4.3 Prolonged absence

4.3.1

Switching off the appliance

If the central heating system is not used for a long period, we
recommend switching the boiler off.
1. Switch the boiler off.
4.3.2

Antifreeze protection

The boiler must be installed in a frost-free environment.
We recommend setting the boiler thermostat to a value off 10°C if
using a classic installation.
If the temperature of the central heating water in the boiler falls too
much, the integrated protection device switches itself on:
- If the water temperature is lower than 7°C, the circulating pump is
activated.
- If the water temperature is lower than 3°C, the boiler is activated.
- When the water temperature is above 10 °C, the boiler is switched
off and the circulation pump runs for another 15 minutes.
