Tools you will need:
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.
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.
3 Remove the old thermostat’s faceplate
On most thermostats, you can take off the faceplate by grasping and gently pulling or popping it off. Some thermostats may have screws, buttons, or clasps.
Do not remove any wires from your thermostat
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 Lyric thermostat will not work. If you are unsure visit
5 Take a picture of the old wiring
Be sure to include the letters next to the terminals where the wires are inserted. This will be a helpful reference when wiring your Lyric thermostat.
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. The Lyric thermostat does not need jumpers
7 Record if you have wires in the following terminals
Do not include jumpers as part of your count.
Check all that apply:
| Terminal | Color of wire |

8 Record the existing wire configuration
Note the color of the wires that are plugged into your old thermostat’s terminals. You will need this information to correctly wire your Lyric thermostat.
If the wires are in terminals that are not listed, you will need additional wiring support. Visit lyric.honeywell.com/support/installation to find out if the Lyric thermostat will work for you.
9 Disconnect the wires and remove old wall plate
Use a screwdriver or a ballpoint pen to release wires from terminals.
Wrap the wires around your ballpoint pen to prevent them from falling back into the wall.
10 Insert the recommended wall anchors
It is recommended that you use the provided anchors when mounting your thermostat.
You can use the wall plate to mark where you want to place the wall anchors. Drill bit size 7/32”
11 Check for any paint gaps or screw holes left by the old thermostat
If you choose to use the optional wall cover to hide these blemishes, snap the wall plate to the optional wall cover before screwing to the wall.
12 Bundle and insert wires through the clear rubber holder
Guide the wires through the clear rubber holder on the back of the wall plate. Make sure at least 1/4-inch of each wire is exposed for easy insertion into the wire terminals.
13 Review your answer from Step 7
Set the R-switch up or down based on your answer from Step 7
14 Firmly connect remaining wires from Step 8
Push each remaining wire into its corresponding terminal (one wire per terminal) until it is firmly in place. If you misplace a wire, use a ballpoint pen to push down on the terminals and release the wire. Gently tug on wires to verify they are secure.
15 Use the provided screws to mount the wall plate
Make sure the wall plate is even by keeping the bubble in the level between the two lines
