ALARM ALERTS
Whenever an operating condition other than that designed for the regular operation of the boiler occurs, there is an alarm condition.
The control panel gives information on the reason of the alarm in progress. A sound signal is not envisioned for alarms A01-A02 only so to
not disturb the user in the event of pellets running out in the hopper during the night.

before maintenance. Contact the service centre.
ALARM RESET
To reset the alarm one must press and hold key 1 (ESC) for a few seconds. The boiler performs a check to determine if the cause of the
alarm persists or not.
In the first case the alarm will still be displayed, in the second case it will go onto OFF.
