Once the preceding actions have been carried out, the appliance may be started up.
1. Press the button , to start the appliance.
The heat exchanger is heated up and the service display will show 3, 4 and 6
(depending on the status of the DHW disabling switch and/or Open Therm regulation).
2. Adjust the pump setting depending on the maximum power set and the resistance in the
CH installation. For the water head of the pump and the pressure loss of the appliance see
§ 10.5.
3. Set the room thermostat higher than the room temperature. The appliance will now switch
to CH operation: 5 will show on the display.
4. Heat the installation and the appliance to approximately 80°C.
5. Check the temperature difference between the supply and return for the appliance and the
radiators. This must be approximately 20°C. For this purpose set the maximum power on
the service panel. See setting maximum power. If necessary adjust the pump setting
and/or the radiator valves. For the minimum flow see § 10.5.
6. Switch the appliance off.
7. Bleed the appliance and the installation after cooling (if necessary top up).
8. Check correct operation of the heating and hot water supply.
9. Instruct the user on filling, bleeding and the operation of the clock, heating and hot water
supply. For setting the clock see § 9.3.
Notes
•
The appliance is equipped with an electronic boiler controller, which ignites the
burner and continuously monitors the flame during each request for heat from the
heating or from the hot water supply.
•
The circulation pump starts running in response to every request for heat. The pump
continues running for 1 minute after heating. This post purge period can be changed
if desired (See § 10.3).
•
The pump runs automatically for 10 seconds every 24 hours in order to prevent
seizing. This will occur at the the time of the last request for heat. To change this time
the room thermostat should be turned up briefly at the desired time.
•
The pump does not run during DHW operation.
