentially fatal injuries and burns.

• Before beginning work on live parts, disconnect all of the systems circuits from the power supply (switch off main switch, disconnect fuse) and secure against unintentional restart.
• The electrical connection and working on the electrical components should only be performed by electrical engineers in compliance with valid standards and guidelines as well as the specifications of the energy supply company.
• The equipment covers and maintenance opening covers must be re-fitted immediately after completion of the work.

CAUTION!

In the controller housing of the Daikin Altherma EHS(X/H), in continuous running, elevated temperatures can be generated. This can result in currently-carrying wires from reaching higher temperatures during operation due to self-heating. For this reason, these lines need to have a continuous use temperature of 90 °C.

- For the following connections, use only cables with a long-term use temperature ≥slant 90^ : - Exterior heat pump unit - Optional: Electrical Backup-Heater (EKBUxx)

Mains supply 230 V, 50 Hz (Connection plan in this instruction manual)

4.5.6 Mains connection Daikin Altherma EHS(X/H)

A flexible cable for the mains connection is already connected internal to the device.

• Check the supply voltage (\~230 V, 50 Hz).
• Disconnect the junction box of the domestic installation.
• Connect the cable for the mains connection on the Daikin Altherma EHS(X/H) to the junction box of the domestic installation via an all-pole disconnecting main switch to be installed by the customer (separate isolator according to EN 60335-1). Ensure that the polarity is correct.

The external device and optional accessories must be connected separately to the regulator on the Daikin Altherma EHS(X/H). To do so, the cover panel of the Daikin Altherma EHS(X/H) must be removed (see section 4.3) and if necessary, the control housing opened (see section 4.5.7).

Fig. 4-29 Connection of exterior heat pump unit

When switching off the heat pump exterior unit using a switching system prescribed by the energy supply company (EVU), the internal Daikin Altherma EHS(X/H) device is not disconnected (see section 4.5.18).

4.5.9 Connection of external temperature sensor RoCon OT1

The exterior heat pump unit of the Daikin Altherma EHS(X/H) has a built-in exterior temperature sensor which is used to regulate the inflow temperature depending on the weather, with frost protection function.

The weather-controlled flow temperature regulation can be optimised with the RoCon OT1 optional external temperature probe, which can be installed on the north face of the building.

If the Daikin Altherma EHS(X/H) is used in a CAN bus system as a master ("terminal function" for the remote control of other data bus devices), the exterior temperature sensor RoCon OT1 must be connected directly to the regulator RoCon HP on the master and not to the remote controlled device (mixer circuit module EHS157068 or a different heat generator).

Choose a location at about one third of the building height (minimum distance from floor: 2 m) at the coldest side of the building (North or North-East). Thereby, exclude the proximity of external heat sources (chimney, air shafts) and direct sunshine.

- Place external temperature sensors in such a way that the cable exit points face downwards (prevents humidity ingress).

CAUTION!

The parallel routing of sensor and mains lines within an installation pipe can cause considerable malfunctioning in the regular operation of the Daikin Altherma EHS(X/H).

• Always lay the sensor line separately.

4 Set-up and installation

• Connect the exterior temperature sensor to a twin-core sensor line (minimum diameter 1 mm ^4 ).
  • Install the sensor line to the Daikin Altherma EHS(X/H).
• Connect the sensor line to the plug connection J8 on the board RoCon BM1 (see fig. 4-30).

Fig. 4-30 Connection of the exterior temperature sensor RoCon OT1 to the Daikin Altherma EHS(X/H) (operating as a single solution or master in a data bus)

After connecting the exterior temperature sensor RoCon OT1 to the regulator RoCon HP of the Daikin Altherma EHS(X/H), the parameter [Outside Config] must be set to "On".

4.5.10 Connection of an external switching contact

By connecting an external switching contact (fig. 4-31) the operating mode of the Daikin Altherma EHS(X/H) can be changed.

The current operating mode can be switched thanks to a changing resistance reading (tab. 4-1). Changing the operating mode is only effective as long as the external switching contact is closed.

The operating mode has an effect on the direct circuit of the Daikin Altherma EHS(X/H), and on all other heating circuits that can be optionally connected to this device.

The operating mode shown in the controller display can deviate from the operating mode activated in the rotary switch setting ⏻...

An operating mode activated by an external switch contact is shown on the controller by "EXT.", followed by the symbol of the operating mode (see operating instructions for the controller).

If special functions, such as "Manual Operation" are activated, the input is not evaluated.

Tab. 4-1 Resistance values for the evaluation of the EXT signal

When the resistance readings are greater than the value for "Automatic 2", the input will be ignored.

NOTE REGARDING THE CONNECTION OF A DAIKIN SOLAR SYSTEM

By means of the function [HZU] integrated into the RoCon HP integrated HZU control unit (see operating manual for the control unit) it is not necessary to connect the EXT connection with the connection of the burner blocking contact of the Daikin solar system.

4.5.11 External demand signal (EDS)

By connecting the EDS switch contact to the Daikin Altherma EHS(X/H) (fig. 4-32) and through the corresponding parameterisation in its RoCon HP control unit, a heating demand can be generated via an external switch contact. If the switch contact is closed, the Daikin Altherma EHS(X/H) switches to the heating mode. The flow temperature is adjusted to the temperature that is set in the parameters [T-Flow Day].

The EDS switching contact has preference of a request via the room thermostat.

In Cooling, Stand-by, Manual and Summer mode, the switching contact is not evaluated. In addition, the heating limits are not taken into consideration.

Warning!

When contacting a damaged connection cable of the Backup-Heater this can cause electrocution and thus cause life-threatening injury and burns.

- Do not repair the connection cable of the Backup-Heater.

→ Always replace the complete Backup-Heater.

For heating support or as an alternative to an electrical Backup-Heater (see section 4.5.12) you can connect an external heat generator (e.g. gas or oil boiler) to the Daikin Altherma EHS(X/H).

The heat supplied by the external heat generator must be added to the unpressurised storage tank water in the Daikin Altherma EHS(X/H) hot water storage tank.

• Carry out hydraulic connection in accordance with one of the two following possibilities:
  a) unpressurised via connections (solar infeed and solar return) of the hot water tank or
  b) oh+whit types Daikin Altherma EHS(X/H) B, via the integrated pressurised solar heat exchanger.

- Observe the instructions concerning hydraulic connections (see chapter 2.4)

– Examples of hydraulic connection (see chapter 9).

Demand from an external heat generator is switched to the RTX-EHS circuit board via a relay (see fig. 4-36). The electrical connection to the Daikin Altherma EHS(X/H) is possible as follows;

a) External heat generator has a potential-free switch contact connection for heat demand:

- Connection to K3, if the external heat generator takes over the hot water generation and heating support (setting parameter [Function Heating] = 2) or

- Connection to K1 and K3 if two external heat generators are being used (setting parameter [Function Heating] = 3). Here K1 switches the external heat generator (e.g. gas or oil boiler) for heating support and K3 the external heat generator (EKBUxx) for hot water generation.

- Connection on AUX connection A (see section 4.5.17)

b) External heat generator can only be switched via the mains power supply: Connection (\~230 V, maximum load 3000 W) at K1 and K3.

Caution!

Risk of voltage arcing.

- The connections on the RTX-EHS circuit board must not be used for switching the mains voltage (\~230 V) and protective low voltage (SELV = "Safety Extra Low Voltage") at the same time.

• Suitable electrical connection from the relevant installation instructions for the external heat generation.
• Connect external heat generation to the Daikin Altherma EHS(X/H) (fig. 4-36).
  Connection X1 is a screw terminal.
  Isolated 6.3 x 0.8 mm push-on receptacles are required for connections X2_1/2/3.

Fig. 4-41 Connection switching contact (AUX output)

The relays to be used for Variant 2 (switched power > 15 W) must be suitable for 100 % switch-on duration.

The switch-over contact A-A1-A2 can be used, for example, to control the heat generator in bivalent heating systems of Daikin Altherma EHS(X/H) and oil or gas boiler. Examples of the hydraulic system incorporation are shown in chapter 9.

4.5.18 Low tariff mains connection (HT/NT)

If the outdoor unit is connected to a reduced tariff mains connection, the voltage-free switching contact S2S of the receiver which evaluates the low tariff input signal emitted by the electricity supply company (EVU) must be connected to the plug J8, connection EVU on the RoCon BM1 circuit board (see fig. 4-42).

When the parameter [HT/NT Function] > 0 is set, certain system components are switched off during peak tariff times (see operating manual of the control unit).

The following types of reduced tariff mains connection are standard:

• Type 1: With this type of low-tariff mains connection, the power supply to the heat pump exterior unit is not disconnected.
• Type 2: With this type of low-tariff mains connection, the power supply to the heat pump exterior unit is disconnected after a certain period of time.
• Type 3: With this type of low-tariff mains connection, the power supply to the heat pump exterior unit is disconnected immediately.

The potential-free switching contact S2S can be designed as a normally-closed or a normally-open switching contact.

a) If it is designed as an open switching contact, then the parameter [HT/NT Contact] = 1 must be set.
If the EVU transmits the reduced tariff signal, switching contact S2S is opened. The system switches to "Mandatory OFF". If the signal is sent again, the potential-free switching contact S2S closes and the system resumes operation.
b) If it is designed as an closed switching contact, then the parameter [HT/NT Contact] = 0 must be set.
If the EVU transmits the reduced tariff signal, switching contact S2S is closed. The system switches to "Mandatory OFF". If the signal is sent again, the potential-free switching contact S2S opens and the system resumes operation.

4.5.19 Connection intelligent controller (Smart Grid - SG)

Once the function is activated by parameter [SMART GRID] = 1 (see operating manual for the control unit), depending on the signal from the energy supply company, the heat pump is switched to Stand-by, Normal or an operating mode with higher temperatures.

To do so, the potential-free contacts SG1/SG2 of the intelligent controller must be connected to the J8 plug, connections Smart Grid and EVU, on the RoCon BM1 circuit board (see fig. 4-43).

As soon as the Smart Grid function is active, the HT/NT function is deactivated automatically. Depending on the value of the parameter [Mode SG] the heat pump operated in a different manner (see operating manual for the control unit).

4.6 Laying coolant lines

- Check whether oil trap arc necessary.

- Required if Daikin Altherma EHS(X/H) is not installed at ground level with the heat pump exterior unit (fig. 4-44, H_0 ≥ 10 m).

- At least one oil trap arc must be installed every 10 m difference in height (fig. 4-44, H = clearance from oil trap arc to oil trap arc).

– Oil trap arc only required in gas line.

• Install lines with bending unit and an adequate clearance to electrical lines.
  • Only solder with light nitrogen flow (hard soldering only).
• Do not apply heat insulation to joins until after start-up (for purposes of leakage search).
• Establish flange connections and connect to the units. (Ray attention to the tightening torque, see section 10.3 "Tightening torque").

4.7 Pressure test and filling the coolant circuit

RISK OF ENVIRONMENTAL DAMAGE!

Important information regarding the coolant used.

The entire heat pump system contains refrigerant with fluoridated greenhouse gases which damage the environment if released.

Coolant type: R410A

GWP* value: 2087,5

* GWP = Global Warming Potential

• Fill in the total coolant filling quantity on the supplied label on the heat pump exterior unit (for information consult the installation instructions for the heat pump exterior unit).
• Never allow coolant to be released into the atmosphere - always suction it off and recycle using a suitable recycling device.

• Perform pressure test with nitrogen.

- Use nitrogen 4.0 or higher.

- Maximum 40 bar.

• After leak search is complete, completely drain.

- Vacuum lines.

- Pressure to be achieved: 1 mbar absolute.

– Time: minimum 1 h

• Check whether additional coolant is needed for primer filling, fill where necessary.
• Open stop valve on exterior unit completely until the stop. Tighten loosely.
• Reassemble valve caps.
• Check whether the storage tank temperature sensors t_DHW1 and t_DHW2 are inserted to a depth of 80 cm.

4.8 Filling the system with water

Only fill the Daikin Altherma EHS(X/H) following the sequence stated below and once all installation work is complete.

4.8.1 Checking the water quality and adjusting the pressure gauge

- Observe the information on the water connection and water quality in accordance with section 4.4.

The correct minimum pressure marking must be set on the pressure gauge installed by the customer before filling the system for the first time:

- Rotate the pressure gauge glass in such a way that the minimum pressure mark corresponds to the system height +2 m (1 m water column = 0.1 bar).

4.8.2 Filling the hot water heat exchanger

• Open the shutoff valve for the cold water supply pipe.
• Open the hot water tap connections so that the draw-off volume can be set as high as possible.
• Once water has been discharged from the tap connections, do not interrupt the cold water flow; this will ensure that the heat exchanger will be fully vented and that any impurities or residue will be discharged.

4.8.3 Filling the storage tank

See chapter 7.3.

4.8.4 Filling the heating system

See chapter 7.4.

5 Start-up

WARNING!

A Daikin Altherma EHS(X/H) that is installed or started incorrectly may not operate properly and is dangerous for the health and safety of individuals.

- The Daikin Altherma EHS(X/H) may only be started up by authorised and trained heating experts.

CAUTION!

A Daikin Altherma EHS(X/H) not put into operation properly can lead to damage to property and the environment.

• Observe the relevant regulations of technology to prevent creation of corrosion products and deposits. Minimum requirements regarding the quality of filling and supplementary water:
• Water hardness (calcium and magnesium, calculated as calcium carbonate): ≤slant mmol/l
• Conductivity: ≤500 (ideal ≤100) \$/cm
• Chloride: ≧250 mg/l

- The domestic water quality must comply with the EU Guideline 98/83 EC and the regionally-applicable regulations.

- During system operation, the water pressure at the pressure gauge must be checked at regular intervals. If necessary, readjust by refilling

5.1 Initial start-up

Read chapter 2.4 thoroughly before carrying out the steps described here.

After the Daikin Altherma EHS(X/H) was installed and connected completely, it will need to be undergo a one-time adaptation to the installation environment to be carried out by technical personnel (configuration).

After this configuration is complete, the installation is ready for operation and the operator can make additional custom configurations on it.

The heating specialist must instruct the operator [on using the machine], must prepare the commissioning report, and fill out the operating manual.

The settings of the optional components such the room thermostat or Daikin solar installation must be configured on the respective components themselves.

5.1.1 Requirements

• The Daikin Altherma EHS(X/H) is fully connected.
• The coolant system is dehumidified and filled with the specified amount of coolant.
• The heating and hot water systems are filled and charged at the right pressure (see chapter 7.4).
• The storage tank is filled up to the overflow (see chapter 7.3).
• Optional accessories have been mounted on and connected up.
  – The control valves of the heating system are open.

5.1.2 Start-up

• Turn power supply to Daikin Altherma EHS(X/H) on.
→ After the start phase, the operating language selector is displayed.
- Use the rotary switch to select the desired language.

The operating language can be changed again at any time.

• Confirm the changes with a brief push of the rotary switch.
  → The Daikin Altherma EHS(X/H) Basic Configuration is loaded.
  → The message "Starting Up" is displayed.
  → The message "Initialization" is displayed.
  → The standard display for the current rotary switch setting is displayed.

5.1.3 Set the commissioning parameters

5.1.4 Venting the hydraulics

If the storage temperature falls below a certain minimum value, the safety settings of the Daikin Altherma EHS(X/H) prevent the operation of the heat pump in the case of low external temperatures:

• External temperature < -2^ , minimum storage temperature = 30^
• External temperature < 12^ C ,minimum storage temperature = 23^ C .

Without backup-heater:

The storage tank water must be heated to the minimum required storage temperature by an external heater.

With Backup-Heater (EKBUxx):

With an outdoor temperature < 12^ and a storage tank temperature < 35^ , the Backup-Heater (BUH) is switched on automatically on in order to heat up the storage tank water to at least 35^ .

- In order to accelerate the heating process with the back-up heater, temporarily

• Set parameter [Function Heating] = "1" and
• Set parameter [Power DHW] to the maximum value of the back-up heater.
• Switch the rotary switch to operating mode and set the parameter [1x Hot Water] to "On". Following successful heating, reset the parameters to "Off".

- Make sure that the cap on the automatic venting unit is open (fig. 5-3, item A).

Technical line drawing of a mechanical assembly with pipes and housing (no text or symbols)

Fig. 5-3 Cap on the automatic venting unit

• Fit a hose to the manual venting valve (fig. 5-4, item B) and direct the hose away from the device. Open the valve until water comes out.
• Fit a hose to the second manual venting valve (fig. 5-4, item C) and open until water comes out.
• Activate the venting function (see FA RoCon HP).

By activating the Air Purge the RoCon HP control unit starts a defined sequence program with Start-Stopp operation of the integrated heat circulation pump and various settings for the 3-way diverter valve integrated into the Daikin Altherma EHS(X/H).

Existing air can leak from the automatic venting valve during the venting function and the hydraulic circuit connected to the Daikin Altherma EHS(X/H) is evacuated.

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

Prior to activating this function, the heating circuit must be completely filled.

• Check the water pressure and top up with water if necessary (see chapter 7.4).
• Repeat the venting, checking and topping-up process until: a) venting is complete. b) adequate water pressure is generated.

Technical diagram of a mechanical assembly with labeled parts B and C, showing fluid flow direction indicated by arrows.

Fig. 5-4 Manual venting valves

5.1.5 Check the minimum flow rate

The minimum flow must be checked with a closed heating circuit.

If the minimum flow is too low, an error message may appear and the heating system may shut down.

If the minimum flow is insufficient:

– there may be air in the circulation pump.

→ Vent the circulation pump.

- the valve drive of the 3-way diverter valve (3UVB1 / 3UV DHW) is defective.

→ Check the function of the valve drive, if necessary, replace valve drive.

• Close valves and actuators of all closed heat distribution circuits.
• Set "Heating" operating mode on the control unit of the Daikin Altherma EHS(X/H).
• Read info parameter [Flow Rate].
  → The flow rate must be at least 600 l/h (see operating manual of the control unit).

The Daikin Altherma EHS(X/H) controller permanently monitors the flow of the internal heat exchanger circuit. Various different minimum flow rates are required depending on the active operating mode:

• Operating mode "Heating": 600 l/h
• Operating mode "Cooling": 840 l/h
• Automatic defrosting function ( ) active: 1020 l/h

If, at a flow rate in excess of 600 l/h, an error message concerning inadequate minimum flow is displayed, you must check the actual flow rate in the active operating mode and rectify any possible causes of the error.

5.1.6 Configuring Screed Program parameters (only if necessary)

With the Screed Program the flow temperature is controlled on the basis of a pre-set temperature profile.

Further information on the Screed Program, its activation and expiry, see the operating manual of the control unit.

After expiry of the Screed Program the RoCon HP control unit continues to operate in the previously set operating mode. Unless configured previously, the following tasks need to be carried out in conclusion.

a) When connecting without a room station EHS157034:
- Set the heating characteristic curve or the desired flow temperature.

b) When connecting with a room station EHS157034:

• Activate the room station.
• Set the heating characteristic curve or the desired flow temperature. If required, activate the parameter [Room Influence] and set the preset room temperature.

5.2 Re-commissioning

5.2.1 Requirements

CAUTION!

Commissioning in frosty conditions can result in damage to the entire heating system.

- Only commission at temperatures below 0 °C when a water temperature of at least 5 °C can be guaranteed in the heating system and storage tank. Daikin recommends that you avoid operating the system in extremely frosty conditions.

– The Daikin Altherma EHS(X/H) is fully connected.
- The coolant system is dehumidified and filled with the specified amount of coolant.
– The heating and hot water systems are filled and charged at the right pressure (see chapter 7.4).
- The storage tank is filled up to the overflow (see chapter 7.3).

5.2.2 Start-up

If the storage temperature falls below a certain minimum value, the safety settings of the Daikin Altherma EHS(X/H) prevent the operation of the heat pump in the case of low external temperatures:

- External temperature < -2^ , minimum storage temperature = 30^ - External temperature < 12^ , minimum storage temperature = 23^ .

Without backup-heater:

The storage tank water must be heated to the minimum required storage temperature by an external heater.

With Backup-Heater (EKBUxx):

With an outdoor temperature < 12^ and a storage tank temperature < 35^ , the Backup-Heater (BUH) is switched on automatically on in order to heat up the storage tank water to at least 35^ .

- In order to accelerate the heating process with the back-up heater, temporarily

• Set parameter [Function Heating] = "1" and
• Set parameter [Power DHW] to the maximum value of the back-up heater.

• Switch the rotary switch to operating mode and set the parameter [1x Hot Water] to "On". Following successful heating, reset the parameters to "Off".

• Check the cold water connection and where necessary, fill the potable water heat exchanger.

• Turn power supply to Daikin Altherma EHS(X/H) on.
• Wait for the start phase.
• After the start phase has completed, in heating mode, vent the heating system, check the system pressure and adjust if necessary (max. 3 bar, see chapter 7.4).

• Carry out a visual inspection for leaks on all joints internally. Seal any leaks that occur in a professional manner.

• Set the dial on the controller to the required operating mode.

• If a Daikin solar system is connected, commission this in accordance with instructions provided. After disconnecting the Daikin solar system, check the level in the buffer storage tank once again.

6 Decommissioning

WARNING!

Danger of scalding and flooding when opening the solar return flow coupling or heating and hot water pipes due to escaping hot water.

• Only drain the storage tank container or heating system
  – when they have been left to cool sufficiently,
  – with a suitable device for the safe draining or catching of escaping water,
• wearing appropriate protective clothing.

6.1 Temporary shutdown

CAUTION!

A heating system which is shut down can freeze in the event of frost and may suffer damage.

• If there is any risk of frost, drain any water from the decommissioned heating system.
• If the heating system is not drained and there is a risk of frost, the power supplies must be secured and the external main switch must remain switched on.

If the Daikin Altherma EHS(X/H) is not needed for a long time, it can be temporarily decommissioned.

Daikin therefore recommends that you do not disconnect the system from power supply, but rather only place it in "Stand-By Mode" (consult the operating manual for the control system).

The system is then protected from frost. The pumps and valve protection functions are active.

If it is not possible to guarantee the power supply when there is danger of frost,

– completely discharge the Daikin Altherma EHS(X/H) on the water side, or
- suitable antifreeze measures must be taken for the connected heating system and hot water storage tank (e.g. draining).

If there is a danger of frost and the power supply cannot be guaranteed for just a few days, the unit's excellent heat insulation means that the Daikin Altherma EHS(X/H) does not have to be drained, provided that the storage tank temperature is monitored regularly and does not fall below +3 °C.

However, this does not provide frost protection for the connected heat distribution system.

6.1.1 Draining the storage tank

• Disconnect the Daikin Altherma EHS(X/H) from the power supply.
• Connect the outlet hose to the KFE filling connection (accessory KFE BA) (fig. 6-1, item A) and run to a drainage point that is at least soil deep.

If no KFE filling connection is available, the connection piece (fig. 6-1, item C) can alternatively be removed from the safety overflow (fig. 6-1, item B) and used.

Once the drainage process is complete, this must be replaced before the heating system can be started again.

7 Service and maintenance

7.1 General

Regular inspection and maintenance of the Altherma EHS(X/H) reduces energy consumption and ensures a long life and smooth operation.

RISK OF ENVIRONMENTAL DAMAGE!

Important information regarding the coolant used.

The entire heat pump system contains refrigerant with fluoridated greenhouse gases which damage the environment if released.

Coolant type: R410A

GWP* value: 2087,5

* GWP = Global Warming Potential

• Fill in the total coolant filling quantity on the supplied lable on the heat pump exterior unit (for information consult the installation instructions for the heat pump exterior unit).
• Never allow coolant to be released into the atmosphere - always suction it off and recycle using a suitable recycling device.

Have the inspection and maintenance carried out by authorised and trained HVAC engineers once a year, ideally before the heating period. This can prevent faults during the heating period.

Daikin recommends an inspection and maintenance contract to ensure regular inspection and maintenance.

Legal requirements

According to the F-Gases Directive (EC) No. 842/2006 Article 3, replaced on 01.01.2015 by (EC) No. 517/2014 Articles 3 and 4, Operators (or Owners) must perform regular maintenance on their fixed cooling systems, check impermeability and have any leaks repaired immediately.

All installation, maintenance and repair work on the cooling circuit must be documented e.g. in the operating manual.

Operators of Daikin heat pump systems are subject to the following obligations:

The European statutory investigation period applies for heat pumps from a total system coolant filling quantity of 3 kg or, as of 01.01.2017 from a total filling quantity of 5 t CO _2 -equivalent (in the case of R410A from 2.4 kg).

Daikin nonetheless recommends the conclusion of a maintenance contract, including documentation of the work carried out in the operating manual in order to preserve the right to guarantee, including for systems for which there is not legal obligation to monitor impermeability.

• With a system coolant total filling quantity of 3 kg – 30 kg or from 6 kg in hermetic systems and from 01.01.2017 with a total filling quantity of 5-50 t CO 2 -equivalent or from 10 t CO 2 -equivalent in hermetic systems:

7.2 Activities to be performed annually

WARNING!

Improperly carried out work on the Daikin Altherma EHS(X/H) and its components that have been connected as an option can endanger human life and health and adversely affect the operation of the these components.

- Work on the Daikin Altherma EHS(X/H) (such as maintenance or servicing) is only to be carried out by persons who are authorised and who have successfully completed qualifying technical or vocational training and who have taken part in advanced training sessions recognised by the appropriate responsible authorities. These include in particular certified heating engineers, qualified electricians and HVAC specialists, who because of their professional training and expert knowledge, have experience in the professional installation and maintenance of heating, cooling and air conditioning systems and heat pumps.

WARNING!

The gaseous coolant is heavier than air. In pits or in badly ventilated rooms it can collect in high concentrations. Breathing in high concentrations of gaseous coolant leads to feelings of faintness and suffocation. Toxic gases can be formed if gaseous coolants come into contact with open fire or hot objects.

• When working on the refrigerant circuit, ensure that the workplace is well ventilated.
• If necessary, before starting work, evacuate the coolant system completely.
• Never carry out work on the refrigerant circuit in closed rooms or work pits.
• Do not let refrigerant come into contact with open fire, embers or hot objects.
• Never allow coolant to escape into the atmosphere (forms high concentrations).
• After removing the service pipes from the filling connections, carry out a leakproof test on the refrigeration system. coolant can escape through leaks.

WARNING!

At normal atmospheric pressure and ambient temperatures, liquid coolant vaporises so suddenly that on contact with skin or eyes it can cause the tissue to freeze (danger of going blind).

• Always wear safety goggles and protective gloves.
• Never allow refrigerant to escape into the atmosphere (high pressure at the point of the leak).
• When removing the service pipes from the filling connections, never hold the connections in the direction of your body. Residual refrigerant could escape.

WARNING!

Under the cover of the Daikin Altherma EHS(X/H) temperatures of up to 90 °C can arise during operation. During operation, hot water temperatures > 60 °C arise.

• Touching components during or after operation leads to a risk of burns.
  – Water discharged during maintenance and servicing work can cause scalding on contact with the skin.
• Before carrying out servicing and maintenance work, allow the Daikin Altherma EHS(X/H) to cool down sufficiently.
• Wear protective gloves.

WARNING!

Live parts can cause an electric shock on contact and cause fatal burns and injuries.

• Before beginning work on live parts, disconnect all of the systems circuits from the power supply (switch off main switch, disconnect fuse) and secure against unintentional restart.

8.4 Monitoring and configuration DIP Switch

WARNING!

Touching live parts can result in an electric shock and lead to potentially fatal injuries and burns.

- Before beginning work on live parts, disconnect all of the systems circuits from the power supply (switch off main switch, disconnect fuse) and secure against unintentional restart. Means with contact separation in all poles that provide full disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.

• Disconnect the system from the power supply.
• Open the control housing and remove the RoCon BM1 board (see chapter 4.5.7).
• Check the DIP switch setting on the A1P circuit board of the Daikin Altherma EHS(X/H), adjust where necessary (see tab. 8-4).
  The factory preset may only be changed if e.g. an optional accessory was connected.
• Replace the RoCon BM1 switch board, close the control housing and reconnect the power supply.

DIP switch settings are not recognised until a brief interruption to the power supply.

* If you intend to run the internal heating circulation pump continuously, it will need to be connected to the circuit board A1P, plug X17A, via a separate connection cable (E1400132).
Tab. 8-4 DIP switch settings

8.5 Emergency operation

In the case of incorrect setting in the electronic control system, emergency heating operation can be maintained by activating the special "Manual Operation" function on the control unit (see operating manual for the control unit).

If the 3-way valves are intact, the Daikin Altherma EHS(X/H) switches to Heating mode. The necessary flow temperature can be adjusted with the rotary switch.

9 Hydraulic system connection

WARNING!

High temperatures can occur in the solar storage tank. Therefore, sufficient scalding protection must be included when the hot water system is installed (automatic hot water mixing device).

The Daikin units can also be optionally fitted with gravity breaks made of plastic to prevent thermal losses caused by gravity flow. These are suitable for operating temperatures of maximum 95 °C and for fitting in all tank-side heat exchanger connections (except heat exchangers for pressurised solar tank charging).

The customer must install suitable circulation brakes for components connected to the heat exchanger for pressurised solar tank charging.

A selection of diagrams of the most common systems is shown below. The arrangements shown are only examples, and are no substitute for careful system planning. For more diagrams and further information about the electrical connection please see the Daikin homepage.
