5.4 Frost Protection
If the temperature of the heating water in the heat pump falls too much,
the integrated protection device switches itself on. This device functions as
follows:
If the water temperature is lower than 5°C, the circulating pump starts
up.
If the water temperature is lower than 3°C, the back-up starts up.
If the water temperature is higher than 10°C, the back-up shuts down
and the circulating pump continues to run for a short time.
The radiator valves in rooms where there is a risk of frost must be fully
open.
