If the central heating system is not used for a long period, we
recommend switching the boiler off.
4 Switch the On/Off switch to Off.
4 Switch off the boiler electrical power supply.
4 Shut off the gas supply.
4 Ensure that the boiler and system are protected against frost
damage.
When the heating water temperature in the boiler is too low, the
integrated boiler protection system starts up. This protection functions
as follows:
4 If the water temperature is lower than 7°C, the heating pump starts
up.
4 If the water temperature is lower than 4°C, the boiler starts up.
4 If the water temperature is higher than 10°C, the boiler shuts down
and the circulation pump continues to run for a short time.
4 If the water temperature in the storage tank is less than 4°C, it is
reheated to its set point.
