9. Troubleshooting

Problem
Burner is not running

Possible cause

No power supply
Room thermostat (if being
used) has been set too low
Room thermostat is defective
Automatic oil lighting device
indicates disturbance (Lamp
indicating disturbances lights
up).
The safety temperature limiter
has interrupted the power
supply, blow-out temperature is
too high, air input and air output
have been narrowed down or
device could not cool off
afterwards: device was
switched off by pulling out the
plug, instead of by switching off.

Solution
Check with a two-pole voltage
tester or multimeter, turn on the
main switch, change the fuse,
check the supply line for loose
contacts.
If device is being operated without
room thermostat: check whether
the cap of the room thermostat
connection is on, since the heater
will not start up without the cap, if
necessary, place the cap on (the
cap contains a power supply
bridge).
Set room thermostat above room
temperature
Examine room thermostat (can
only be carried out by an expert).
Change it or bridge it over at the
fastening clamp on the device in
emergency cases and switch it on
manually.
Unscrew the switch cabinet
covering. After waiting for approx.
1 minute, activate the lit up button
for removing disturbances on the
control unit of the burner. The
indication of a disturbance on the
control unit and signal should go
off. The burner then attempts to
start up again.
When starting up initially, it is
possible that the button for
removing disturbances has to be
pressed so often, until the burner
has sucked in oil that is free of air.
Check that the oil in the reverse
flow pipe is free of bubbles.
Heating up will only be possible
after this.
Turn the black protective cap to
the left and remove it. Press the
button for removing disturbances
on the STB. This can be found
above the entry point for the
device cable. Get rid of the cause
for overheating (resistance to
suctioning-in or blowing out).
