2.2 Instructions for safe operation

WARNING: MILDLY FLAMMABLE MATERIAL

The refrigerant inside this unit is mildly flammable.

WARNING

The appliance shall be stored so as to prevent mechanical damage and in a well-ventilated room without continuously operating ignition sources (example: open flames, an operating gas appliance or an operating electric heater).

WARNING

• Do NOT pierce or burn refrigerant cycle parts.
• Do NOT use cleaning materials or means to accelerate the defrosting process other than those recommended by the manufacturer.
• Be aware that the refrigerant inside the system is odourless.

WARNING

The refrigerant inside the unit is mildly flammable, but normally does NOT leak. If the refrigerant leaks in the room and comes in contact with fire from a burner, a heater, or a cooker, this may result in fire, or the formation of a harmful gas.

Turn off any combustible heating devices, ventilate the room, and contact the dealer where you purchased the unit.

Do NOT use the unit until a service person confirms that the part from which the refrigerant leaked has been repaired.

WARNING

Air purging heat emitters or collectors. Before you purge air from heat emitters or collectors, check if 🙏 or 🕒 displayed on the home screen of the user interface.

• If not, you can purge air immediately.
• If yes, make sure that the room where you want to purge air is sufficiently ventilated. Reason: Refrigerant might leak into the water circuit, and subsequently into the room when you purge air from the heat emitters or collectors.

3 About the system

Depending on the system layout, the system can:

• Heat up a space
• Cool down a space (if a heating/cooling heat pump model is installed)

5.7 Domestic hot water control

5.7.1 About domestic hot water control

Depending on the DHW tank mode (installer setting), you use a different domestic hot water control:

• Reheat only
• Scheduled reheat

INFORMATION

In case of error code AH and no interruption of the disinfection function occurred due to domestic hot water tapping, following actions are recommended:

- It is recommended to program the start-up of the disinfection function at least 4 hours later than the last expected large hot water tapping. This start-up can be set by installer settings (disinfection function).

When weather-dependent operation is used for the tank, the tank temperature is determined automatically by the outdoor temperature. For more information, see "5.9 Weather-dependent curve" [▶ 43].

To determine which domestic hot water mode you are using (method 1)

Check the installer settings table filled in by the installer.

To determine which domestic hot water mode you are using (method 2)

5.7.2 Reheat mode

In reheat mode the storage tank continuously heats up to the temperature shown on the home screen (example: 50^ C) when the temperature drops below a certain value.

T_t Storage tank temperature t Time

INFORMATION

Risk of space heating capacity shortage: In case of frequent tank operation, frequent and long space heating/cooling interruption will happen when selecting the following:

Tank > Heat up mode > Reheat only.

5.7.3 Scheduled reheat mode

In scheduled reheat mode the storage tank set temperature varies according to the schedule. When the tank temperature drops below the set temperature minus the heat pump ON hysteresis temperature [6-00], the tank heats up to the reheat temperature.

Example:

T_t Storage tank temperature t Time

• At 14:00 the DHW schedule is programmed to heat up the tank to 60^ .
• At 21:00 the DHW schedule is programmed to heat up the tank to 50^ . This value is valid until 14:00 the next day.
• With the higher set temperature, in the afternoon and evening more hot water is available.
• During the morning, you consume hot water and the storage tank temperature decreases.
• When the tank temperature drops below a preset value (=set temperature – hysteresis value; example 40°C), the tank is heated up to 50°C.
• During the afternoon and evening, you consume hot water again and the DHW tank temperature decreases again.
• When the tank temperature drops below a preset value (=set temperature – hysteresis value; example 50°C), the tank is heated up to 60°C.

5.7.4 To change the domestic hot water temperature

In Reheat only mode, you can use the tank temperature setpoint screen to read out and adjust the domestic hot water temperature.

1 Go to [5]: Tank.	[IMAGE]
2 Adjust the domestic hot water temperature.	a Actual domestic hot water temperatureb Desired domestic hot water temperature

In other modes, you can only view the setpoint screen but not modify it.

When weather-dependent operation is used for the tank, the tank temperature is determined automatically by the outdoor temperature. For more information, see "5.9 Weather-dependent curve" [43].

5.7.5 Using DHW powerful operation

About powerful operation

Powerful operation allows the domestic hot water to be heated by the backup heater or booster heater. Use this mode on days when there is more hot water usage than usual.

To check if powerful operation is active

If is displayed on the home screen, powerful operation is active.

Activate or deactivate Powerful operation as follows:

1 Go to [5.1]: Tank > Powerful operation	10...○
2 Turn powerful operation Off or On.	10...○

Usage example: You immediately need more hot water

You are in the following situation:

• You already consumed most of your domestic hot water.
• You cannot wait for the next scheduled action to heat up the domestic hot water tank.

Then you can activate powerful operation. The domestic hot water tank will start heating up the water to the Comfort temperature.

INFORMATION

When powerful operation is active, the risk of space heating/cooling and capacity shortage comfort problems is significant. In case of frequent domestic hot water operation, frequent and long space heating/cooling interruptions will happen.

5.8 Preset values and schedules

5.8.1 Using preset values

About preset values

For some settings in the system, you can define preset values. You only need to set these values one time, then reuse the values in other screens such as the scheduling screen. If you later want to change the value, you only have to do it in one place.

Possible preset values

You can set the following user-defined preset values:

Preset value Where used
Electricity prices under [7.5] User settings > Electricity priceRestriction: Only applicable if Bivalent is enabled by the installer.	[7.5.1] High You can	n use these preset values in [7.5.4] Schedule (weekly schedule screen for the energy prices).See "5.8.4 Setting the energy prices" [ ▶ 41].
	[7.5.2] Medium

5.9 Weather-dependent curve

5.9.1 What is a weather-dependent curve?

Weather-dependent operation

The unit operates 'weather dependent' if the desired leaving water or tank temperature is determined automatically by the outdoor temperature. It therefore is connected to a temperature sensor on the North wall of the building. If the outdoor temperature drops or rises, the unit compensates instantly. Thus, the unit does not have to wait for feedback by the thermostat to increase or decrease the temperature of the leaving water or tank. Because it reacts more quickly, it prevents high rises and drops of the indoor temperature and water temperature at tap points.

Advantage

Weather-dependent operation reduces energy consumption.

Weather-dependent curve

To be able to compensate for differences in temperature, the unit relies on its weather-dependent curve. This curve defines how much the temperature of the tank or leaving water must be at different outdoor temperatures. Because the slope of the curve depends on local circumstances such as climate and the insulation of the house, the curve can be adjusted by an installer or user.

Types of weather-dependent curve

There are 2 types of weather-dependent curves:

2-points curve
- Slope-offset curve

Which type of curve you use to make adjustments, depends on your personal preference. See "5.9.4 Using weather-dependent curves" [▶ 46].

Availability

The weather-dependent curve is available for:

• Main zone - Heating
• Main zone - Cooling
  ■ Additional zone - Heating
  ■ Additional zone - Cooling
• Tank (only available to installers)

INFORMATION

To operate weather dependent, correctly configure the setpoint of the main zone, additional zone or tank. See "5.9.4 Using weather-dependent curves" [▶ 46].

5.9.2 2-points curve

Define the weather-dependent curve with these two setpoints:

• Setpoint (X1, Y2)
• Setpoint (X2, Y1)

Example

Item Description

a Selected weather dependent zone:Main zone or additional zone heatingMain zone or additional zone coolingDomestic hot water

X1, X2 Examples of outdoor ambient temperature

Y1, Y2 Examples of desired tank temperature or leaving water temperature.The icon corresponds to the heat emitter for that zone:Underfloor heatingan coil unitRadiatorStorage tank

Possible actions on this screen
○⋯○	Go through the temperatures.
○⋯○	Change the temperature.
○⋯○	Go to the next temperature.
○⋯○	Confirm changes and proceed.

5.9.3 Slope-offset curve

Slope and offset

Define the weather-dependent curve by its slope and offset:

• Change the slope to differently increase or decrease the temperature of the leaving water for different ambient temperatures. For example, if leaving water temperature is in general fine but at low ambient temperatures too cold, raise the slope so that leaving water temperature is heated increasingly more at decreasingly lower ambient temperatures.
• Change the offset to equally increase or decrease the temperature of the leaving water for different ambient temperatures. For example, if leaving water temperature is always a bit too cold at different ambient temperatures, shift the offset up to equally increase the leaving water temperature for all ambient temperatures.

Examples

Weather-dependent curve when slope is selected:

Weather-dependent curve when offset is selected:

Item Description
a WD curve before changes.
b WD curve after changes (as example): ·When slope is changed, the new preferred temperature at X1 unequally higher than the preferred temperature at X2. ·When offset is changed, the new preferred temperature at X1 is equally higher as the preferred temperature at X2.
c Slope

To define the setpoint mode

To use the weather-dependent curve, you need to define the correct setpoint mode:

Go to setpoint mode ... Set the setpoint mode to ...
Main zone – Heating
[2.4] Main zone >Setpoint mode WD	heating, fixed cooling OR Weather dependent
Main zone – Cooling
[2.4] Main zone >Setpoint mode We	ather dependent
Additional zone – Heating
[3.4] Additional zone >Setpoint mode	WD heating, fixed cooling OR Weather dependent
Additional zone – Cooling
[3.4] Additional zone >Setpoint mode	Weather dependent
Tank
[5.B] Tank >Setpoint mode	Restriction: Only available to installers. Weather dependent

To change the type of weather-dependent curve

To change the type for all zones (main + additional) and for the tank, go to [2.E] Main zone >WD curve type.

Viewing which type is selected is also possible via:

• [3.C] Additional zone >WD curve type
• [5.E] Tank > WD curve type

Restriction: Only available to installers.

To change the weather-dependent curve

Zone Go to ...
Main zone – Heating	[2.5] Main zone > Heating WD curve
Main zone – Cooling	[2.6] Main zone > Cooling WD curve
Additional zone – Heating	[3.5] Additional zone > Heating WD curve
Additional zone – Cooling	[3.6] Additional zone > Cooling WD curve
Tank Restriction: Only available to installers.[5.C] Tank > WD curve

INFORMATION

Maximum and minimum setpoints

You cannot configure the curve with temperatures that are higher or lower than the set maximum and minimum setpoints for that zone or for the tank. When the maximum or minimum setpoint is reached, the curve flattens out.

To fine-tune the weather-dependent curve: slope-offset curve

The following table describes how to fine-tune the weather-dependent curve of a zone or tank:

You feel ... Fine-tune with slope and offset:
At regular outdoor temperatures ...	At cold outdoor temperatures ...	Slope Offset
OK Cold ↑ —
OK Hot ↓ —
Cold OK ↓ ↑
Cold Cold — ↑
Cold Hot ↓ ↑

6 Energy saving tips

Tips about room temperature

• Make sure the desired room temperature is NEVER too high (in heating mode) or too low (in cooling mode), but ALWAYS according to your actual needs. Each saved degree can save up to 6% of heating/cooling costs.
• Do NOT increase/decrease the desired room temperature to speed up space heating/cooling. The space will NOT heat up/cool down faster.
• When your system layout contains slow heat emitters (example: underfloor heating), avoid large fluctuation of the desired room temperature and do NOT let the room temperature drop too low/rise too high. It will take more time and energy to heat up/cool down the room again.
• Use a weekly schedule for your normal space heating or cooling needs. If necessary, you can easily deviate from the schedule:
• For shorter periods: You can overrule the scheduled room temperature until the next scheduled action. Example: When you have a party, or when you are leaving for a couple of hours.
• For longer periods: You can use the holiday mode.

Tips about leaving water temperature

• In heating mode, a lower desired leaving water temperature results in lower energy consumption and better performance. In cooling, the opposite is valid.
• Set the desired leaving water temperature in accordance with the heat emitter type. Example: Underfloor heating is designed for lower leaving water temperature than radiators and heat pump convectors.

Tips about DHW temperature

• Make sure the desired DHW temperature, reflected by storage tank temperature, is NOT too high. Example: After installation, lower the tank temperature daily by 1°C and check if you still have enough hot water.
• Program to turn ON the domestic hot water pump ONLY during periods of the day when instant hot water is necessary. Example: In the morning and evening.

7 Maintenance and service

7.1 Overview: Maintenance and service

The installer has to perform a yearly maintenance. You can find the contact/helpdesk number via the user interface.

8.3 Symptom: You are feeling too cold (hot) in your living room

Possible cause Corrective action
The desired room temperature is too low (high).	Increase (decrease) the desired room temperature. See "5.6.4 To change the desired room temperature" [▶ 29].If the problem recurs daily, do one of the following:▪ Increase (decrease) the room temperature preset value. See "5.8.1 Using preset values" [▶ 34].▪ Adjust the room temperature schedule. See "5.8.2 Using and programming schedules" [▶ 34] and "5.8.3 Schedule screen: Example" [▶ 37].
The desired room temperature cannot be reached.	Increase the desired leaving water temperature in accordance with the heat emitter type. See "5.6.5 To change the desired leaving water temperature" [▶ 29].
The weather-dependent curve is set incorrectly.	Adjust the weather-dependent curve.See "5.9 Weather-dependent curve" [▶ 43].

8.4 Symptom: The water at the tap is too cold

Possible cause Corrective action
You ran out of domestic hot water because of unusual high consumption.	If you immediately need domestic hot water, activate the tankPowerful operation. However, this consumes extra energy. See "5.7.5 Using DHW powerful operation" [▶ 33].If the problems recurs daily, do one of the following:Adjust the storage tank temperature schedule. See "5.8.2 Using and programming schedules" [▶ 34] and "5.8.3 Schedule screen:Example" [▶ 37].
The desired storage tank temperature is too low.

8.5 Symptom: Heat pump failure

When the heat pump fails to operate, the backup heater or boiler can serve as an emergency heater. It then takes over the heat load either automatically or by manual interaction.

• When Emergency is set to Automatic and a heat pump failure occurs, the backup heater or boiler automatically takes over the domestic hot water production and space heating.
• When Emergency is set to Manual and a heat pump failure occurs, the domestic hot water heating and space heating stops.

To manually recover it via the user interface, go to the Malfunctioning main menu screen and confirm whether the backup heater can take over the heat load or not.

■ Alternatively, when Emergency is set to:

• auto SH reduced/DHW on, space heating is reduced but domestic hot water is still available.
• auto SH reduced/DHW off, space heating is reduced and domestic hot water is NOT available.
• auto SH normal/DHW off, space heating operates as normally but domestic hot water is NOT available.

Similarly as in Manual mode, the unit can take the full load with the backup heater or boiler if the user activates this via the Malfunctioning main menu screen.

When the heat pump fails, or will appear on the user interface.

Possible cause Corrective action

Heat pump is damaged. See "8.1 To display the help text in case of a malfunction" [▶ 56].

INFORMATION

When the backup heater takes over the heat load, electricity consumption will be considerably higher.

8.6 Symptom: The system is making gurgling noises after commissioning

Possible cause Corrective action
There is air in the system.	Purge air from the system. ^(a)
Incorrect hydraulic balance.	To be performed by the installer:1 Perform hydraulic balancing to assure that the flow is correctly distributed between the emitters.2 If hydraulic balancing is not sufficient, change the pump limitation settings ([9-0D] and [9-0E] if applicable).
Various malfunctions.	Check iforisdisplayed on the home screen of the user interface. See "8.1 To display the help text in case of a malfunction" [▶ 56] for more information about the malfunction.

^[a] We recommend to purge air with the air purge function of the unit (to be performed by the installer). If you purge air from the heat emitters or collectors, mind the following:

WARNING

Air purging heat emitters or collectors. Before you purge air from heat emitters or collectors, check if or is displayed on the home screen of the user interface.

- If not, you can purge air immediately.

- If yes, make sure that the room where you want to purge air is sufficiently ventilated. Reason: Refrigerant might leak into the water circuit, and subsequently into the room when you purge air from the heat emitters or collectors.
