Setting the space operation mode
The leaving water is the water that is sent to the heat
emitters. The desired leaving water temperature is set by
your installer in accordance with the heat emitter type.
Example: A home screen is available for both temperature
zones: the main zone and the additional zone. You only
have to adjust the leaving water temperature settings in
case of problems.
About space operation modes
The heat pump is a heating only model. The system can heat up a
space, but NOT cool down a space.

Scheduled + reheat mode
In scheduled + reheat mode ( ), the domestic hot water control is
the same as in scheduled mode. However, when the DHW tank
temperature drops below a preset value (=reheat tank temperature –
hysteresis value; example: 35°C), the DHW tank 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.

Overview: Maintenance and

Symptom: You are feeling too cold
(hot) in your living room
The installer has to perform a yearly maintenance. You can find the
contact/helpdesk number via the user interface.
As end user, you have to:
Possible cause

too low (high).
room temperature.
▪ Keep the area around the unit clean.
▪ Keep the user interface clean with a soft damp cloth. Do NOT use
any detergents.
If the problem recurs daily, do
one of the following:
Refrigerant
▪ Increase (decrease) the room
temperature preset value.
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
▪ Adjust the room temperature
schedule.
Refrigerant type: R410A
Global warming potential (GWP) value: 2087.5
The desired room temperature
cannot be reached.
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes
CO2-equivalent) is used to determine the maintenance
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
6.2
Symptom: The water at the tap is
too cold
Possible cause
Please contact your installer for more information.
WARNING
The desired DHW tank
temperature is too low.
If you immediately need domestic
hot water, activate the DHW tank
booster mode. However, this
consumes extra energy.
If you can wait, overrule
(increase) the active or next
scheduled desired temperature
so that more hot water will be
produced exceptionally.
Turn off any combustible heating devices, ventilate the
room and contact the dealer where you purchased the unit.
Do not use the system until a service person confirms that
the portion where the refrigerant leaks is repaired.
If the problems recurs daily, do
one of the following:
▪ Increase the DHW tank
temperature preset value.
To find the contact/helpdesk
number
▪ Adjust
the
DHW tank
temperature
schedule.
Example:
Program
to
additionally heat up the
DHW tank to a preset value
(Storage eco = lower tank
temperature) during the day.
Prerequisite: You switched the permission level to Advanced end
user.

Corrective action
You ran out of domestic hot
water because of unusual high
consumption.
The refrigerant in the system is safe and normally does not
leak. If the refrigerant leaks in the room, contact with a fire
of a burner, a heater or a cooker may result in a harmful
gas.

Increase the desired leaving
water temperature in accordance
with the heat emitter type.
Go to [6.3.2]:
> Information > Error handling > Contact/
helpdesk number.
6.3
Symptom: Heat pump failure
When the heat pump fails to operate, the backup heater can serve
as an emergency heater and either automatically or nonautomatically take over the heat load.
▪ When auto emergency is activated and a heat pump failure
occurs, the backup heater will automatically take over the heat
load.
▪ When auto emergency is not activated and a heat pump failure
occurs, the domestic hot water and space heating operations will
stop and need to be recovered manually. The user interface will
then ask you to confirm whether the backup heater can take over
the heat load or not.
When the heat pump fails,
