When there is risk of frost at the collector, the collector pump will be activated to
prevent the heat-carrying medium from freezing.
If the collector temperature falls below the frost protection temperature, the
collector pump will be activated: TKol < TKolFrost
When the collector temperature returns to a level of 1 °K above the frost protection
temperature, the collector pump will be deactivated again: TKol > TKolFrost + 1
Line no.

reduce the amount of surplus heat. When the storage tank's safety temperature is
reached, charging will be stopped.
