Install your thermostat
Switch OFF power to your heating/cooling system
1.1a Important! To protect your equipment, switch OFF the power to your
heating/ the cooling system at the breaker box or the system switch.
1.1b Confirm power is OFF.
Try to turn on heating/ cooling equipment by changing the temperature on your
old thermostat.
Your power is OFF if your system does not turn ON.
This thermostat works with common 24 volt systems such as forced air, hydronic, heat pump, oil, gas, and electricity. It will not work with millivolt systems, such as a gas fireplace, or with 120/240 volt systems such as baseboard electric heat.
Remove old thermostat faceplate and leave wires connected
1.2a Take a picture of the wire connections for later reference.
1.2b 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/support 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.
If you have an older thermostat with a sealed mercury tube, see the warning page for proper disposal instructions.
Label wires
Do NOT label by wire color.
Use the supplied sticky tags to label each wire as you disconnect it. Label
wires according to old thermostat terminal designations, not by wire color.
Tip: If no tag matches a terminal designation, write the appropriate
letter on a blank sticky tag.
Tip: Wrap the wires around a pencil to prevent them from falling back
into the wall.
Remove old wallplate
Remove the old wall plate from the wall after all wires are labeled and disconnected.
Mount new wallplate for Wi-Fi 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 : You may be able to use your existing wall anchors. Hold the wallplate up to the existing anchors to check for alignment.
Connect wires
Important! C wire is required and is the power source. Without a C wire, your
thermostat will not power up.

1.6a Starting with the C Wire, match the sticky tag on the wire to the
terminal labels.
1.6b Straighten wire and gently slide into the terminal hole until it snaps
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: Refer to the wiring picture you took in Step 1.2.
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.
Labels don’t match or have a heat pump system? See User Guide.
1.6c In the image on the right, check the box next to each connection. You

1.6e Repeat steps a–d for all other wires.
1.6f 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 1.9.
Note: The L terminal on the lower right is used only for Heat Pump systems.
Note: If the old Heat Pump thermostat had separate wires on Aux and E, connect
the Aux and E wires and one end of a new piece of wire using a wire nut (not
included). Then slide the other end of the new wire into the W2-Aux/E
terminal.
