Alarm relay with indicator.17. Relay with indicator for feed auger.18. OPERATION: (green)On constantly: there is power supply to theburner.Flashing: start delay.19. POWER: (green)On constantly: high power.One long + one short flash: low power.One long + two short flashes: cooling.20. FLAME: (orange)On constantly: photoresistor senses flame.Flashing: start phase.One long + four short flashessynchronously with ALARM: low fan RPM in operatingphase.21. ALARM: (red)On constantly: high temperature,downpipe.One long + one short flash: monitoring of feed augermotor.One long + two short flashes: three failed starts.One long + three short flashes: high ambient temperature.One long + four short flashes: fan not working.One long + four short flashessynchronously with FLAME: low fan RPM in operatingphase.Flashing: low element current.22. TEMP: temperature setting when burner controls boilertemperature. Requires temperature sensor(accessory).23. START DOSE: pellet dose setting at start.24. Switches for setting operating parameters:Power mode, switches SW1/1 and SW1/2Two power modesswitch from 22 to 35 kW when theburner has burned at 22 kW for 20 min.OFF (SW1/1)OFF(SW1/2)Low power, 22 kW ON (SW1/1)OFF(SW1/2)High power, 35 kW OFF(SW1/1)ON (SW1/2)Feed auger supply feed time, switch SW1/3OFF =LongON =ShortPellet diameter, switch SW2/1OFF = Ø6 mm ON = Ø8 mmSwitch SW2/2 - no functionSwitch SW2/3 - Always ‘ON’!Always ‘ON’!25. Fuel: fuel volume setting for high power operation.26. Start delay: 0 - 135 minutes. See ‘Start delay’ underPellet firing.27. Air, LOW Power: air flow rate setting for low power.28. Serial interface for reading off the burner’s settings,operating times and operating parameters. Requiresserial cable or read unit (accessories).29. Indicator. Lights up when the ignition element is connected.30. Single-chip computer, which controls and monitors theburner.With any change of circuit board, it is importantfor the new circuit board to be installed correctly.The index marking must be upwards. See figure.The burner must be disconnected from the powersupply.index30
