4.3 Switching off the boiler
4. Operating the appliance
Set the On/Off switch to 0.
DIEMATIC-m3 control panel
The panel must always be supplied with 230V voltage:
- to ensure the anti-grip of the heating pump,
- to ensure Titan Active System® operation when a titanium anode
is protecting the DHW tank.
Use the mode:
- summer to shut down the heating.
- antifreeze to shut down the boiler if you are to be absent.
4.3.1 Precautions to take if there is a danger of frost
Heating circuit:
Use a correctly dosed antifreeze to prevent the heating water
freezing. If this cannot be done, drain the system completely. In all
cases, consult the fitter.
Domestic hot water circuit:
Drain the domestic water tank and pipes.
4.3.2 Precautions to take in the event of prolonged shutdown (one year or more)
- Close the gas valve
- The boiler and the chimney must be swept carefully.
- Close the door of the boiler to prevent the internal circulation of air.

6.3 Incidents and solutions
The burner is not working:
- Check the boiler thermostat settings.
- Shutdown by the safety thermostat due to accidental overheating
Check that the safety thermostat has not triggered. To restart the
boiler, reset the safety thermostat. Remove the safety thermostat
hood and press the reset button with a screwdriver. Carry out the
start-up operations again. Call your fitter.
- Check the circuit breaker
- The safety control box is malfunctioning (Fault indicator light
illuminated)
Press the resetting button of the burner. Call your fitter.
The burner is operating but the radiators are cold:
- Bleed the radiators.
- Top up the primary circuit with water.
If it is often necessary to top up the installation with water, contact
your fitter.
- Check that the heating pump is operating correctly.
- Check the position of the 3 position switch.

8 Energy savings
Here are a few tips for saving energy:
- Install reflector panels behind the radiators.
- Do not cover the radiators. Do not hang curtains in front of the
radiators.
- Insulate pipes to prevent thermal losses and condensation.
- Do not obstruct aeration grates (even partially). They help to
reduce humidity in the home. The more humid a home, the more
heating it consumes.
- Turn heating off when airing a room (5 minutes a day is sufficient)
Avoid deregulating the thermostat. Switch the On/Off switch to Off.
- Do not shut down heating completely if you are absent. Lower the
thermostat by 3-4°C.
- Use the sun's heat as much as possible.
- Take showers rather than baths. Use a water-saving shower head.
