The electric immersion heater is only used if the boiler delivers a fault status
message or if it has been shut down via boiler lock. This means that in normal
situations the DHW is heated by the boiler.
Summer
The electric immersion heater is used as soon as all connected heating circuits
have switched to summer operation. The DHW is again heated by the boiler as
soon as at least one of the heating circuits has switched back to heating mode. But
the electric immersion heater is also used if the boiler delivers a fault status
message or has been shut down via boiler lock.
Always
DHW is heated with the electric immersion heater throughout the year. When using
this setting, an electric immersion heater must be available. The boiler does not
