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 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,
will appear on the user interface.
Possible cause
Heat pump is damaged.
INFORMATION
When the backup heater takes over the heat load,
electricity consumption will be considerably higher.

Symptom: The system is making
gurgling noises after
commissioning
Possible cause
There is air in the system.
Incorrect hydraulic balance.
Various malfunctions.
(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 an error
or
is displayed on the home pages 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.
