UWP Mounting System installation
1. Open package to find the UWP. See
Figure 1.
2. Position the UWP on the wall. Level and
mark hole positions. See Figure 2.
Drill holes at marked positions, and
then lightly tap supplied wall anchors
into wall using a hammer.
‒Drill 7/32” holes for drywall.
3. Pull the door open and insert 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.

Optional Decorative Cover Plate installation
Use the Optional Cover Plate when:
• Mounting the thermostat to an
electrical junction box
• Or when you need to cover paint gap
from the old thermostat.
5. Separate the Junction Box Adapter
from the Cover Plate. See Figure 5.
6. Mount the Junction Box Adapter to
the wall or an electrical box using any
of the eight screw holes. Insert and
tighten mounting screws supplied with
Cover Plate Kit. Do not overtighten.
Make sure the Adapter Plate is level.
See Figure 6.
7. Attach the UWP by hanging it on the
top hook of the Junction Box Adapter
and then snapping the bottom of the
UWP in place. See Figure 7.
8. Snap the Cover Plate onto the
Junction Box Adapter. See Figure 8.

* The THP9045A1023 Wire Saver Module is used on heat/cool systems when you only have four wires
at the thermostat and you need a fifth wire for a common wire. Use the K terminal in place of the Y and
G terminals on conventional or heat pump systems to provide control of the fan and the compressor
through a single wire—the unused wire then becomes your common wire. See THP9045 instructions
for more information.
** Ventilation is not available on all models. When the U slider is in the down position (2 wires), the U
contacts are a dry set of contacts. If your ventilation system requires 24 volts, move the U slider to the
up position (1 wire). Lower U terminal is internally jumped to the Rc terminal. In this application, you
would hook up one wire from your damper to the upper U terminal and the other to the common side of
the transformer.
Wiring UWP
Push down on the tabs to put the wires into the inner holes of their corresponding terminals
on the UWP (one wire per terminal) until they are firmly in place. Gently tug on the wires to
verify they are secure. If you need to release the wires again, push down the terminal tabs
on the sides of the UWP.
This wiring is just an example,
yours may vary.

Setting Slider Tabs
Set R Slider Tab, see Figure 9.
• 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
on the old thermostat, 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).
Set U Slider Tab, see Figure 10.
• Use built-in jumper (U Slider Tab)
of universal relay to wire ventilation.
Please note that ventilation is not
supported on all models.
• When the U Slider Tab is in the down
position (2 wires) the U contacts are a
dry set of contacts.
• If the ventilator is powered by the
cooling transformer, move the jumper
switch to the up position (1 wire). With
this switch set to 1 wire, the lower U
terminal is internally jumped to the Rc
terminal. In this application, hook up
one wire from the vent damper to the U
terminal and the other to the common
side of the cooling system transformer.
