cod. 3541V300 - Rev. 00 - 02/2021
F65 ÷ F98
Specific combustion con-
trol errors
Fume ducts obstructed.
Low gas pressure.
Condensate trap blocked.
Fumes recirculation or
combustion problem
Check that the fume ducts and the con-
densate trap are not blocked. Check
the correct gas supply pressure.
Do a manual calibration to adjust the
CO
2
. If necessary, do a complete
manual calibration.
If the problem persists, replace the
PCB.
A65 ÷ A97
Specific combustion con-
trol errors
Fume ducts obstructed.
Low gas pressure (A78 -
A84).
Condensate trap blocked.
Fumes recirculation or
combustion problem
Check that the fume ducts and the con-
densate trap are not blocked. Check
the correct gas supply pressure.
Do a manual calibration to adjust the
CO
2
. If necessary, do a complete
manual calibration.
If the problem persists, replace the
PCB.
A98
Too many SW errors or
error occurred during
board replacement
Board replacement
Reset the fault and proceed with com-
plete manual calibration.
Fume ducts obstructed.
Low gas pressure.
Condensate trap blocked.
Fumes recirculation or
combustion problem.
Initially solve the problem, reset the
fault and check correct ignition.
Do a complete manual calibration and,
if necessary, replace the PCB.
A99
Generic error
PCB hardware or software
error
Reset the fault and check for correct
ignition. Do a complete manual calibra-
tion and, if necessary, replace the PCB.
F96
Specific flame combus-
tion error Unstable flame or unstable
flame signal after ignition.
Check the gas supply, fume ducts and
condensate drain. Check the correct
position and state of the electrode After
about 3 minutes the error is reset.
A44
Multiple requests error
Repeated short-term
requests
Check if there are pressure peaks in
the DHW circuit. If necessary, modify
parameter b11.
A80
Parasite flame signal after
valve closing
Electrode problem.
Gas valve problem.
PCB problem.
Check the correct position and condi-
tion of the electrode.
Check the PCB.
Check the gas valve and replace it if
necessary.
