• Honeywell Standard Installation Adapter (J-box adapter)
  
• Honeywell Decorative Cover Plate – Small; size 4-49/64 in x 4-49/64 in x 11/32 in (121 mm x 121 mm x 9 mm)
  
• Screws and anchors
  
• 2 AA Batteries
  
• Installation Instructions and User Guide

Optional Cover Plate Installation

NOTE: If an Optional Cover Plate is not required, see “UWP Mounting System installation” on the next page.

Use the Optional Cover Plate when:

• Mounting the thermostat to an electrical junction box
  
• Or when you need to cover the paint gap from an old thermostat.

1. Separate the Junction Box Adapter from the Cover Plate. See Figure 1.
   
2. Mount the Junction Box Adapter to the wall or an electrical box using any of the eight screw holes. Insert and tighten the mounting screws supplied with Cover Plate Kit. Do not over-tighten. See Figure 2. Make sure the Adapter Plate is level.
   
3. 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 3.
   
4. Snap the Cover Plate onto the Junction Box Adapter. See Figure 4.
   UWP Mounting System Installation
   
   
5. Before starting, turn the power off at the breaker box or switch. Open the package to find the UWP. See Figure 5.
   
6. Position the UWP on the wall. Level and mark hole positions. See Figure 6. Drill holes at marked positions, and then lightly tap supplied wall anchors into the wall using a hammer. ‒ Drill 7/32” holes for drywall.
   
7. Pull the door open and insert the wires through the wiring hole of the UWP. See Figure 7.
   
8. Place the UWP over the wall anchors. Insert and tighten mounting screws supplied with the UWP. Do not over-tighten. Tighten until the UWP no longer moves. Close the door. See Figure 8. 

Power options 

Setting Slider Tabs

Set R Slider Tab.

• Use a 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 one wire is connected to the R terminal and one is 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 

Wiring terminal designations 

* Terminal can be jumped using Slider Tab. See “Setting Slider Tabs” above.

** The THP9045A1023 Wire Saver Module is used on heat/cool systems when you only have four wires at the thermostat and need a fifth wire for a common wire.

Use the K terminal instead 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.
