EXTERNAL THERMOSTAT
Description Display message
Stove operation can be controlled by an external room thermostat (normally open) connected to the power board.
For thermostat connection see the table "INSTALLATION OF EXTERNAL ROOM THERMOSTAT”.
The ENERGY SAVING mode cannot be activated if the external thermostat is set on STOP and vice-versa.
Operation of the external thermostat is conditioned by the appliance set temperature.
To enable the external thermostat:
- set the desired room temperature on the external thermostat.
- Set the maximum value of 30°C on the stove.
The display shows the time (e.g..10:30) or the room temperature, according to the initial settings and
the power set (e.g.. P2).
