If the central heating system is not used for a long period, we
recommend switching the boiler 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.
CAUTION
Drain the boiler and central heating system if you are not
going to use your home or the building for a long time and
there is a chance of frost.
Set the temperature control low, for example at 10°C.
To prevent radiators and the system from freezing in rooms where
there is a risk of frost (e.g. a garage or storage room), a frost
thermostat or outside sensor can be connected to the boiler.
¼See also: "Connection options", page 34.
CAUTION
The antifreeze protection does not function if the
4
boiler is switched off.
The integrated protection system only protects the
4
boiler, not the installation.
Open the valves on all radiators connected to the
4
heating system
If the boiler has been placed in a room at risk of frost,
4
the condensate drain and condensate trap should
preferably be protected against freezing with a frost
protection cable.
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.
