When the heating water temperature in the boiler falls by too much,
the integrated protection system in the boiler 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 7°C, it is
reheated to its set point.
CAUTION
Do not switch off the mains supply to the appliance. If the
central heating system is not used for a long period, we
recommend activating the HOLIDAYS mode (to ensure
the anti-grip of the heating pump).
