UWP Mounting System installation

1. Open package to find the UWP. See

1

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.

3

‒ If your box contains red anchors, drill

7/32” holes for drywall. If your box
contains yellow anchors, drill 3/16”
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

4

Use 3x supplied

screws (#8 11/2
for red anchors and
#6 11/2 for yellow

anchors)

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.

Wiring UWP

Push down on the tabs to put the wires into the inner holes of their corresponding termi nals
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.

* The THP90 45A1098 C-wire adaptor 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 pl ace of the Y and
G terminals on conventional or heat pump systems to provide control of t he fan and the compressor
through a single wire—the unused wire t hen becomes your common wire . See THP90 45 instructions
for more information.

** Ventilation is not available on all models. When the U slider is in the dow n position (2 wires), the U

contacts are a dr y set of contac ts. If your ventil ation sy stem requires 24 volts, move the U slider to the
up position (1 wire). Lower U ter minal 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.

Setting Slider Tabs

Set R Slider Tab, see Figure 9.

• Use built-in jumper (R Slider Tab)
to differentiate bet ween 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
relay to wire ventilation. Please note
that ventilation is not suppor ted 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.

Wiring

NOTES:

1 Available wiring configurations differ by product models/product numbers.

2 Use 18 to 22 gauge thermostat wire. Shielded cable is not required.

3 Set the R Slider Tab on the UWP to the up position (1 wire) for 1 transformer

systems or the down position (2 wires) for 2 transformer systems. See "Setting
Slider Tabs" on page 4.

4 Set the U Slider Tab to the up position (1 wire) for non-powered ventilation or the

down position (2 wires) for powered ventilation. See "Setting Slider Tabs" on page
