8.2 Symptom: The water at the tap is
too cold
Possible cause Corrective action
Your tank 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.
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
(Storage eco = lower tank
temperature) during the day.
The desired DHW tank
temperature is too low.
The instant DHW temperature is
too low. (Only applicable when
no tank is installed). Increase the instant DHW set
point temperature.
8.3 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 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 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.
8.4 Symptom: The system is making
gurgling noises after
commissioning
Possible cause Corrective action

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.
