Wall installation

For restricted spaces you can detach the controller
from the VAV terminal unit and install it on the wall
next to the terminal unit or anywhere else nearby; to
fix the controller on a wall, you can use a mounting
bracket (Part no. E346GL3).

Do not extend the actuator cable or any measuring
tubes.

Be sure to install the controller according to the
sticker showing the correct installation orientations

Fig. 8: Detaching the controller

1.

Use a screwdriver to flip up the lug (1) and
lift the controller.

In some cases, e.g. with TVLK, the controller
is factory fitted to the terminal unit without a
bracket.

2.

Use suitable screws 

 4 mm to fix the

mounting bracket to the wall.

3.

Press the controller casing as shown onto
the mounting bracket until it clicks into place.
