12.4 Alarms
Should any malfunctioning be detected, the control board reports the problem in question: the alarm LED switches on (alarm LED on) and the
buzzer goes off.
The possible alarm messages are listed below:

In case of alarm, the stove is always immediately switched off
EXCEPT FOR THE POWER OUTAGE ALARM , the alarm status is reached at the end of the period of time set by PR1 1 parameter and can be
cleared by holding P4 button down. Whenever an alarm is cleared, the stove starts a switching-off phase for safety reasons. The alarm LED
(alarm LED on) will remain on and the buzzer, if enabled, will sound intermittently during the entire alarm phase. Should the alarm not be
cleared, the stove will in any case be switched off and the alarm message will remain on the display.
12.4.1 Power outage alarm
Power outage may occur with stove in working mode. When power resumes, if the power outage period has been lower than the value
set by PR48 parameter, the stove will restart in the
WORKING mode. Otherwise the relevant alarm will be triggered. The message “Al
1 alar al 1 Blac-out” scrolls on the display and the stove switches off.
12.4.2 Fume temperature sensor alarm
The alarm is triggered in case of faulty fume sensor. The stove goes into the alarm status and the alarm LED switches on (alarm LED
on). The message “Al 2 alar al 2 Sonda fumi” will scroll on the display and the stove will switch off.
12.4.3 Fume overheating alarm
The alarm is triggered whenever the fume sensor detects a temperature higher than a fixed set value, which may not be modified by
means of a parameter. The message “Al 3 alar al 3 Hot fumi” appears on the display and the stove switches off.
12.4.4 Faulty fume encoder alarm
The alarm is triggered in case of exhaust blower failure. The stove goes into the alarm status and the message “Al 4 alar al 4 Aspirat–
guasto” will scroll on the display.
12.4.5 Ignition failure alarm
The alarm is triggered in case of ignition phase failure. This occurs when fume temperature does not exceed the value set by PR1 3 parameter
at the end of the period of time set by PR0 1 parameter. The message “Al 5 alar al 5 Mancata accens" scrolls on the display and the
stove goes into the alarm status.
12.4.6 No pellet alarm
The alarm is triggered when fume temperature falls below the value set by PR13 parameter with stove in working mode. The message
“Al 6 alar al 6 mancano pellet" scrolls on the display and the stove goes into the alarm status.
12.4.7 Thermal safety overheating alarm
The alarm is triggered whenever the general safety thermostat detects a temperature exceeding the trigger threshold. The thermostat
switches off the Auger tube, being connected in series to its power supply, the control board reports the alarm status (alarm LED on)
by showing the message “Al 7 alar al 7 Sicurec– termica” on the display and the stove switches off.
12.4.8 No negative pressure alarm
The alarm is triggered whenever the external pressure switch detects a pressure/negative pressure value below the trigger threshold.
The pressure switch switches off the Auger tube, being connected in series to each other, and the control board reports the alarm status
(alarm LED on) by showing the message “Al 8 alar al 8 Manca depress-” on the display. The stove switches off.
