START-UP IN OFF MODE
Cold start of the burner (with electric ignition)
Cold start of the burner takes place after the burner has been switched off at the cont-
rol panel, a fault has occurred in the operation of the burner, or the mains voltage re-
turns after a mains outage. The temperature of the boiler must be at least 8°C below
the set value. Otherwise, the automatic control unit supposes that the burner is in the
hot start mode and does not use the ignition resistor at all.
If the external feeding system is empty of pellets, it must be refilled before swit-
•
ching on the burner. Switch on the control unit of the burner at the main switch
so that the red light turns on. Press the arrow button to the right. The operation
display of the burner must be OFF. Browse menu 1 by means of the arrow button
forward, until the message “AUGER EXTERNAL MANUAL OFF” is displayed.
Switch on the external auger by pressing the Plus button. When the auger is ro-
tating, the remaining running time is indicated on the display. The external auger
can be stopped before the set time elapses by pressing the Minus button before
the drop tube begins to be filled with pellets.
To switch on the burner, go forward to menu 1 by means of the arrow button, until
•
OFF (+ON) appears on the display. Select ON by means of the Plus button. Then
the burner motors starts, the burner gets fuel to be fed to the combustion head via the
feed auger, and after 3 minutes also the fan and ignition resistor will be switched
on.
The optical sensor of the burner detects the moment when fuel has been ignited
•
and switches off the ignition resistor. At the same time, the operation light turns
green and the speed of the fan decreases. Feeding of fuel stops completely within
three minutes in order to give time for the fuel to ignite in the combustion head.
After this pellets are fed at low power for further five minutes. After a full stop
lasting ten minutes (7 starts), the operation program switches on and controls the
burner functions. Only until at this point the burner switches to the normal hea-
ting mode. In case the ignition fails, the red light will come on again and an alarm
message appears on the display.
The maximum amount of cold start cycles is seven. The proceeding of these cycles can
be followed on the display by selecting the menu option “Operating mode”. Don’t make
any adjustments on the burner or similar measures during the ignition cycle.
Note! When the burner is switched on at the first time or, for some reason, it does not contain any pellets, a
restart is sometimes required approx. after a 3 minutes’ running time
.
START-UP IN OPERATING MODE
Hot start and switching off
A green light indicates that the burner is in operating mode. During operation, the
temperature sensor of the boiler controls the start and stop functions of the burner.
When the temperature of the boiler has dropped 5°C below the selected set value, the
burner switches to medium power. If the temperature drops by further two degrees,
the burner starts to operate at maximum power. The burner operates at maximum
power, until the temperature has dropped four degrees below the set value, after which
the burner starts to operate at medium power again. The red light indicates that the
device has been switched off.
(see “Troubleshooting” ).
Switching off
To switch off the burner, select the menu “ON (OFF)”. Select OFF by means of the
Minus button. When the burner is in OFF mode, a red light is illuminated on the
control panel indicating that the power has been switched on.
