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.
4.10.2.2. Operation by means of external thermostat
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
Connect the two wires coming from the wall-mounted thermostat to the
terminal of the MCZ connector.
Insert the connector in the socket located on the back of the stove.

Once the thermostat is connected, you will need to
disconnect the internal thermostat that the stove is
equipped with.
In order to do this, proceed as follows:
•
Press the button o immediately followed by the button p on the
control panel. The display of the control panel will show the
message UT01/OFF
• Press the button p repeatedly until the display on the panel shows
“ UT16"; the display of the control panel shows UT16
• Press and hold the button q and then press the button p and go
to item “UT20”; the display will show the message UT19/OFF
• Using the buttons n or o , set this parameter to “ON” or “OFF”. If
it is set to “ON”, the internal thermostat is enabled. Conversely, if it
the parameter is set to “OFF”, the external thermostat is enabled
and the internal one is disabled.
• Therefore, if you need to enable the external thermostat, you will
need to set parameter “UT20” to “OFF”.
To exit the menu, press the button r or wait 60 seconds
4.10.3. Setting of ECO-STOP mode
The thermostat manages stove operation by shutting the stove
down once the set temperature is reached and then lighting
again when this is necessary.
You can activate or de-activate this function, or select the intervals with
which the stove is to shut down.
