Installation
Adjusting control electronics
Potentiometers P1-P5 are adjustment potentiometers for
trimming the functions of the burner. The potentiometers
are designated with the relevant abbreviations (P1-P5).
The circuit board has 3 LEDs (LD1,LD2,LD3).
Functions P1-P5
Pot Function Seconds Comments
P1 Feed time igni-
tion dose (start
fuel) 30 – 165 Pellets must just
cover the upper
ignition hole on the
ignition plate.
P2 Firing supply 1,5 – 8,2 Pellets fed every 15
seconds.
P3 Extinguishing
time 30 – 300 The time the fan
runs after the photo-
cell has lost light in
the burner.
P4 Overrun time (at
25% supply) 45 – 450 Time between igni-
tion and normal
operation.
P5 The sensitivity of
the photocell 0 – 9 9= max fire/light
intensity, 0= min fire/
light intensity.
Reading off potentiometers
To see how a potentiometer is set, the relevant potentiom-
eter flashes first on LD3 (green) and then the value which
is set on LD2 (yellow) flashes. This occurs continuously,
1,2,3,4,5,1,2,3…… regardless of whether the burner is in
operation or not.
Example: If the photocell loses light for more than 3 sec-
onds the fan runs for a further 6 seconds, the burner then
carries out normal extinguishing according to the set value
on P4.
Do not adjust the burner during operation
