• Away from drafts caused by doors, windows,
outside walls, air registers, return air
plenums, and so on.
• Away from heat sources such as strong
lights, fireplaces, direct sunlight, and son on.
• On an inside wall, about 5 feet (1.5 m) above
the finished floor.
2. Mount the WRS base plate to the wall.
• If used, leave sufficient room to install the
Lockable Thermostat Guard. See the
Lockable Thermostat Guard Technical
Instructions (155-723).
• If mounting to drywall, see Drywall Base-
Plate Mounting for instructions.
3. Snap the sensor front to the sensor base plate
by first hooking the sensor front to the top
latches, and then rotating the cover downward
until it latches.
4. Loosen the safety set screw at the bottom of
the base one or two revolutions to lock the
cover to the base. Be careful not to loosen too
far as the screw can be completely removed
from the base.
NOTE: There is a perforated label containing
the 16-digit EUID number on the back
of the WRS. It can be removed and
placed on a schedule to facilitate future
commissioning of a replacement WRS
device, if required.
Drywall Base-Plate Mounting (Figure 2)
1. Using the sensor base plate as a template, mark
the top and bottom mounting hole locations for
drywall mounting.
2. Drill two 3/16-inch (4.8 mm) mounting holes and
mount the two wall anchors.
3. Orient the UP arrow on the base plate at the top
and mount on the wall as follows:
a. Level the sensor base plate.
b. Tighten the two mounting screws to the
sensor base plate.
CAUTION:
Over-tightening may cause the sensor
base plate to crack or bend.
Optional Guard Mounting
If used, install per the Lockable Thermostat Guard
Technical Instructions (155-723).
The installation is now complete.
