The unit does not start
1. Check the power supply
2. Check the fuses in the control box.
Only for units in the 400 V rotary current series.
3. Check the safety temperature limiter.
If the safety temperature limiter (STB) has been acti-
vated, the reason the unit overheated must be deter-
mined. The following are possible causes:
◊
The unit could not cool down because the
power supply was interrupted. Even short inter-
ruptions can activate the STB.
◊
The temperature of the air being blown out is
too high because the grilles have not been prop-
erly adjusted.
◊
The fan was overloaded and the thermal over-
current relay of the 400 V series was activated
or the thermal contacts in the fan motor of the
230 V series were activated.
◊
The V-belt of the fan drive is loose or defective.
◊
Air intakes and outlets are blocked.
4. Check the operating and/or main switch.
5. Check the room thermostat setting.
The room thermostat must be set higher than the
room temperature.
6. Set the operating switch to “Lüften” (fan) or “
II
”.
If the air supply fan starts now, look for the problem
in the burner.
Troubleshooting
The unit was subjected to repeating testing during pro-
duction to ensure that it functions properly.
However, if you still experience functional problems,
please refer to the list below.
The burner does not start
◊
Check whether the fuel filter is dirty.
◊
Check whether the shut-off valve of the fuel filter is
open.
◊
Check that there is enough fuel in the fuel container.
◊
Check whether paraffin has accumulated in the heat-
ing oil.
This can occur at temperatures below 5 °C.
◊
Check oil lines for damage.
Leaks can cause air intake.
◊
Use suitable means to ensure that the safety tem-
perature limiter (STB) and the temperature monitor
(TW) are functioning properly.
◊
Check the sensors and capillary pipes of the TW and
STB for damage and ensure that the sensor has
been properly positioned.
◊
Check whether the burner malfunction control lamp
on the oil firing device is illuminated.
If so, release the relay by pressing the malfunction
button. The malfunction light goes out and the burner
tries to start. Keep in mind that some burners have a
delayed start due to the oil preheating process for
some units.
G
If, after the start phase, the burner switches off due
to a malfunction, you may only re-release it after
waiting 5 min. Additional releases are strictly pro-
hibited as there is a risk of explosion.
The air supply fan does not start
◊
Set the operating switch to “Lüften” (fan) or “
II
”.
The air supply fan should now start.
◊
Check that the fan and the fan drive are running
smoothly.
◊
Check the V-belt on the fan drive.
◊
Check the electric cord on the fan motor for damage.
◊
Check whether the capacity of the fan was ex-
ceeded.
The thermal overcurrent relay (400 V series) or the
thermal contacts (230 V series) in the fan motor
have been activated.
◊
Check the operating capacitor of the fan.
Only for the 230 V series.
◊
Check that the temperature control thermostat (TR)
is working properly.
G
Should the unit still not function properly after per-
forming these checks, please contact an author-
ised service centre.
G
Please carry out an electrical safety test after hav-
ing finished service on the unit.
G
For safety purposes, repair work on the electrical
components and the burner may only be per-
formed by authorised personnel.

An operation/use other than indicated in these in-
structions is prohibited!
