Preparation

Installation site
The length of the bus cable between the programming unit and ventilation unit must not exceed 20 m.
Observe the following installation location requirements to ensure correct function.

F it the appliance to an internal wall, but not in a recess.

Never cover the appliance with curtains, etc.
E nsure the device is not directly exposed to external heat sources (e.g. the sun, central heating or a TV set).
Avoid direct draughts coming from windows and doors.

Installation

For installation, remove the appliance from the wall mounted enclosure:

Release the locking tab found in the opening on the under-side of the wall mounted enclosure. Press the locking tab with a screwdriver.

Installation as an external programming unit
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.

Make sure that the screws supporting the flush box are arranged either vertically or horizontally opposite one another.
Route the bus cable through the aperture in the wall-mounted enclosure from the back.

Installation without a flush box

To secure the wall-mounted enclosure, drill four holes (Ø 5 mm).
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 mounting enclosure), a reservoir needs to be made to hold 20 to 30 cm of data cable.

Break out one of the knock-outs in the wall-mounted enclosure.

Route the bus cable through the aperture from the back.

Installing the wall mounted enclosure

Flush box
Secure the wall mounted enclosure to the flush box or to the wall using the screws provided.
