3840 Collector frost protection
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. Operating line
3850 Collector overtemp prot
If there is risk of overtemperature at the collector, storage tank charging is continued to
reduce the amount of surplus heat. When the storage tank's safety temperature is
reached, charging will be stopped.
