5.1 Use of the control panel
5.1.1 Browsing in the menus
Press any key to turn on the backlight for the control panel screen.
Important
If no key is pressed within 3 minutes, the backlight will go out.
The key is used to access the various menus:
Tab.3 Menus available

Press the key to access the Information menu.
Press the key for 2 seconds to access the Chimney Sweep menu.
Keep pressing the key to scroll through the information.
Note
Thirty minutes after the key is pressed for the last time, the dis
play goes back to the main display.
5.2 Start-up
If the boiler was powered off:
1. Check that the heating system and the boiler are adequately primed
with water. Recommended pressure: 0.15 MPa (1.5 bar).
2. Check that the storage tank is filled with fuel.
3. Open the oil inlet valve.
4. Switch on the boiler.
A venting cycle is run automatically.
The display shows the operating status of the boiler, the heating flow tem
perature and any error codes.
5.3 Shutdown
5.3.1 Switching off the heating

5.3.2 Stopping domestic hot water production
1. Turn the setting button all the way to the left until is dis
played.
Note
Frost protection continues to run on the domestic hot water tank.
The venting cycle is not tripped when domestic hot water produc
tion is shut down.
5.3.3 Shutting down the installation
It is recommended that the boiler is kept powered on to ensure frost pro
tection.
5.4 Frost Protection
Caution
The frost protection function does not work if the boiler is powered
off.
Caution
The integrated protection system only protects the boiler, not the
heating installation
Caution
Have the boiler and heating system drained by a qualified profes
sional if the home is left empty for a long period of time and there
is a chance of frost.
Important
To prevent the radiators and the installation from freezing in pla
ces where that risk exists (e.g. in a garage or an equipment room),
we recommend the connection of an outside temperature sensor
to the boiler.
If the temperature of the water in the boiler falls too much, the integrated
protection device switches itself on. This device functions as follows:
If the water temperature is lower than 7°C, the circulation pump starts
up.
If the water temperature is lower than 4°C, the boiler starts up.
If the water temperature is higher than 10°C, the boiler shuts down and
the circulation pump continues to run for a short time.
