5. Pull the end of each wire out of the terminal.
6. Unscrew and remove the base plate from the wall.
7. Screw the base plate of the new smart thermostat to the wall. Be sure the base plate is level.

9. Snap the smart thermostat onto the base plate.
10. Turn on the service switch at the furnace.
11. At the thermostat, follow the touch-screen prompts to choose the preferred language and internet setting, which allows you to control the thermostat remotely from a tablet or smart phone.
12. Next, enter the year when house was last remodeled, then select a name for the thermostat.[
13. Select the lowest and highest room temperatures for when you're not at home.
