Installation and commissioning of the control

unit

Putting the control unit into operation
The control unit uses wireless frequencies. It therefore offers
flexibility in terms of selecting a position. Connection of cables
is not required.
Air must be able to circulate freely round the control unit and it
must be installed on an open surface unhindered by curtains or
furniture. The control unit must not be positioned closer than
300 mm to metal objects, including wall-mounted metal boxes.
Do not mount the control unit on a wall where it will be exposed
to sunlight or draughts, preferably on an inside wall 1.2 m
above the floor.
