PlC ASSOCIATION/dISSOCIATION
Your appliance can be controlled remotely by a
PLC (Powerline Carrier) programming base unit using
the X2D protocol. To use this facility, remove the cover
and insert the Powerline Carrier interface module (op-
tion, please contact your installer or dealer) in its place.

3.7 Calibrating and dissociating the Comfort and eco
temperatures
The calibration facility can be used to correct any variation between the room
temperature achieved by the appliance and the setpoint temperature requested at the
thermostat.
To do this, enter the variation between the temperature measured by a thermo-
meter in the room and the temperature achieved in COMfORT mode.
Hold the Boost and – buttons on for 5 seconds. The screen shows "0".
The thermostat will then allow the measured temperature reading to be chan-
ged by up to + or - 5°C in 0.5°C increments by pressing the + and – buttons.
Then press the Boost button to switch to eCO mode temperature association/
dissociation.
Press the + and – buttons to select:
- Of: The eCO mode temperature is your chosen comfort mode temperature
minus 3.5°C.
- ON: The eCO mode temperature can be set independently of the COMfORT
mode temperature. In eCO mode, you can now press the + and – buttons to increase
or reduce the temperature in 0.5°C steps.
Press the Boost button to exit.
