Installation shutdown
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).
4.5
Antifreeze protection
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.
