Replace dirty filters.
2. Check that all shut-off fittings in the oil supply are
open.
3. Check that there is enough fuel in the fuel container.
4. Check whether paraffin has accumulated in the
heating oil.
This can occur even at 5 °C.
5. Check oil tubes for damage.
6. Check the sensors and capillary pipes of the safety
devices for damage or dirt.
7. Check that the temperature monitor (TW) is working
properly.

Unit does not start:
1. Check power supply.
400 V / 3~N.
2. Set operating switch to “I”.
3. Ensure that the “operation” lamp on the control
panel is illuminated.
It must indicate that the unit is in “heating” mode.
4. Check that the bridge circuit plug or the thermostat
plug has been plugged in correctly.
5. Check the room thermostat setting.
The temperature set on the room thermostat must
be higher than the room temperature.
6. Check whether the safety temperature limiter (STB)
was activated.
You must remove the protective cover next to the
control panel.
7. Before resetting the STB, it is absolutely necessary
to determine the reason it was activated and take
appropriate measures.
The following are possible reasons:
− Unit could not cool down because the power sup-
ply was interrupted.
− Temperature of air being blown out is too high be-
cause hoses are not directing air properly.
− Air intakes and outlets are blocked.
8. Check whether the “burner malfunction” control
lamp on the control panel is illuminated.
If so, release the automatic burner relay by pressing
the reset button.
9. Set operating switch to “II”.
If the fan now starts running, look for the malfunc-
tion in the burner.
