9.5 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
booster mode. However, this
consumes extra energy.

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
(Storage eco = lower tank
temperature) during the day.
The desired DHWtank
temperature is too low.
9.6 Symptom: Heat pump failure
When the heat pump fails to operate the gas boiler can serve as an
emergency back-up heater and either automatically or non-
automatically take over the entire heat load. When auto emergency
is activated and a heat pump failure occurs, the boiler will
automatically take over the heat load. When a heat pump failure
occurs and auto emergency is not activated, 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
boiler can take over the entire heat load or not. When the heat pump
fails, will appear on the user interface.
Possible cause Corrective action
Heat pump is damaged. ▪ Press to view a description
of the problem.
▪ Press again.
▪ Select to allow the gas
boiler to take over the entire
heat load.
▪ Call your local dealer to get
the heat pump fixed.
INFORMATION
When the gas boiler takes over the entire heat load, gas
consumption will be considerably higher.
