11-SAFETY DEVICES AND ALARMS
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.
Panel alert Type of problem Solution
A01
The fire does not ignite. Check whether the brazier is clean / level of pellets in
the hopper.
A02
The fire goes off abnormally. Check the level of pellets in the hopper.
A03
Thermostat alarms
The temperature of the pellets hopper or the
water temperature exceed the envisioned safety
threshold. Wait for the cooling stage to end, cancel the alarm
and restart the boiler setting the fuel loading at
minimum (SETTINGS menu - Pellets recipe). If the
alarm persists, contact the service centre.
Check if the room fan works properly (if present).

pellets loading (SETTINGS menu - Pellets recipe).

Service
Routine maintenance alert (it does not block
the system). When this flashing message appears upon start-up, it
means that the preset operating hours have elapsed
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.
If the alarm persists, contact the service centre.
