Note that for the gas boiler the power during burning is increased
slowly and is reduced as soon as the supply temperature is reached.
Frost protection function
The boiler is equipped with an internal frost protection function that
automatically operates when necessary, even if the boiler is turned
off. If the heat exchanger temperature drops too low, the burner will
switch on until the temperature is sufficiently high again. When frost
protection is active, is displayed on the service display.
