INSTALLER CONNECTIONS TO BE PERFORMED ON THE INSIDE MODULE

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.
