1. Install your thermostat
1.1 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.
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 electric. It will not work with millivolt systems, such as a gas fireplace, or with 120/240-volt systems such as baseboard electric heat.
1.2 Remove old thermostat faceplate and leave wires connected
Take a picture of the wire connections for later reference.
If no wire is connected to a terminal labeled C or no C terminal exists on the old thermostat, call 1-800-468-1502 for wiring assistance.
Important!
C wire is required and is the primary power source for your thermostat. Without a C wire, your thermostat will not power up.
If you have an older thermostat with a sealed mercury tube, see warning page for proper disposal instructions.

1.3 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.
Note: If no tag matches a terminal designation, write the appropriate letter on a blank sticky tag.
1.4 Remove wallplate
Remove the old wallplate from the wall after all wires are labeled and disconnected.
1.5 Separate Z-Wave thermostat and its wallplate
On your new thermostat, grasp the finger holds on the top and bottom of the wallplate with one hand and the thermostat (front) with the other hand. Pull pieces apart.
Illustration showing how to separate the thermostat from its wallplate by pulling them apart.
1.6 Mount wallplate for Z-Wave 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.
Illustration of the wallplate showing mounting holes and indicating where screws and anchors are used.
1.7 Connect wires
Starting with the C Wire, match the sticky tag on the wire to the terminal labels.
Important!
C wire is required and is the primary power source. Without a C wire, your thermostat will not power up.
Loosen screw, insert wire on inside edge of terminal, then tighten screw. Verify wire is firmly secured by gently pulling on wire. Repeat for all other wires. Push any excess wire back into the wall opening after all wires are installed.
Remove metal jumper only if you have both R and RC wires.
Note: The wiring for your application might be different than the wiring shown.
Labels don't match or have a heat pump system? See User Guide.
1.8 Remove battery tab
The thermostat is shipped from the factory with the coin cell installed. To keep the battery from discharging during shipment and storage, a plastic tab is inserted in the battery holder. Simply pull the plastic tab out of the battery tray. Make sure that the battery tray is fully inserted into the thermostat.

1.9 Attach thermostat to wallplate
Align the thermostat onto the wallplate and snap into place.
1.10 Switch heating/cooling system ON
Important!
- Verify that the C wire is connected at the thermostat and at the heating/cooling system.
- Make sure the heating/cooling system door is firmly secured.
- Switch power back ON for your heating/cooling system at the breaker box or its power switch.

1.11 Set date and time
Use the `[change]` buttons (or `[up arrow]` / `[down arrow]`) to change the displayed time and date. Press and hold an arrow to quickly change a setting. Press DONE to save changes.

1.12 Determine your heating/cooling system type
Important!
Heating/cooling system type must be set so that your thermostat operates properly and does not damage your system.
If you have a traditional system (single stage heating and cooling), your thermostat is set up by default to control this system. However, you will still need to connect your thermostat to a Z-Wave network. To do this, enter system setup (see step 2.1) and then proceed to Step 3.
If you DO NOT have a single stage heating and cooling system, you MUST change the system type by setting system function 0170. See page 40 in the User Guide for a list of options. Go to Step 2.
Not sure of your heating/cooling system type? Visit yourhome.honeywell.com or call Honeywell Customer Care toll-free at 1-800-468-1502.
2. Setup your thermostat
