Remove Old Thermostat
1.Turn Off the Power
or
To ensure the power to your heating and cooling system has been turned off, try to turn on heating or cooling by changing the
temperature on your old thermostat
2. Remove the old thermostat cover
Remove the old thermostat’s front cover from the wall base. Some covers pull off easily, while others may need to be
removed by prying the cover off with a screwdriver.
3. Label wires
Using your screwdriver, carefully unscrew one wire at a time from the terminal block and attach the corresponding wire label
sticker.
Please note that not all terminals may be used, and that there’s no standard color code for thermostat wires, so your wire
colors may vary.
For your reference, we’ve included a terminal label reference chart as below to help you connect the wires in your old
thermostat to your new thermostat in case you get stuck.
