Please, take your time to read this description carefully.
!
CAUTION:
The control board of burner is under the high voltage!
After connecting the burner to the main with the connection cable turn the thermostat
anticlockwise and turn on the main switch on the boiler.
Now watch the two diodes blinking on the top of board (limit switch of burner has to be pushed).
One diode shows the potentiometer actually read and the second diode shows the value set on
this potentiometer. Now have a look at the internal side of the burner cover (see also the chapter
„Settings of control electronics"). The tabel hereby shows, how many blinks are adequate for
certain value. Most important value for the installer is the value of potentiometer P2, indicating
pellet feeding intensity during the heating process. It controls the quantity of fuel feeded to the
burner: the more of blinks, the more of fuel.
Lighting diodes and their function
Green diode LD3 signalize with blinking the potentiometer, which value is then shown.
This is followed by yellow diode LD2 which shows the value set on the appropriate
potentiometer by the number of blinks (see the Schedule of settings). Red diode LD1 lights
when the photocell has detected the flame/the light.
This blinking continues constantly, independently on if the burner is in operational or in stand-
by mode.
It is possible to find out the interval on which the actually readed potentiometer is set on, please
see the schedule on the internal part of burner cover.
