Honeywell T6 Pro Installation Instructions

T6 Pro

Programmable Thermostat

Installation Instructions

Package Includes:

• T6 Pro Thermostat

• UWP Mounting System

• 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 Optional Cover Plate is not

required, see “UWP Mounting System installation” on next page.

Use the Optional Cover Plate when:

• Mounting the thermostat to an electrical junction box

• Or when you need to cover paint gap from 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 mounting screws supplied with Cover Plate Kit. Do not overtighten. 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 package to find the UWP. See Figure 5.

6. Position the UWP on 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 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 overtighten. Tighten until the UWP no longer moves. Close the door. See Figure 8.

Use 3x supplied

screws #8 11/2”

Power options

L/A

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.

O/B

AUX

Insert AA batteries for primary or backup power.

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 T6 Pro models.

Note: Not all

terminals may be

used, depending

on the system

type that is being

wired. The most

commonly used

terminals are

shaded.

* 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 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.
