5051 Storage tank temp max
The DHW storage tank is charged by solar energy to the set maximum DHW
charging value.
Function "Overtemperature protection for the collector" can reactivate the collector
pump until the maximum storage tank temperature is reached.
If the storage tank reaches the maximum storage tank temperature set here,
charging is aborted. It will be released again when the storage tank temperature
has dropped 1 °C below the maximum.

An activated "Recooling" function remains active until the set recooling temperature
in the DHW storage tank is reached.
Surplus energy can be drawn off either by the heating circuits/consumer circuits or
the generator. This can be selected separately for each heating circuit / consumer
circuit (operating page "Heating circuit / consumer circuit X...")
When the collector is cold, the excess energy can be emitted to the environment
via the collector's surfaces.
