Possible causes Corrective action
There is air in the system. Purge air manually or automatically. See
the air purge function in the
"Commissioning" chapter.
Too much heat pump capacity is used
for heating domestic hot water (applies
only to installations with a domestic hot
water tank)
Check and make sure that the "space
heating priority" settings have been
configured appropriately:
▪ Make sure that the "space heating
priority status" has been enabled. Go
to [A.8] > Installer settings >
Overview settings [5‑02]
▪ Increase the "space heating priority
temperature" to activate backup
heater operation at a higher outdoor
temperature. Go to [A.8] >
Installer settings > Overview
settings [5‑03]
13.3.7 Symptom: The pressure at the tapping point is temporarily unusually high
Possible causes Corrective action
Failing or blocked pressure relief valve. ▪ Flush and clean the complete tank
including the piping between pressure
relief valve and the cold water inlet.
▪ Replace the pressure relief valve.
13.3.8 Symptom: Tank disinfection function is NOT completed correctly (AH-error)
Possible causes Corrective action
The disinfection function was
interrupted by domestic hot water
tapping
Program the start-up of the disinfection
function when the coming 4hours NO
domestic hot water tapping is expected.
Large domestic hot water tapping
happened recently before the
programmed start-up of the disinfection
function
When the Domestic hot water >
Type > Reheat or Reheat + sched.

program the start-up of the disinfection
function at least 4hours later than the
last expected large hot water tapping.
This start-up can be set via the installer
settings (disinfection function).
When the Domestic hot water >
Type > Scheduled only is selected,
it is recommended to program a
Storage eco 3hours before the
scheduled start-up of the disinfection
function to preheat the tank.
