88.4 Frost Protection

The electronic management system of the boiler includes protection

against frost. If the water temperature falls below 5°C, the burner starts up

in order to provide a water temperature of 30°C.
This function only works if the boiler is turned on, the gas supply open and

the hydraulic pressure correct.
