It is recommended that the boiler is kept powered on to ensure frost pro
tection.
If the temperature of the water in the boiler falls too much, the integrated
protection device switches itself on. This device functions as follows:
Stopping domestic hot water production
1. Turn the setting button
played.
Note
Frost protection continues to run on the domestic hot water tank.
The venting cycle is not tripped when domestic hot water produc
tion is shut down.
Shutting down the installation
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 profes
sional 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 pla
ces where that risk exists (e.g. in a garage or an equipment room),
we recommend the connection of an outside temperature sensor
to the boiler.
If the water temperature is lower than 7°C, the circulation pump starts
up.
If the water temperature is lower than 4°C, the boiler starts up.
If the water temperature is higher than 10°C, the boiler shuts down and
the circulation pump continues to run for a short time.
