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.
