4.10.2.1. Internal thermostat - Position of internal room sensor

Only when installation is complete, be sure to check that the
room probe is removed from its place and set far away from
the stove, to prevent it from detecting incorrect temperatures.
The probe is located on the back part of the stove.
When you use the internal thermostat, you should always set a
temperature that is a few degrees higher (for example, if you want to
attain 20°C you should set to 22°C) because the probe is affected by
the heat from the body of the stove.

EXTERNAL THERMOSTAT (not included with the stove, to be
provided by the user)
The temperature of the stove can also be controlled by an external
room thermostat. It is located in a central position of the room where
the stove is installed. It provides a closer match between the heating
temperature requested of the stove and what it actually provides.

4.10.2.3. Connection of external thermostat
