CAUTION
The backup heater permission schedule is used to restrict or allow backup heater
operation based on a weekly program. Advice: In order to avoid unsuccessful
disinfection function, at least allow the backup heater (by the weekly program) for
minimum 4 hours starting from the scheduled start-up of disinfection. If the backup
heater is restricted during disinfection, this function will NOT be successful and the
applicable warning AH will be generated.
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:
▪ When the Reheat only or Schedule + reheat mode is selected, it is
recommended to program the start-up of the disinfection function at least
4hours later than the last expected large hot water tapping. This start-up can be
set by installer settings (disinfection function).
▪ When the Schedule only mode is selected, it is recommended to program an
Eco action 3 hours before the scheduled start-up of the disinfection function to
preheat the tank.

4.5.3 Scheduled mode
TtDHWtank temperature
t Time
In scheduled mode the DHWtank produces hot water corresponding to a schedule.
The best time to allow the tank to produce hot water is at night, because the space
heating demand is lower.
Example:
TtDHWtank temperature
▪ Initially, the DHW tank temperature is the same as the temperature of the
domestic water entering the DHWtank (example: 15°C).
▪ At 00:00 the DHW tank is programmed to heat up the water to a preset value
(example: Comfort = 60°C).
▪ During the morning, you consume hot water and the DHW tank temperature
decreases.
▪ At 14:00 the DHW tank is programmed to heat up the water to a preset value
(example: Eco = 50°C). Hot water is available again.
▪ During the afternoon and evening, you consume hot water again and the
DHWtank temperature decreases again.
▪ At 00:00 the next day, the cycle repeats.
4.5.4 Scheduled + reheat mode
In scheduled + reheat mode, the domestic hot water control is the same as in
scheduled mode. However, when the DHWtank temperature drops below a preset
value (=reheat tank temperature – hysteresis value; example: 35°C), the DHWtank
heats up until it reaches the reheat set point (example: 45°C). This ensures that a
minimum amount of hot water is available at all times.

4.8 Weather-dependent curve
4.8.1 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
4 | Operation
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 "4.8.4Using weather-dependent curves"[438].
Availability
The weather-dependent curve is available for:
▪ Main zone - Heating
▪ Main zone - Cooling
▪ Additional zone - Heating

4.8.3 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.

▪ : Fan coil unit
▪ : Radiator
▪ : Domestic hot water tank
Possible actions on this screen

Change the temperature.
Go to the next temperature.
Confirm changes and proceed.

▪ 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.

5 Energy saving tips
Tips about room temperature
▪ Make sure the desired room temperature is NEVER too high, but ALWAYS
according to your actual needs. Each saved degree can save up to 6% of heating
costs.
▪ Do NOT increase the desired room temperature to speed up space heating. The
space will NOT heat up faster.
▪ When your system layout contains slow heat emitters (example: under floor
heating), avoid large fluctuation of the desired room temperature and do NOT let
the room temperature drop too low. It will take more time and energy to heat up
the room again.
▪ Use a weekly schedule for your normal space heating 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.
5 | Energy saving tips
Tips about leaving water temperature
▪ In heating mode, a lower desired leaving water temperature results in lower
energy consumption and better performance.
▪ 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 heatpump convectors.
Tips about DHWtank temperature
▪ Use a weekly schedule for your normal domestic hot water needs (only in
scheduled mode).
- Program to heat up the DHW tank to a preset value (Comfort = higher
DHWtank temperature) during the night, because then space heating demand
is lower.
- If heating up the DHW tank once at night is not sufficient, program to
additionally heat up the DHWtank to a preset value (Eco = lower DHW tank
temperature) during the day.
▪ Make sure the desired DHW tank temperature is NOT too high. Example: After
installation, lower the DHWtank 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.

6.1 Overview: Maintenance and service
The installer has to perform a yearly maintenance. You can find the contact/
helpdesk number via the user interface.
As enduser, you have to:
▪ Keep the area around the unit clean.
▪ Keep the user interface clean with a soft damp cloth. Do NOT use any detergents.
Refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent gases into the
atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO2 equivalent.
Formula to calculate the quantity in CO2 equivalent tonnes: GWP value of the
refrigerant × total refrigerant charge [in kg] / 1000
Please contact your installer for more information.
WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
WARNING
The appliance shall be stored in a 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.

For the symptoms listed below, you can try to solve the problem yourself. For any
other problem, contact your installer. You can find the contact/helpdesk number
via the user interface.
In case of a malfunction, the following will appear on the home screen depending
on the severity:
▪ : Error
▪ : Malfunction
You can get a short and a long description of the malfunction as follows:
1 Press the left dial to open the main menu and go to
Malfunctioning.
Result: A short description of the error and the error code is
displayed on the screen.
2 Press in the error screen.
Result: A long description of the error is displayed on the
screen.

Conditions: The user permission level is set to advanced end user.
1 Go to [8.2]: Information > Malfunction history.
You see a list of the most recent malfunctions.
7.3 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 "4.4.4To change the
desired room temperature"[419].
If the problem recurs daily, do one of
the following:
User reference guide
46
▪ Increase (decrease) the room
temperature preset value. See
"4.7.1Using preset values"[427].
▪ Adjust the room temperature
schedule. See "4.7.3 Using and

See Weather dependent operation.
7.4 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.
The desired DHWtank temperature is
too low.
If you immediately need domestic hot
water, activate the DHW tank
Powerful operation. However, this
consumes extra energy. See
"4.5.6Using DHW powerful
operation"[423].
If the problems recurs daily, do one of
the following:
▪ Increase the DHW tank temperature
preset value. See "4.7.1 Using preset
values"[427].
7.5 Symptom: Heat pump failure
When the heat pump fails to operate, the backup heater can serve as an
emergency heater and either automatically or non-automatically take over the
heat load.
▪ When auto emergency is set to Automatic and a heat pump failure occurs, the
backup heater will automatically take over the heat load and the domestic hot
water production.
▪ When auto emergency is set to Manual and a heat pump failure occurs, the
domestic hot water and space heating operation will stop and need to be
recovered manually via the user interface. To recover operation manually, go to
the Malfunctioning main menu screen, where the user interface will then ask
you to confirm whether the backup heater can take over the heat load or not.
▪ Adjust the DHW tank temperature
schedule. Example: Program to
additionally heat up the DHWtank to
a preset value (Eco setpoint =
lower tank temperature) during the
day. See "4.7.3 Using and
programming schedules" [4 30] and
"4.7.4 Schedule screen:
Example"[431].
