Cause Corrective action
E8 Burner in fault mode The ionization current lies
outside the permissible range Check the ionization electrode and
cable. Press ”
RESET”.
E9 Burner in fault mode The ionization current lies
outside the permissible range
during calibration Check the ionization electrode and
cable. Check venting system for
leaks. Press ”
RESET”.
EA Burner in fault mode The ionization current lies
outside the permissible range
during calibration Check the ionization electrode and
cable.
Press ”
RESET”.
Eb Burner blocked Boiler control initiated a
combustion
calibration but could not
complete the
process - Heat generated by boiler must be
removed (boiler is cycling on
temperature limits, before calibration
process is complete)
- Check the connecting cable and the
ionization electrode, check the flue
gas system (flue gas recirculation).
- Verify pump operation
- Switching points of flow switch
marginal (not enough flow)
- Check coding card
- Check gas valve
- Check coding address 82
- Also see address 12:__
Press ”
RESET”.
EE
Burner in fault mode At burner start, flame signal
is missing or too weak Check the ionization electrode and
cable.
Check gas supply, condensate drain,
ignition and ignition module
Press ”
RESET”.
EF Burner in fault mode Flame is lost immediately
after it has built (during the
safety time) Check gas supply, check flue gas/
exhaust pipe/air intake for flue gas
recirculation, check ionization
electrode (replace if necessary)
Press ”
RESET”.
EC Burner in fault mode The ionization current lies
outside the permissible range
during calibration Check the ionization electrode and
cable. Press ”
RESET”.
Ed Burner in fault mode Internal fault Replace the control unit.
F0 Burner blocked Internal fault Replace the control unit.
F1 Burner in fault mode Maximum flue gas
temperature exceeded
(230ºF / 110ºC). Check heating system fill
level. Bleed air from system.
Press ”
RESET” after vent system
has cooled down.
