| FEB 2.1
f Fit the appliance to an internal wall, but not in a recess.
f Never cover the appliance with curtains, etc.
f Ensure the device is not directly exposed to external heat
sources (e.g. the sun, central heating or a TV set).
f Avoid direct draughts coming from windows and doors.
8.
Installation
For installation, remove the appliance from the wall mounted
enclosure:
A
f Release the locking tab found in the opening on the under-
side of the wall mounted enclosure. Press the locking tab
with a screwdriver.
8.1
Installation as an external programming unit
f Route a 4-core bus cable from the ventilation unit to the
mounting position of the programming unit. Use a screened
electronic cable such as LiYCY 2x2x0.8 mm². Do not route the
cable parallel to a three-phase cable.
The BUS cable must protrude 20 to 30 cm out of the wall to allow
installation.
Installation with a flush box
For securing to a wall we recommend using a flush box, which can
hold the part of the bus cable protruding from the wall.
f Make sure that the screws supporting the flush box are ar-
ranged either vertically or horizontally opposite one another.
f Route the bus cable through the aperture in the wall mount-
ed enclosure from the back.
Installation without a flush box
f To secure the wall mounted enclosure, drill four holes
(Ø 5 mm).
f When routing the BUS cable, be careful not to damage the
cable when drilling the fixing holes.
In the area around the power cable entry (behind the wall mount-
ing enclosure), a reservoir needs to be made to hold 20 to 30 cm
of data cable.
B
f Break out one of the knock-outs in the wall mounted
enclosure.
f Route the bus cable through the aperture from the back.
