Frost protection
Caution
The frost protection function does not work if the boiler is powered off.
Caution
The integrated protection system only protects the boiler, not the heating system.
Caution
Have the boiler and heating system drained by a qualified professional if the home is left empty for a long period of
time and there is a chance of frost.
Important
To prevent the radiators and the installation from freezing in places where that risk exists (e.g. in a garage or an

functions as follows:
