Optional Cover Plate installation

NOTE: If Optional Cover Plate is not required, see “UWP Mounting System installation”.

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.
   

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:

3. Position the Cover Plate on wall. Level and mark hole positions.

4. 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).

UWP Mounting System installation

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.
   

Power options

• Insert R and C wires 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.
  
  

Setting Slider Tabs

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 T1 Pro models.
