No ignition.
If the flame does not start during the ignition phase, or the flue
gas temperature does not reach an adequate value in the time
set for ignition, the boiler with switch off and "ALAR NO ACC"
will appear on the display.
Press the "On/Off " button to reset the alarm.
Wait for the cooling cycle to complete, clean the brazier and

Switch-off during the work phase.
This happens in the event of unexpected boiler switch-off during
normal operation (for example, pellet finished in the tank or due
to a pellet loading gearmotor fault).
The boiler continues to operate until any pellet in the brazier
have finished burning, then "ALAR NO FIAM" will appear on
the display and the boiler switches off.
Press the "On/Off " button to reset the alarm.
Wait for the cooling cycle to complete, clean the brazier and
proceed with ignition once again.
These alarms are to signal that before ignition, you must make

Blackout.
If there is a blackout for a few seconds, when the mains voltage
is restored, the boiler immediately returns to the operating state

If there is a blackout long enough for the flue gas temperature to
drop below the reference value threshold (55 °C), when restored,
the boiler shuts down and "ALAR NO FIRE" is displayed.

System pressure is electronically controlled and must be between
0.5 and 2.3 bar. If this is not so, the boiler will trigger an alarm
and "ALAR PRESS" will be displayed.
