Multiple programming options that fit your lifestyle:

1. Location-Based scheduling: The thermostat uses your smartphone's location to know when you're away, saving energy. Through geofence technology, it senses your return and helps make you comfortable upon arrival. You can always manually change your preset Home and Away temperature either on the thermostat or on the Honeywell Home app.
2. Smart scheduling: Use a combination of geofencing and time scheduling to fit your busy, active lifestyle.
3. Time-Based scheduling: Program your thermostat for one week; each day can have a different schedule; options include Mon-Fri, Sat, Sun; or Mon-Fri, Sat-Sun. All days support four adjustable periods per day.
4. No scheduling: Control your comfort manually by adjusting temperature set points only.

Removing your old thermostat

Step 1: Turn power OFF

To protect yourself and your equipment, turn off the power at the breaker box or switch that controls your heating/cooling system.

Diagram: Breaker box with a switch shown in the OFF position. A finger is depicted pressing the switch to OFF.

Step 2: Check that your system is off

Change the temperature on your old thermostat. If you don't hear the system turn on within 5 minutes, the power is off.

Note: If you have a digital thermostat that has a blank display, skip this step.

Diagram: A thermostat display showing "75".

Step 3: Remove your old thermostat from the wall plate

On most thermostats, you can take off the thermostat by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps.

Do not remove any wires from your thermostat at this time! [alert-icon]

Diagram: A hand grasping and gently pulling a thermostat off a wall plate.

Step 4: Make sure there are no 120/240V wires

Do you have thick black wires with wire nuts? Is your thermostat 120V or higher? If you answered yes to either of these questions, you have a line voltage system and the thermostat will not work.

If you are unsure visit: honeywellhome.com

Step 5: Take a picture of how your wiring looks right now

Be sure to include the letters next to the terminals where the wires are inserted. This will be a helpful reference when wiring your thermostat.

Tip: If the color of your wires has faded or if 2 terminals have the same wire color, use the wire labels provided in the package to label each wire.

Diagram: A smartphone taking a picture of thermostat wiring, showing terminals labeled with letters.

Step 6: Remove any jumpers

A jumper connects one terminal to another terminal. It may look like a small staple or even a colored wire and must be removed before continuing. Use a screwdriver to release wires from the terminal.

Diagram: An example of a jumper connecting terminals labeled 'R' and 'RC'.

The thermostat does not need jumpers.

Step 7: Record if you have wires in the following terminals

Do not include jumpers as a part of your count. The thermostat does not need jumpers.

Step 8: Write down the color of the wires

Check mark the wires that are connected to terminals. Next to the check mark, write down the color of the wire. Do not include jumpers as a part of your count.

Check all that apply (Not all will apply):

S and U terminals are not supported with this thermostat.

If there are wires in terminals that are not listed, you will need additional wiring support. Visit honeywellhome.com to find out if the thermostat will work for you.

Step 9: Disconnect the wires and remove the old wall plate

Use a screwdriver to release wires from terminals.

Tip: To prevent wires from falling back into the wall, wrap the wires around a pencil.

Installing your T5 Smart Thermostat

Step 10: Bundle and insert wires through the UWP

Pull open the UWP and insert the bundle of wires through the back of the UWP. Make sure at least 1/4-inch of each wire is exposed for easy insertion into the wire terminals.

Diagram: UWP with wires being inserted through the back. A close-up shows wire ends exposed 1/4" to 3/8".

Step 11: Insert the wall anchors

It is recommended that you use the wall anchors included in the box to mount your thermostat. You can use the UWP to mark where you want to place the wall anchors.

• a) Level the wall plate.
• b) Mark the location of the wall anchors using a pencil.
• c) Drill the holes.
• d) Insert wall anchors.
• e) Make sure anchors are flush with the wall.

Tip: Use a 7/32 drill bit.

Step 12: Set R-switch position and insert R-wire or wires

Set the R-switch up or down based on your wiring notes in Step 7. Insert wires into the inner holes of the terminals on the UWP. The tabs will stay down once the wire is inserted.

If you have 1 R-wire (R, Rh, or Rc):

1. Set R-switch to the up position.
2. Insert your R-wire (R, Rh or Rc) into R-terminal.

Diagrams showing R-switch in the UP position and wire insertion into the R-terminal.

If you have 2 R-wires (R or Rh, and Rc):

1. Set R-switch to the down position.
2. Insert your Rc wire into Rc-terminal.
3. Insert your R or Rh wire into R-Terminal.

Diagrams showing R-switch in the DOWN position and wire insertion into Rc and R terminals.

Step 13: Connect remaining wires from Step 8

Do not mount the UWP to the wall prior to connecting the wires. Depress the tabs to put the wires into the inner holes of their corresponding terminals on the UWP (one wire per terminal) until it is firmly in place. Gently tug on the wires to verify they are secure.

Tip: If you need to release the wires again, push down the terminal tabs on the sides of the UWP.

Diagram: Wires being inserted into UWP terminals, hand tugging wires to verify security, and arrows indicating terminal tabs that can be pushed to release wires.

Step 14: Mount the UWP and close the door

Mount the UWP using the provided screws. Install all three screws for a secure fit on your wall. Close the door after you're finished.

Step 15: Attach your thermostat

Align the thermostat onto the UWP and firmly snap it into place.

Diagram: Thermostat being attached to the UWP, with a 90-degree angle indicator.

Step 16: Turn your power ON

Turn on the power at the breaker box or switch that controls the heating/cooling system.
