Installing your thermostat
You might need the following tools to install this thermostat:
- No. 2 Phillips screwdriver
- Pen
- Pencil
- Level (optional)
- Drill and bits (3/16” for drywall, 7/32” for plaster)(optional)
- Hammer (optional)
- Electrical tape (optional)
Switch OFF power to your heating/cooling system.
Important! To protect your equipment, switch OFF the power to your heating/cooling system at the breaker box or the system switch.
Remove old thermostat faceplate and leave wires connected.
- 2a Take a picture of the wire connections for later reference.
- 2b If no wire is connected to a terminal labeled C or no C terminal exists on the old thermostat, view the Alternate Wiring videos at honeywellhome.com/wifithermostat or reference the C-wire addendum in the box.
Important! C wire is required and is the power source for your thermostat. Without a C wire, your thermostat will not power up.
Note: You will need a picture of your wire connections to wire the new thermostat.
Installing your thermostat
- Label the wires. Use the supplied sticky tags to label each wire as you disconnect it. Label wires according to the old thermostat terminal designations, not by wire color.
Note: If no tag matches a terminal designation, write the appropriate letter on a blank sticky tag. - Remove wallplate. Remove the old wallplate from the wall after all wires have been labeled and disconnected.
- Mount wallplate for thermostat. Mount your new wallplate using screws and anchors included with the thermostat.
If necessary: Drill 3/16-in holes for drywall. Drill 7/32-in holes for plaster.
Note: Wrap the wires around a pencil to prevent them from falling back into the wall.
Installing your thermostat
Important! This thermostat requires a C, or common, wire for power. The C, or common, wire brings 24 VAC power to the thermostat. If you are replacing an existing thermostat, it might not have a C wire connected to it. Many older mechanical or battery operated thermostats do not require a C wire. See the C Wire Addendum document included in this package for more information.
Note: Not all heating/cooling systems label the 24 VAC common C. Check your system manual or contact the manufacturer to find out which terminal is the 24 VAC common.

Wiring
- For conventional heating/cooling systems (natural gas, oil or electric furnace, air conditioner). “Glossary” for further definition.
- For a heat pump system.“Glossary” for further definition
Wiring (Conventional System)
Wire the thermostat to your conventional system. a Starting with the C Wire, match the sticky tag on the wire to the terminal labels.
You must have a C wire. Straighten wire and gently slide into terminal hole until it clicks into place. (If you need to remove a wire, use a pen tip to press the terminal release and then pull wire out.)
Note: Refer to the wiring picture you took in Step 2.
Tip: To make it easier to slide the wire into place, use a pen tip to hold down the terminal release.
Note: The wiring for your application might be different than the wiring shown below.

Wiring (Conventional System continued)
- c In the image on the right, check the box next to each connection. You will use this checklist in Step 9.
- d Verify wire is firmly secured by gently pulling on wire.
- e Repeat steps a–d for all other wires.
- f Push any excess wire back into the wall opening after all wires are installed.
Important!
Check the box for each wire you connect. You will need this information in Step 9.
Wiring (Heat Pump System)
Wire thermostat to your heat pump.
- Starting with the C Wire, match the sticky tag on the wire to the terminal labels.
- Slide wire gently into terminal hole until it clicks into place. (If you need to remove a wire, use a pen tip to press the terminal release and then pull the wire out.)
Note: The wiring for your application might be different than the wiring shown below.

- d Verify wire is firmly secured by gently pulling on wire.
- e Repeat steps a–d for all other wires.
Note: If old thermostat has separate wires on AUX and E, use a wire nut to attach both wires to a separate wire. Slide this third wire into the W2-Aux/E terminal. - f Push any excess wire back into the wall opening after all wires are installed.
Alternate wiring (Conventional System)
Use this if your wire labels don’t match the terminal labels.
Note: You must have a C wire or equivalent.
Alternate wiring key (Conventional System)
- If you have both an R and Rc wire, unplug the jumper loop by pulling on the wire loop.
- If your old thermostat had both R and RH wires, connect the R wire to the Rc terminal, the RH wire to the R terminal, and unplug the jumper loop.

- If your old thermostat had both R and RH wires, connect the R wire to the Rc terminal, the RH wire to the R terminal, and unplug the jumper loop.
- If your old thermostat had both V and VR wires, check honeywellhome.com/wifi-thermostat for help.
- If your old thermostat had separate O and B wires, and is controlling a single zone heat pump system, attach the B wire to the C.
- If there is more than one thermostat controlling the system, call Resideo zoning at 800-828-8367 for wiring assistance.
- If your old thermostat had separate Y1, W1, and W2 wires, check honeywellhome.com/wifi-thermostat for help.
- If the old thermostat has separate wires on Aux and E, use a wire nut to attach both wires to a separate wire. Slide this third wire into the W2-Aux/E terminal.
- This is the system monitor. If the monitor finds a problem, you will see an orange alert button on the thermostat home screen.
Attach thermostat to wallplate. Align the thermostat with the wallplate and then snap into place.
Switch heating/cooling system ON. Important!
- 8a Verify that the C wire is connected at the thermostat and at the heating/cooling system.
- 8b Make sure the heating/cooling system door is firmly secured.
- 8c Switch power back ON for your heating/cooling system at the breaker box or its power switch.
Before connecting to your Wi-Fi network,
you need to set initial thermostat options

Honeywell WIFI Smart Color Touchscreen Programmable Thermostat-FAQs
How does the Honeywell Smart Thermostat work?
The thermostat uses Smart Response Technology to learn your schedule and automatically adjust heating and cooling times to match your preferences. It also sends alerts for filter changes and extreme temperature warnings.
What does the MODE button do on the Honeywell thermostat?
The MODE button allows you to cycle through different system settings like heat, cool, auto, or off. Stop at your desired mode, and it will activate automatically.
How do I connect the Honeywell thermostat to WiFi?
Tap the Menu button on your thermostat, select the WiFi option, choose your network from the list, and enter your password. A success message will confirm the connection.
How is the smart thermostat powered?
Most smart thermostats, including Honeywell’s, require constant power supplied by a C-wire (common wire) from your HVAC system. Older systems may not have this wire.
What is the fan mode on the thermostat for?
Fan mode circulates air throughout your home, helping to balance temperatures and eliminate hot or cold spots—especially useful in rooms that don’t stay comfortable.
What components are inside a thermostat?
Thermostats contain sensors to detect temperature changes. Mechanical models use bimetallic strips, while smart models rely on electronic sensors for more accurate control.
How can I manually adjust the temperature?
Use the “+” and “–” buttons to set your preferred temperature. Press “Hold” to maintain that setting until you change it again manually.
Is the Honeywell thermostat WiFi-enabled?
Yes, it connects to your home WiFi, allowing remote control through the Honeywell Total Connect Comfort app on your smartphone or tablet.
