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.

‒ If your box contains red anchors, use

a 7/32” drill bit. If your box contains yellow anchors, use a 3/16” drill bit.

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

Optional 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.

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 THP9045A1098 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 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 THP90 45 instructions for more information.

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) for IAQ device.

• When the U Slider Tab is in the down position (2 wires) the U contacts are a dry set of contacts.

• If your IAQ device is powered by the cooling transformer, move the U Slider Tab to the up position (1 wire). When this is done, the lower U terminal is internally jumped to the Rc terminal. In this application, you would hook up one wire from your IAQ device to the upper U terminal and the other to the common side of the cooling transformer. The 1 wire setting is most commonly used when using a fresh air damper for ventilation or using low speed fan for dehumidification.

• See wiring examples on the next page.

NOTES:

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

2. 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.

3. Set the U Slider Tab as shown in the diagrams on page 4.

Mounting thermostat

1. Push excess wire back into the wall opening.

2. Close the UWP door. It should remain closed without bulging.

3. Align the UWP with the thermostat, and push gently until the thermostat snaps in place.

Note: If you used the Optional Cover Plate shown on page 2, remove the gray trim ring from the thermostat before step 3. Then align the thermostat with cover plate and push gently until the thermostat snaps into place.

Note: If needed, gently pull to remove the thermostat from the UWP
