Installing Wall Models HMW82/83 and

TMW82/83

REQUIRED

TOOLS

- Small flat head screwdriver for opening the transmitter and for

screw terminals.

- Two screws, max Ø 4 mm.

- Depending on the wall material and screw type, you may need a

drill and a suitable drill bit to make installation holes for screws.

- Tools for cutting and stripping wires.

1. Use a flat head screwdriver to push down the tab on top of the

transmitter and separate the mounting base from the transmitter

cover.

2. Use the mounting holes to attach the mounting base securely. Use

at least two screws (not included, max Ø 4 mm).

NOTE

The arrow on the mounting base must point straight up after installation.

Proper orientation is important:

air must flow through the vents on the

bottom and top.

3. Route the power and signal cable to the screw terminals and

connect the wires. Refer to section Wiring on page 26.

4. Close the transmitter cover when done.
