4.7.1Replacing the battery
The remote control is powered by a 3-volt CR2025 type battery located in the bottom of the device. For its insertion
and possible replacement, proceed as follows:
- Operate the lever indicated;
- Pull out the battery tray and replace the battery ( 3-volt CR2025 model ) respecting the polarity;
- Insert the tray;
- Check proper functioning.
- Keep the remote control away from direct heat sources and water.
- The remote control battery must be replaced and disposed of safely in compliance with local
Regulation:

4.8 Thermostat - external chronothermostat

The standard unit controls the room temperature by means of a digital probe that adjusts the power according to the
set temperature.
To use an additional thermostat, contact an authorised technician and proceed as follows:
turn off the power at the main switch (if available) and disconnect the power cable;
remove the panels to gain access to the main board;
referring to the wiring diagram, connect the two thermostat wires to the respective terminals TERM on the
board (use a 'normally open' type thermostat);
refit everything and check proper functioning
Then set as follows:
−
external thermostat: set a temperature of 7°C;
−
external chronothermostat: set a temperature of 7°C, disable the chrono functionality in the menu 03 and
set the STANDBY function to ON. When the set temperature is reached, the stove will shut down and not
go to modulation.
In this case, however, it is advisable to use the stove time programming function and only the external
chronothermostat set temperature function.
In fact, only with this joint setting is it possible to set STANDBY to ON or OFF, obtaining respectively
modulation or shutdown when the SET temperature is reached and likewise obtaining shutdown and lighting
according to the set time programming.
When the external thermostat requests stove operation, the corresponding symbol will light up on the display.

4.9 Idle period (end of season)

If the stove 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 and remove the power cable;
- clean thoroughly and, if necessary, have any damaged parts replaced by qualified personnel;
- protect the stove from dust with suitable covering;
- store in a dry and safe place protected from 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.
