Anomaly signalled Cause Boiler status / Solution
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).
38
Loss of fl 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
fl ame signal
This occurs if the ''Flame signal loss'' error occurs many times in a
row within a preset period (38).
Press the Reset button, before restarting,
the boiler will run a post-ventilation cycle
(1).
44
Block for exceeding the
maximum accumulat-
ed time, close gas valve
opening
This occurs if the gas valve remains open for longer than required
for normal operation, without
the boiler switching on.
Press the Reset button (1).
45 ΔT high
The boiler detects a sudden, unexpected increase in the Δ T between
the flow probe and the system return probe.
The power of the burner is limited to pre-
vent damage to the condensation module
and once the right Δ T is restored, the boiler
resumes regular operation. Make sure there
is water circulating in the boiler, that the
pump is configured according to system
requirements and that the return probe
works properly (1) (2).
46
Low temperature safety
thermostat (optional)
During normal operation, if an anomaly causes excessive overheat-
ing of the flow temperature in low temperature conditions, the boiler
blocks.
In this case, after suitable cooling, it is pos-
sible to reset the thermostat (see relative
instructions sheet) (1).
47
Burner power limita-
tion
Should flue high temperature be detected, the boiler reduces power
supplied so as not to damage it.
(1).
51
CAR Wireless com-
munication failure
If there is no communication between the boiler and Wireless version
CAR, an anomaly is signalled. From this moment, it is only possible
to control the system by means of the control panel of the boiler itself.
Check operation of the Wireless CAR,
check the battery charge (refer to the relative
instructions booklet).
59
Main supply voltage
frequency block
The board detects a main supply voltage frequency anomaly. The boiler does not start (1).
60
Anomaly pump
blocked
The pump is stopped due to one of the following causes:
Impeller blocked, electrical fault.
Try to unblock the pump as described in
the relative section. If normal conditions are
restored the boiler restarts without having
to be reset (1).
61 Air in circulator pump Air is detected inside the pump; the pump cannot work.
Vent the pump and the central heating cir-
cuit. If normal conditions are restored the
boiler restarts without having to be reset (1).
62
Complete calibration
required
Missing calibration is detected by the P.C.B. It may occur in the
event the P.C.B. is replaced or if the parameters are altered in the air
/ gas section, thus requiring “complete calibration”.
The boiler does not start (1).
72
Fast calibration re-
quired
The P.C.B. detects that some parameters have been altered, thus
requiring “fast calibration”.
The boiler does not start (1).
73
High fl ow probe and
safety fl ow probe
deviation detected.
The board detects an anomaly in the temperature readings of the
NTC flow probes; the causes may be: faulty probe, incorrect posi-
tion, poor system circulation, or clogging of the water side primary
heat exchanger.
If normal conditions are restored the boiler
restarts without having to be reset (1).
74
Safety fl ow probe
anomaly
The board detects an anomaly on the NTC safety flow probe. The boiler does not start (1).
77
Combustion control
anomaly
Out of range current is detected on the gas valve. The boiler does not start (1).
78
Combustion control
anomaly
High current on the gas valve is detected. The boiler does not start (1)
79
Combustion control
anomaly
Reduced current on the gas valve is detected. The boiler does not start (1).
80
P.C.B. malfunction
block
This occurs in the event of malfunctions of the P.C.B. that controls
the valve.
Press the Reset button (1).
(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Technical After-Sales Service).
(2) Th e anomaly can only be verified in the list of errors in the “Information” menu
