Mounting Information

Always mount the room unit vertically.
Locate the room unit:

• according to design specifications and local
regulations.

• where the air circulates around it freely (not in
recessed areas or behind doors).

• allowing a minimum of 4 inches (10 cm) free
space above and below for proper airflow, the
front cover removal tool, and the computer
communicati on cabl e.

• away from drafts caused by doors, windows,
outside walls, air registers, pipes, return air
plenums, etc.

• away from heat sources such as strong lights,
fireplaces, direct sunlight, etc.

• on an inside wall (preferably), about 5 feet
(1.5 m) above the finished floor, or per code
(ANSI, ADA, or local regulation).

Drywall Mounting (No Rough-in),
Typical

Base Plate Mounting and Wiring

1. Mark the center (cable) hole and the mounting hole
locations, using t he room unit base plate as a
template. See Figure 3.

Figure 2. Insulating Gasket.

4. Pull about three inches (75 mm) of the cable through
the hole in the base plate.

5. Mount the room unit base plate on the wall, noting
the UP arrow:

NOTE: If required, position the back plate behind

the room unit base, aligning the top and
bottom mounting holes, prior to mounting
to the wall:

a. Install the two mounting screws prov ided, but

do not tighten.
b. Level the room unit base plate for appearance.
c. Ti ghten the two mounting screws to the room

unit base plate.

6. Cut the cable, leaving about three inches (75 mm)
on the room unit side of the drywall. Ensure that pin
Number 1 connects to the same wire at each end of
the cable.

2. Drill two 3/16-inch (4.8 mm) mounting holes and
mount the two plastic wall anchors flush to below the
wall surface for stable mounting of the device.

3. Cut a 1-inch (25 mm) center hole with a hole saw.

NOTE: It is recommended that you use the

optional Insulating Gasket* on the back
of the Unit Base for hollow wall
install ati ons.

When applying the adhesive-backed
gasket to the back of the unit base, orient
the gasket so that the cut-out arrow
portion of the gasket is in the upper
lefthand quadrant of the unit base. The
sensor base has an UP arrow mol ded
into the surf ace in the same quadrant
location (see Figure 6).

*Insulating gasket s are sold in 10-packs
(Part Number 563-102 GSKT KIT).
