Bei Frostgefahr am Kollektor wird die Kollektorpumpe in Betrieb genommen, um das
Einfrieren des Wärmeträgers zu verhindern.
Sinkt die Kollektortemperatur unter die Frostschutztemperatur schaltet die
Kollektorpumpe ein: TKol < TKolFrost.
Steigt die Kollektortemperatur um 1°K über die Frostschutztemperatur wird die
Kollektorpumpe wieder ausgeschaltet: TKol > TKolFrost + 1.
