F39 External probe fault
Probe damaged or wiring
shorted
Check the wiring or replace the sensor
Probe disconnected after
activating the sliding tempe-
rature
Reconnect the external probe or disable the
sliding temperature
F19 Card parameter fault
Wrong card parameter set-
ting
Check and if necessary modify parameter
b15 to 3
F50 - F53
Limit thermostat fault with
parameter b06 = 1 or 4
No/poor water circulation in
the system
Check the circulating pump and heating
system
Air in the system Vent the system
Incorrect parameter Check the correct parameter setting
A64
Maximum number of con-
secutive Resets exceeded
Maximum number of conse-
cutive Resets exceeded
Disconnect the power supply to the boiler
for
60 seconds and then reinstate the
boiler
F62 Calibration required
New card or boiler not yet
calibrated
Do complete manual calibration
A88
Specific combustion con-
trol errors or gas valve
Calibration activation with
burner lit.
Combustion problem, faulty
gas valve or PCB
Reset the fault and do
complete manual
calibration
.
If necessary, replace the gas valve or PCB.
F65 ÷ F98
Specific combustion con-
trol errors
Fume ducts obstructed.
Low gas pressure.
Condensate trap blocked.
Fumes recirculation or com-
bustion problem
Check that the fume ducts and the conden-
sate 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 calibra-
tion.
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 com-
bustion problem
Check that the fume ducts and the conden-
sate 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 calibra-
tion.
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 complete
manual calibration.
Fume ducts obstructed.
Low gas pressure.
Condensate trap blocked.
Fumes recirculation or com-
bustion 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 igni-
tion. Do a complete manual calibration and,
if necessary, replace the PCB.
F96
Specific flame combustion
error
Unstable flame or unstable
flame signal after ignition.
Check the gas supply, fume ducts and con-
densate 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 parame-
ter b11.
A80
Parasite flame signal after
valve closing
Electrode problem.
Gas valve problem.
PCB problem.
Check the correct position and condition of
the electrode.
Check the PCB.
Check the gas valve and replace it if neces-
sary.
