Optional Cover Plate installation
NOTE: If Optional Cover Plate is not
required, see “UWP Mounting System
installation” on next page.
Use the Optional Cover Plate when
you need to cover paint gap from old
thermostat.
There are different cover plates
depending on when the thermostat was
manufactured.
For the square cover plate:
1. Separate the Cover Plate from
Mounting Plate.
2. Mount the Mounting Plate on to the
wall using any of the 8 screw holes.
Insert and tighten mounting screws
supplied with Cover Plate Kit. Do not
overtighten. See Figure 2. Make sure
the Mounting Plate is level.
3. Attach the UWP by hanging it on the
top hook of the Mounting Plate and
then snapping the bottom of the UWP
in place. See Figure 3.
4. Snap the Cover Plate onto the
Mounting Plate. See Figure 4.
Use supplied
screws and
wall anchors

UWP Mounting System installation
Use 3x supplied
screws (#8 11/2
for red anchors and
#6 11/2 for yellow
anchors)
1. Before starting, turn the power off
at the breaker box or switch. Open
package to find the UWP. See Figure 1.
2. Position the UWP on wall. Level and
mark hole positions. See Figure 2.
Drill holes at marked positions, and
then lightly tap supplied wall anchors
into the wall using a hammer.
‒If your box contains red anchors,
drill 7/32” holes.
‒If your box contains yellow anchors,
drill 3/16” holes.
3. Pull the door open and insert the wires
through wiring hole of the UWP. See
Figure 3.
4. Place the UWP over the wall anchors.
Insert and tighten mounting screws
supplied with the UWP. Do not
overtighten. Tighten until the UWP
no longer moves. Close the door. See
Figure 4.

For the rectangular cover plate:
1. Mount the Cover Plate on the wall using
any of the 6 screw holes. Insert and tighten
the mounting screws supplied with the
Cover Plate. Do not overtighten. See Figure
1. Make sure the Cover Plate is level. Attach
the UWP by hanging it on the top hook
of the Cover Plate and then snapping the
bottom of the UWP in place. See Figure 2.
2. If there are no existing wall anchors:
a. Position the Cover Plate on wall. Level
and mark hole positions. See Figure 1.
b. Drill holes at marked positions, and then
lightly tap supplied wall anchors into the
wall using a hammer.
•If your box contains red anchors, drill
7/32” (5.6 mm) holes.
•If your box contains yellow anchors,
drill 3/16” (4.8 mm) holes.
•Use 2x supplied screws (#8 11/2”
(38 mm) for red anchors and #6
11/2” (38 mm) for yellow anchors).

terminals are
shaded.
* Terminal can be jumped using Slider Tab. See “Setting Slider Tabs” above.
Set R Slider Tab.
• Use built-in jumper (R Slider Tab)
to differentiate between one or two
transformer systems.
• If there is only one R wire, and it is
connected to the R, Rc, or RH terminal, set
the slider to the up position (1 wire).
• If there is one wire connected to the R
terminal and one wire connected to the Rc
terminal, set the slider to the down position
(2 wires).
NOTE: Slider Tabs for U terminals should be
left in place for T6 Pro models.
Setting Slider Tabs
Insert Rand Cwires into
designated terminals
for primary AC power (C
terminal is optional if
batteries are installed,
but it is recommended).
Remove wires by
depressing the terminal
tabs.
Insert AA
batteries for
primary or
backup power.
