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

booster mode. However, this
consumes extra energy. See
"3.4.5 Using the DHW tank
booster mode"
If you can wait, overrule
(increase) the active or next
scheduled desired temperature
so that more hot water will be
produced exceptionally. See
If the problem recurs daily, do
one of the following:
▪ Increase
the
DHW
tank
temperature preset value. See
the user reference guide.
▪ Adjust
the
DHW
tank
temperature
schedule.
Example:
Program

additionally
heat
up
the
DHW tank to a preset value
(

See
The desired DHW tank
temperature is too low.

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
Corrective action
Heat pump is damaged.
▪ Press
to view a description
of the problem.
▪ Press
again.
▪ Select
to allow the backup
heater to take over the heat
load.
▪ Call your local dealer to get
the heat pump fixed.
INFORMATION
When the backup heater takes over the heat load,
electricity consumption will be considerably higher.
