Symptom 5: The water pressure relief valve leaks
P
OSSIBLE CAUSES
Dirt is blocking the water pressure
relief valve outlet.
Symptom 6: The user interface displays "n
certain buttons
P
OSSIBLE CAUSES
The current permission level is set to

P
OSSIBLE CAUSES
Backup heater operation is not
activated.
The backup heater equilibrium
temperature has not been
configured correctly.
Too much heat pump capacity is
used for heating domestic hot water
(applies only to installations with a
domestic hot water tank).
Symptom 8: Temperature values displayed on the remote controller (user
interface) are displayed in °F instead of °C
P
OSSIBLE CAUSES
You accidentally changed the setting
