LEONARDO
is a combustion safety and control system which allows optimal performance in all
conditions thanks to two sensors measuring the pressure level in the combustion chamber and smoke
temperature.
The detection of and subsequent optimisation of these two parameters is continuous in order to correct
operation anomalies in real time.
The LEONARDO
®
system offers constant combustion, automatically regulating the draft based on the
characteristics of the chimney fl ue (bends, length, shape, diameter, etc..) and environmental conditions
(wind, humidity, atmospheric pressure, installations at high altitude, etc.).
The standards for installation must be respected.
®
LEONARDO
system is also able to recognise the type of pellets and automatically djust the fl ow mo-
ment by moment to ensure the required level of combustion.

SERIAL PORT
The Dealer can install an optional on the AUX outlet for controlling the process of switching on and
off (e.g. telephone remote, local thermostat), located at the rear oh the stove. Can be connected via
special optional trestle (code 621240). The serial port is located inside the coating on the left side.
BACKUP BATTERY
A backup battery is found on the control board (3-Volt CR 2032 battery). Its failure (not considered a
product defect, but normal wear and tear) is indicated with the words "Battery check". For more detai-
led information, please contact the DEALER who has performed the fi rst 1st ignition.
ROOM TEMPERATURE SENSOR
An outlet for the 1 metre-long room temperature cable is provided on the back of the stove. The sen-
sor, which will be attached to the wall using the bracket provided, is wired onto the end of the cable.
