The display on the control panel provides information about the operating
status of the boiler and any errors. A maintenance message may also ap­
pear on the display.
The control panel manual provides information about the use of the panel,
changing and reading out parameters, the meaning of error codes and
how to clear the error memory.
See
Manual for the control panel.
If the central heating is not due to be used for a long period of time, it is
recommended that the boiler be disconnected from the power supply.
1. Switch off the boiler's electrical connection.
2. Shut off the gas supply.
3. Keep the area frost-free.
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.
The frost protection does not work if the boiler is out of opera­
tion.
The built-in boiler protection is only activated for the boiler and
not for the system and radiators.
Open the valves of all the radiators connected to the system.
Set the temperature control low, for example to 10°C.
If there is no heat demand, the boiler will only switch on to protect itself
against frost.
If the temperature of the central heating water in the boiler drops too low,
the built-in boiler protection system is activated. This system works as fol­
lows:
At a water temperature lower than 7°C, the heating pump starts.
If the water temperature is lower than 4°C, the boiler switches on.
If the water temperature is higher than 10℃ the boiler switches off and
the circulation pump continues to run for a short time.
To prevent the system and radiators freezing in frost-sensitive areas (e.g.
a garage), a frost thermostat or outside sensor can be connected to the
boiler.
