4 Operation

4.10 Frost protection

The frost protection feature only protects the boiler. Any
other parts of the system liable to frost damage should
be protected accordingly.
Caution
The frost protection and monitoring systems
are only active when the main ON/OFF control
of the appliance is in the "I" position and it is
not disconnected from the main power supply.
Frost protection function
The boiler has a frost protection function.
If the heating flow temperature falls below 5 °C with the
main ON/OFF control turned on, the appliance starts up
and heats the boiler to 30 °C.
Caution
Parts of the system may freeze.
The frost protection function cannot guarantee
that water flows through the entire heating sys-
tem.

The reliability of the appliance can be impaired,
resulting in damage to property or personal
injury if maintenance work is not carried out.
Regular servicing ensures maximum efficiency and eco-
nomical operation of your gas wall heater.
