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 from which you purchased
the unit.
Do not use the unit until a service person confirms that the
portion from which the refrigerant leaked is repaired.

6.2 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.
If the problem recurs daily, do
one of the following:
▪ Increase (decrease) the room
temperature preset value.
▪ Adjust the room temperature
schedule.
The desired room temperature
cannot be reached. Increase the desired leaving
water temperature in accordance
with the heat emitter type.
6.3 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 DHW tank
Powerful operation. 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.
If the problems recurs daily, do
one of the following:
▪ Increase the DHW tank
temperature preset value.
▪ Adjust the DHW tank
temperature schedule.
Example: Program to
additionally heat up the
DHW tank to a preset value
(Eco setpoint = lower tank
temperature) during the day.
The desired DHW tank
temperature is too low.
6.4 Symptom: Heat pump failure
When the heat pump fails to operate, the optional backup heater and
anti-legionella 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 optional backup heater will automatically take over the
heat load, and the anti-legionella heater will automatically take
over 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. The user interface will
then ask you to confirm whether the optional backup heater or
anti-legionella heater can take over the heat load or not.
When the heat pump fails, or will appear on the user
interface.
Possible cause Corrective action
Heat pump is damaged. See "6.1 To display the help text
in case of a malfunction" on
page 11
.
INFORMATION
When the backup heater or anti-legionella heater takes
over the heat load, electricity consumption will be
considerably higher.
