Anomaly signalled Cause Appliance status / Solution
61
Air in circulator
pump anomaly
Air is detected inside the pump; the pump cannot work.
Vent the pump and the central heating
circuit. If normal conditions are
restored, the appliance 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 al-
tered in the air / gas section, thus requiring “complete cali-
bration”.
e appliance does not start (1)
72
Fast calibration
required
e P.C.B. detects that some parameters have been altered,
thus requiring “fast calibration”.
e appliance does not start (1)
73
High deviation
between ow probe
and safety ow probe
Faulty ow sensor or not correctly inserted.
If normal conditions are restored, the
appliance restarts without having to
be reset (1)
74
Safety ow probe
anomaly
e board detects an anomaly on the NTC safety ow
probe.
e appliance does not start (1)
77
Combustion control
anomaly
Out of range current is detected on the gas valve. e appliance does not start (1)
78
Combustion control
anomaly
High current on the gas valve is detected. e appliance does not start (1)
79
Combustion control
anomaly
Reduced current on the gas valve is detected. e appliance does not start (1)
80
Block - gas valve
driver issue
is occurs in the event of malfunctions of the P.C.B. that
controls the valve.
Press the Reset button (1)
84
Combustion anomaly
(Power reduction in
progress)
A low supply pressure is detected on the gas line. As a result
the appliance power is limited and the anomaly is reported.
If normal conditions are restored, the
appliance restarts without having to
be reset (1) (2)
87
Block - gas valve
control
A malfunction of one of the components that controls the
gas valve has been detected.
e appliance does not start (1)
88
Block - gas valve
control
A malfunction of one of the components that controls the
gas valve has been detected.
e appliance does not start (1)
89
Combustion signal
unstable
e ame is unstable due to: presence of ue gas recircula-
tion, wind, unstable gas pressure, unstable fan speed, or
due to system malfunction.
e appliance keeps working (1) (2)
90
Combustion signal
beyond limit
e combustion signal is beyond the adjustment range re-
quired for an extended period of time.
e appliance keeps working (1) (2)
(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Service Centre)
(2) e anomaly can only be veried in the list of errors in the “Information” menu
(3) Error displayed only on CAR
