Installing the room unit
Choosing a location
Since the temperature measurement sensor is inside the unit, you must
install the thermostat flush-mounting box:
- in zone 1 (main room) only,
- on an accessible wall at a height of 1.50 m,
- away from heat sources (fireplaces, sunlight) and draughts (windows,
doors).
IMPORTANT: Do not install the thermostat on a wall in contact with the out-
doors or with an unheated room (e.g. garage, etc.).
The sleeve output in the flush-mounting box must be plugged (with mastic)
in order to avoid unwanted air movements that would cause the sensor rea-
ding to be inaccurate.
