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.
