About domestic hot water control
Depending on the DHW tank mode (installer setting), you use a
different domestic hot water control:
▪
Reheat only
▪
Sc reheat
▪
Schedule only
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
Reheat only
or
Sc reheat
mode
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
Schedule only
mode is selected, it is
recommended to program an

the scheduled start-up of the disinfection function to
preheat the tank.
