A5 room controller connection
Installation instructions
The room controller must be installed in the best reference
position for temperature control.
Position the room controller as follows:
• around 1.5 metres from the floor, in a part of the room that
allows the sensor to accurately measure the room temper-
ature;
• away from cold air flows, sunlight or other sources of heat.
• leave enough space above the room controller to allow
assembly and removal where necessary.
• If the room controller is removed from its base, it discon-
nects from the power supply and consequently is no
longer operating.
