G. ALARMS DISPLAYING
The alarms are displayed on the command panel; on the first line the message ALAR appears,
while on the second line the typology of the anomaly is displayed. The occurring of an alarm
provokes the immediate stop of the boiler, and only after solving the problem it is possible to restart
the boiler, following the instructions already reported on this handbook.
Here below we report a list of the alarms with their possible causes and the possible resolution of
the problem.
Fumes temperature probe
ALARM SOND FUMI
Unsuccessful lighting
ALARM NO FIRE
Switching-off while working
ALARM NO FIRE
Power failure alarm
ALARM NO FIRE
General safety thermostat
ALARM SIC FAIL
Room thermocouple
ALARM ON T o 81°C
Pressure transducer of the water circuit
ALARM PRES
g.1 Fumes temperature probe alarm
It occurs in case of breakdown or disconnection of the fumes temperature probe. The boiler will
switch off automatically; then check for the wires to be properly connected, or substitute the fumes
probe if necessary.
g.2 Unsuccessful lighting alarm
It occurs when the lighting phase is unsuccessful; or in case the boiler does not reach the lighting
temperature, at a gradient of 3°C per minute. The boiler will automatically activate the switching-off
procedure.
g.3 Switching-off while working alarm
It occurs if the flame runs out, or if the fumes temperature is lower than the minimum working
threshold. The boiler immediately activates the switching-off procedure.
g.4 Power failure alarm
When the boiler is on, the lack of the power supply provokes the stop of its electric devices. If the
re-establishment of the power supply takes place within a few seconds, the boiler restarts its
normal activities.
