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
Schedule + 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
Eco
action 3 hours before the scheduled start-up of the disinfection function to
preheat the tank.
When weather-dependent operation is used for the tank, the tank temperature is
determined automatically by the outdoor temperature. For more information, see
