Optional probe and external thermostat
The standard unit controls the room temperature by means of a probe that adjusts the power according to the set
temperature.
The probe is positioned in the remote control and measures the temperature in the place where the remote control
is located. The user can choose to use an external thermostat or an optional probe, connected directly to the
motherboard, whose sensor can be located in the most suitable place.
In case of an external thermostat, it is necessary to use a 'normally open' type. Contact an authorized technician
and follow the following instructions:
-
turn the unit off at the main switch and disconnect the power cable;
-
remove the insert from the compartment and access the motherboard;
-
referring to the wiring diagram, connect the two thermostat wires to the respective terminals TERM of the board;
-
refit everything, then set REMOTE PROBE in menu 10;
-
Then set as follows:

in case of external thermostat: Set a temperature of 7°C on the remote control and adjust the external
thermostat setting as desired;

in case of external chronothermostat: Set a temperature of 7°C on the remote control and adjust the
external chronothermostat setting as desired.
It is compulsory to disable the chrono function in menu 03 and set the STANDBY function to ON. When the
set temperature is reached, the insert will shut down and not go to modulation.
In any case, it is advisable to use the insert time programming function and only the external
chronothermostat setting function. This will avoid creating conflicts between the insert programming and
that of the chronothermostat
-
Check correct operation.
In case of an optional probe, contact an authorized technician and proceed as follows:
-
turn the unit off by disconnecting the power cable or by using the external switch;
-
remove the insert from the compartment and access the motherboard;
-
referring to the wiring diagram, connect the two wires of the probe to the respective terminals N.AMB of the
board and place the probe head in the position deemed most appropriate;
-
refit everything and then set LOCAL PROBE in menu 10;
-
check correct operation.

Idle period (end of season)
If the insert is not used for long periods, and/or at the end of each season, it is advisable to proceed as follows
- remove all the pellets from the hopper;
- disconnect the power supply by disconnecting the power cable or by using the external switch;
- clean thoroughly and, if necessary, have any damaged parts replaced by qualified personnel;
- in case of removal of the insert, arrange it in a safe and dry place, protected from the atmospheric agents.
5 STOVE CLEANING
Stove cleaning is very important to ensure correct operation and to prevent: blackening of the glass, poor
combustion, deposits of ash and unburnt products in the brazier, reduced thermal efficiency.
The stove must only operate with the fire door closed.
The fire door seals must be checked periodically to prevent any air from entering; the combustion chamber and
pellet duct work in a negative pressure and the fume exhaust in a positive pressure.
Routine cleaning is normally carried out by the customer following the instructions in the manual, whereas
extraordinary maintenance, at least once a year, must be performed by the authorised Service Centre.
- Cleaning operations for all parts must be carried out with the stove unplugged and
cold;
- Dispose of cleaning waste in accordance with the current local regulations;
- The stove must not be operated without its cladding;
- Avoid the creation of smoke and unburnt products during lighting and/or normal operation.
Given below are the control and/or maintenance operations for correct stove use and operation.
