.

Fb

Burner in a fault state

3 x flame blow-off during
operation

Check oil supply, check nozzle.
Press reset button

R

.

Fd

Burner in a fault state and ad-
ditional fault b7 is displayed

Solenoid coil faulty
Control unit faulty

Check solenoid coil by temporarily
replacing it.
Check coding address 38: if the
value is at 38:33, the control unit is
faulty.
Before replacing the control unit,
check while the control unit is
switched on to see if the green
LED on the ignition unit is flashing.
If the LED is not flashing, also re-
place the ignition unit.

Fd

Burner blocked

Burner blocked or in a fault
state

Boiler coding card or main
PCB faulty, or incorrect
boiler coding card

Press reset button

R

. If the fault

persists, check the boiler coding
card and replace boiler coding card
or control unit if necessary.

FF

Burner blocked

Internal fault

Restart the appliance. Replace the
control unit if the appliance will not
restart.
