6. Protective Functions

Seizing Protection

If the anti-seizing protection is activated, the controller will switch the heat pump and the mixer on/off for 5 seconds at 12:00 noon
to prevent seizing of the pump/valve after long periods of inactivity.

Frost Protection

If the outdoor temperature on sensor S1 measures less than 1 °C and the heating circuit is turned off, the heating circuit will auto-
matically be turned on, if frost protection is activated and the reference flow temperature is set at the minimum flow temperature;
setting under 'Min. Flow' on page 1. As soon as the outdoor temperature exceeds 1 ° C, the frost protection is switched off again.
Switching the frost protection function off or setting the minimum flow temperature too low can lead to severe damage
to the system.
