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.

the user interface will display error 7H‑01. After some time,
this error will reset automatically and the unit will resume
operation.
INFORMATION
Error AJ-03 is reset automatically from the moment there is
a normal tank heat-up.
