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 voltage tester or lamp,
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.
Further details on burner
malfunctioning (LED code) can be
found in the enclosed burner operating
instructions.
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).
