INFORMATION
In case of error code AH and no interruption of the
disinfection function occurred due to domestic hot water
tapping, following actions are recommended:
▪ When the Domestic hot water > Type > Reheat or
Reheat + sched. is selected, it is recommended to
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 by 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.
NOTICE
When the minimum water flow is lower than described in
the table below, the unit will temporarily stop operation and
the user interface will display error 7H‑01. After some time,
this error will reset automatically and the unit will resume
operation.
Minimum required flow during heat pump operation
04 models Heating 6l/min
Cooling 6l/min
08 models Heating 6l/min
Cooling 10l/min
11 models Heating 10l/min
Cooling 15l/min
16 models Heating 10l/min

All models 12l/min
If the 7H‑01 error persists, the unit will stop operation and the user
interface will display an error code that needs to be reset manually.
