11 - SAFETY DEVICES AND ALARMS
ALARM SIGNALLING
When a condition occurs other than the one expected for regular operation of the boiler, an alarm is triggered.
The reason for the alarm is given on the control panel. The sound signal is not enabled for alarms A01-A02 in order not to disturb the user
when there is an absence of pellets in the tank during the night.
