Frost protection for the collector
Line no. Operating line
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.
Overtemperature protection for the collector
Line no. Operating line
3850 Collector overtemp prot
If there is a risk of overtemperature at the collector, storage tank charging is continued
to reduce the amount of surplus heat. When the storage tank safety temperature is
reached, charging will be stopped.

Medium’s evaporation temperature
Line no. Operating line
3860 Evaporation heat carrier
If there is a risk of the heat carrying medium evaporating due to high collector
temperatures, the collector pump will be deactivated to prevent it from reaching
excessive temperatures. This is a protective pump function.
Speed control
Line no. Operating line
3870 Pump speed min
3871 Pump speed max
The solar pump motor speed is limited by a minimum and maximum permitted speed.
