f) Frost protection function
When the frost protection function is active, the room ther-
mostat will prevent the room temperature to drop below 5
°C. The frost protection function thus prevents freezing of liq-
uid-based heatings and pipes. The frost protection temper-
ature is fixed at 5 °C in the factory and cannot be changed.
When the thermostat is in the frost protection function, the
symbol will be displayed.
