13-SAFETY DEVICES
NORMAL SHUTDOWN (on the panel: OFF with ashing ame symbol)
When the shutdown key is pressed, or when there is an alarm signal, the stove enters the thermal extinguishing phase which involves
automatic execution of the following phases.
• Stop pellet loading
• The room fan maintains the set speed until reaching the switch-o temperature
• The smoke extractor fan is activated at maximum speed and remains on for a xed period of 10 minutes, at the end of which if the
smoke T has dropped below the stop threshold, the fan stops, otherwise it will continue to operate at minimum speed until the
temperature drops below the threshold.
• If the stove has been shutdown regularly but, due to thermal inertia, the smoke temperature exceeds the threshold again, the
shutdown phase will be repeated at minimum speed until the temperature drops.
BLACKOUT WITH STOVE ON
In the event of a blackout, the stove does the following:
• Power failure of less than 10”: continues the work in progress;
• After a loss of power of more than 10’’ which occurred when the stove was on, or during ignition, you can restore the stove to its
previous operating condition when power returns as follows:
1. Cool the boiler by activating the smoke extractor at minimum speed for 10’ then proceed to the next step;
2. Restore the stove to the operating condition prior to the blackout.
During phase 1, the panel shows ON BLACK OUT.
During phase 2, the panel shows Start-up.
If during phase 1 the stove receives manual user commands from the control panel, it stops the blackout restoration sequence and begins
the start-up or shutdown commanded by the user.
BLACKOUT OF MORE THAN 10’’ DURING EXTINCTION OF STOVE
If the stove experiences a loss of power GREATER THAN 10” while it is shutting down, when power is restored to the stove, it will
automatically turn on in shutdown mode, even if the smoke temperature has fallen below 45°C in the meantime. This phase can be
skipped by pressing key 1 (esc) (skips to start-up) and pressing it again (recognises that the stove is o).
BLACKOUT OF MORE THAN 10’’ WITH THE STOVE OFF FROM ECOSTOP
Once power has been restored, a 5-minute timer is set as though the stove were in switch-o mode; should there be a request for heat in
these 5 minutes, the stove will not start.
SAFETY DEVICES ALARM A05
The safety devices alarm includes the intervention of the smoke pressure switch, of the fuel loading hatch and of the open stove door.
The alarm will be triggered after 30 seconds, after which the stove will stop working (e.g. after 30 seconds with the pellet loading hatch
open, alarm A05 will be triggered).
