PANEL ALERT
TYPE OF PROBLEM
SOLUTION
A19
Water probe faulty.
Water probe disconnected / interrupted / defective /
not recognised.
A20
Puffer probe alarm.
Puffer probe disconnected / interrupted / defective /
not recognised.
A21
Triac alarm
The triac of the electronic card has stalled. Replace the
card.
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.
12.15 ALARM RESET
NEVER open the stove door while it is starting up initially or switching off, as the pellets are
still burning at this point and there may be volatile substances.
ATTENTION!
If smoke flows into the room from the appliance or the flue during operation or initial igni-
tion, switch off the device, air out the room, and immediately contact the installation/custo-
mer service technician.
To reset the alarm, you must hold down key 1 (ESC) for a few seconds. The stove performs a check to determine whether what
caused the alarm is still present.
If this is the case, the alarm will be shown again, otherwise the stove will switch OFF.
If the alarm persists, contact a service centre.
12.16 NORMAL SHUTDOWN (ON THE PANEL: OFF WITH FLASHING FLAME)
If the shutdown key is pressed or if there is an alarm signal, the boiler goes into the thermal shutdown phase which entails the
automatic execution of the following stages:
• It stops pellets loading
• The room fan (if provided) maintains the set speed until the smoke T reaches 100°C, then it automatically sets itself at the
minimum speed until it reaches the shutdown temperature
• The smoke fan sets itself at maximum speed and maintains it for a fixed time of 10 minutes, at the end of which if the smoke
T has fallen below the shutdown threshold it switches off permanently, otherwise it sets itself at the minimum speed until it
reaches such threshold before switching off.
• If the boiler was shutdown regularly but, due to thermal inertia the smoke temperature exceeds the threshold again, the
shutdown stage restarts at the minimum speed until the temperature goes down.
12.17 BLACKOUT WITH THE BOILER ON
In the event of a power cut (BLACKOUT) the boiler behaves as follows:
• Blackout below 10”: it returns to its operation in progress;
• In the event of a power cut that lasts over 10” with the boiler on or in the start-up stage, when the boiler is powered again it
goes back to the previous operating condition with the following procedure:
1)
It cools down activating the smoke extractor at minimum power for 10’ and goes onto the next point;
1)
It takes the boiler back to the operating condition before the blackout.
During stage 1 the panel displays ON BLACK OUT.
During stage 2 the panel displays Start-up.
If during stage 1 the boiler receives commands from the panel and thus carried out manually by the user, then the boiler stops
executing the blackout recovery status and proceeds to restart or shutdown as requested by the command.
