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 ame signal
is occurs when the boiler is ignited correctly and
the burner ame switches o unexpectedly; a new
attempt at ignition is performed and if normal condi-
tions are restored, the boiler does not have to be reset.
(1).
43
Block due to loss of
ame signal
is occurs if the ''Flame signal loss (38)'' error occurs
many times in a row within a preset period.
Press the Reset button (1).
44
Block for exceeding
the maximum ope-
nings close to the gas
valve
is occurs if the gas valve remains open for longer
than required for normal operation, without
the boiler switching on.
Press the Reset button (1).
59
Supply voltage fre-
quency anomaly
e board detects a main supply voltage frequency
anomaly.
e boiler does not start (1).
80
Failure signalled of
the gas valve modula-
tor pilot circuit
Possible failure to the gas valve modulator or electro-
nic board, cut-o wiring. e boiler operates to the
minimum DHW output.
Check the wiring connection and modulator coil
continuity (1).
98
Block - maximum no.
of soware errors
e maximum number of soware errors possible has
been reached.
Press the Reset button (1).
