• The room unit must be located around 1.5 metres from the floor, in a part of the room where the sensor can measure the room
temperature as precisely as possible; it must be sheltered from streams of cold air, sunlight or other sources of heat.
• If mounted on the wall, at the top of the room unit there must be enough space for assembly and removal when necessary.
The room unit, once removed from its base, is no longer powered and consequently is not working.
