e LED on the circuit board is flashing when the plant is operating and the electronics are
working as intended. If the LED stops flashing and shows a steady light, the burner has stopped
due to some fault, and one of the following texts is displayed:
PC SHORT
(photocell short-circuited) = Photocell broken, must be replaced.
IGN.FAIL
(Ignition failed) = Burner has made repeated ignition attempts without
the photocell detecting any flame; the feed auger can
have tripped, or the ignition coil might be broken. For
more on these and other causes, please see chapter
“Trouble-shooting”.
FEEDTIME = Feed auger operating time necessary to provide the
required ignition fuel. Normal operating time is 45–90
sec.
PAUSTIME = Pausing time for the auger when running at intervals.
For running continuously, this time must be set to 0.
RUNTIME = Running time for the auger when running at inter
vals. For running continuously, this time must be set to 0.
IGN.TIME = Max. time for ignition coil; should be set to max. 8
minutes.
AFT.BLOW = Fan shut-down delay after the thermostat cutting
(Fan after-blowing) out. Normal after-blowing time is about 200 sec.
FAN DEL. = Set to 0: Fan starts when the thermostat cuts in
(Fan delay) (preventilation); set to 1: Fan starts after ignition fuel
feed time is up; set to 2: Fan starts when the photocell
detects light (burner ignites using natural draught);
set to 3: Fan start can be delayed by a time after the
end of ignition fuel feeding (suitable for moist or
coarse fuel).
