4. Operating the appliance 4.2.3 K3 control panel Heating temperature setting: Set the boiler thermostat to the desired setting. Make all other settings on the master boiler fitted with a DIEMATICm3 control panel Press the key. 4.3 Switching off the boiler - Set the On/Off switch to 0. - Close the gas valve 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. 4.4 Commissioning the boiler Initial commissioning must be done by a qualified professional. 1. Check the water pressure in the installation. Top up with more water if necessary. 2. Open the gas valve. 3. Make the settings on the control panel: B3 control panel: - Turn the switch TEST-STB/ / to. - Turn the pump shutdown switch to - Set the boiler thermostat to the desired setting. - When preparing domestic hot water: Set the DHW thermostat to the desired setting. Setting 6 (approx 60) recommended. DIEMATIC-m3 control panel: - Turn the AUTO / / TEST STB switch to AUTO. - Turn the pump shutdown switch to - Set the boiler thermostat to maximum (between 7½ and 9). K3 control panel (Secondary boiler in cascade with a DIEMATIC-m3 boiler): - Set switch AUTO / / TEST STB to the AUTO position. 4. Turn the burner switch to 2 (2 stage version) 5. Check that the safety thermostat has not triggered. Remove the safety thermostat hood and press the reset button with a screwdriver. 6. Set the On/Off switch to 1. Only for DIEMATIC-m3 control panel: When the boiler is switched on, the tank exchanger is purged for one minute if a tank is connected and its temperature is lower than 25 C. If disgassing has already taken place, press the MODE key to suspend disgassing. Only for DIEMATIC-m3 control panel: On commissioning, it is necessary to select the desired language with the + and - keys and confirm with the MODE key. 10 DTG 330 S 15/03/2016-300011852-02

If the boiler sensor fails, the burner is controlled by the boiler thermostat and the heating and DHW circuits operate normally. The boiler setting is equal to BOILER MAX. but can be limited by the boiler thermostat to a lower value. - The valve setting is no longer ensured but monitoring the maximum temperature of the circuit after the valve is ensured. - Valves may be manually operated. - Reheating the domestic hot water remains ensured. To ensure domestic hot water production, set the switch AUTO/ /TEST- STB to. The circuit concerned goes from automatic to manual mode: The pump operates. The circuit concerned operates without any influence from the room sensor. This failure has no impact on the operating modes. Pool reheating is independent of its temperature. Reheating domestic hot water using the solar panel is no longer ensured. The hot water storage tank reheating operation is no longer assured. 12 DTG 330 S 15/03/2016-300011852-02

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. 14 DTG 330 S 15/03/2016-300011852-02
