Cause: Remedial measures:
1. Air in fuel system during start-up.
Press the fault key of the automatic burner.
Repeat if necessary (max. 3 times).
2. The unit is not connected to the electricity supply. Check the power plug, mains socket and mains voltage.
3. No plug in the thermostat socket. Connect the thermostat/strapping plug to the thermostat socket.
4. The room thermostat is set too low. Set the room thermostat higher than room temperature.
5. The fault lamp in the automatic burner lights up. Reset the automatic burner by pressing the malfunction button.
6. Malfunction in the automatic burner. Replace the automatic burner.
7. The motor is overloaded.
(The fan runs irregularly or is blocked)
Allow the motor to cool.
Check the smooth running of the fuel pump.
Check the electrical and mechanical functioning of the motor.
8. The fuel pump is blocked. Check the fuel pump and replace if necessary.
9. The fuel tank is empty. Fill the fuel tank with clean EL heating oil or diesel.
