Error Code Description of the Error Malfunction Probable Cause Solution(s)
E 88
Fault of electronic gas
valve managing circuit
Boiler does not work, E88
error code flashing on the
screen
> Cabeling disconnections
> Gas valve failiure
1-) Call for authorised service at first
2-) Check gas valve cabeling between board and gas valve
3-) Measure gas valve coil ressistances according to manual if gas
valve coils out of tolerance, then replace gas valve
4-) Always perform Au-To calibration.
Attention: Only authorised service must perform Au-To calibration
E 89
Problem on combustion
feedback signal
Boiler does not work, E89
error code flashing on the
screen
> Aging or rust on the
electrode
> Recirculation on fluegas
path
> Blokage on flue or wrong
flue
> Electrode position
> Cabeling disconnections
> Combustion calibration
> Electronic board
> Gas valve failiure
1-) Call for authorised service at first
2-) Check wrong flue OR flue gas blockage
3-) Check recirculation ( flue gas leak ) from flue gas path to fresh air
side, check flue gas sealings specially
4-) Check any problems on the ionisation electrode, (like
condensation, rust etc.), and control poistioning of the electrode, if
electrode poistion wrong calibrate the electrode.
5-) Check for condensation on the cabling AND/OR on board
6-) Check earth connection between board and electrode
7-) Check electrode cabeling between board and electrode
8-) Check combustion CO or O values on HI and LO mode at
sweeper mode.
9-) Perform Auto Calibration.
10-) if not successfull replace gas valve, and perform Au-To calibration.
11-) If fault still persists Replace board, but use original service key
from the board dismantled to keep original parameters and calibration
points. If original service key not used aslo adjust P15 releated to the
default value of boiler power and perform Au-To calibration.
Attention: Only authorised service must perform Au-To calibration

E 92 Air compensation active
Boiler does not work, E91
error code flashing on the
screen
> Possible wind precence
> Aging or rust on the
electrode
> Recirculation on fluegas
path
> Blokage on flue or wrong
flue
> Electrode position
> Combustion calibration
> Min power adjustment
1-) Call for authorised service at first
2-) Check wrong flue OR flue gas blockage
3-) Check recirculation ( flue gas leak ) from flue gas path to fresh air
side, check flue gas sealings specially
4-) Check any problems on the ionisation electrode, (like
condensation, rust etc.), and control poistioning of the electrode, if
electrode poistion wrong calibrate the electrode.
5-) Check combustion CO or O values on HI and LO mode at
sweeper mode.
6-) Perform Auto Calibration.
7-) If boiler place is windy area then increase Minimum power to 5 kw
via TsP parameter P10= in between 5 and 7.
Attention: Only authorised service must perform Au-To calibration
