Code
Anomaly signalled Cause Boiler status / Solution
10
Insucient system
pressure
Water pressure inside the central heating circuit that is sucient to guar-
antee the correct operation of the boiler is not detected.
Check on the boiler pressure gauge (1) that
the system pressure is between 1÷1.2 bar
and restore the correct pressure if necessary.
15 Conguration error
If the board detects an anomaly or incongruity on the electric wiring, the
boiler will not start.
If normal conditions are restored the boiler
restarts without having to be reset. (1)
20 Parasite ame
is occurs in the event of a leak on the detection circuit or anomaly in
the ame control unit.
Press the Reset button. (1)
24
Push button control
panel anomaly
e board detects an anomaly on the pushbutton panel.
If normal conditions are restored the
boiler restarts without having to be reset.
(1)
27
Insucient circula-
tion
is occurs if there is overheating in the boiler due to insucient water
circulating in the primary circuit; the causes can be:
- low system circulation; check that no shut-o devices are closed on the
central heating circuit and that the system is free of air (deaerated);
- blocked pump; free the pump.
Press the Reset button. (1)
31
Loss of remote
control communi-
cation.
This occurs if communication is lost between the boiler and the CAR
V2
.
Disconnect and reconnect the power to the
boiler. (1) (2)
37
Low power supply
voltage
This occurs when the power supply voltage is lower than the allowed
limits for the correct boiler operation.
If normal conditions are restored the boiler
restarts without having to be reset. (1) (2)
38 Loss of ame signal
This occurs when the boiler is ignited correctly and the burner flame
switches off unexpectedly; a new attempt at ignition is performed and
if normal conditions are restored, the boiler does not have to be reset.
If normal conditions are restored the boiler
restarts without having to be reset. (1) (2)
43
Block due to loss of
continuous flame
signal
This occurs if the ‘’Flame signal loss’’ error occurs 6 times consecu-
tively in 8.5 minutes (38)”.
Press the Reset button. (1) (2)
(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Technical Aer-Sales Service).
(2) Error codes over 31 are not shown on the CAR
V2
display.
