4.17 ROOM TEMPERATURE REACHES THE SET
TEMPERATURE
When the room temperature or the flue gas temperature have
reached the set value, the heat output is automatically
brought to the minimum value “MODULATION" condition, see
fig. 30.
fig. 30 control panel - set temperature modulation
If STAND-BY mode is activated, the stove switches off with a
delay equal to the time preset by the manufacturer after hav-
ing reached the set temperature.
The stove restarts after the room temperature
drops below the set temperature for an amount
of time preset by the manufacturer.T

4.18 CLEANING THE BRAZIER
During standard operating conditions, the “BRAZIER CLEAN-
ING” mode is activated at intervals established by the manu-
facturer for a preset amount of time.

4.19 SWITCH-OFF
To switch the stove off, just press the button (4) for about 2
seconds. The auger stops immediately and the flue gas extrac-
tor is brought to high speed. "FINAL CLEANING" is carried out.
When the flue gas temperature has dropped to a value set by
the manufacturer, the flue gas extractor is disabled after a pre-
set amount of time.

4.20 RESTART
The boiler cannot be restarted until the flue gas temperature
drops below the preset value for the set amount of time.
Always clean the brazier before restarting.

4.21 FUNCTIONS OF MECHANICAL AND
ELECTRIC COMPONENTS
Auger motor
The auger motor drives the screw
which brings pellets from the tank
to the brazier.
Flue gas extraction motor
The flue gas extraction motor fixed
to the extraction turbine, placed
at the back of the stove, suctions
and expels flue gas formed in the
combustion chamber. This provides
perfect combustion and improved
heating performance.
Circuit board
The circuit board guarantees cor-
rect operation and the maximum
safety of the boiler in managing all
its functions.
Main switch
Electronic component of the boiler
consisting of a 4A fuse and an elec-
tronic filter which protect the boiler
from electric overloads and electro-
magnetic interference.
Smoke sensor
The flue gas sensor detects the flue
gas temperature in the extraction
turbine and is triggered when it
reaches 270°C, bringing the boiler
to energy-saving mode (“RIS”).
