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, and so on.
• away from heat sources such as strong lights,
fireplaces, direct sunlight, and so on.
• 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 the temperature sensor 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 provi ded, but do
not tighten.
b. Level the room unit base plate for appearance.
c. T ighten the two m ounting 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 dev ice.
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 Sensor Base for hollow wall
install ati ons.
When applying the adhesive-backed
gasket to the back of the Sensor Base,
orient the gasket so that the cut-out
arrow portion of the gasket is in the
upper left-hand quadrant of the Sensor
Base. The Sensor Base has an UP
arrow molded into the surface in the
same quadrant location (see Figure 6).
NOTE:See Figure 2 for details on optional Gasket
application.
