Removing your old thermostat

Turn power OFF.

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

Fig 1 Turn power OFF

2. Check that your system is off.
Change the temperature on your old thermostat to be above room temperature in heat mode or below it in cool mode. 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.

3. Remove the old thermostat’s faceplate.
On most thermostats, you can take off the faceplate by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps.

Caution: Do not remove any wires from your thermostat at this time!

Fig 3 Remove the old thermostat’s faceplate

4. Make sure there are no 120/240V wires.

Caution:

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.

Fig 4 Make sure there are no 120 or 240V wires

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 new 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.

Fig 5 Take a picture of how your wiring looks right
now

6. Record which R-wire(s) you have and write down the color of the wire(s).

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

$Fig 6 Record which R-wire$s$$

7. Record the remaining wires and 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):
