First things first.
STEP 1 STEP 2 Power off your Heating, Ventilation, and Air Conditioning (HVAC) system by using the master switch or circuit breaker box. This is important for your safety. Confirm your system is off by turning on your heat (during winter) or your AC (during summer). Wait a few minutes— you should not feel air coming from your vents. ON OFF ON 5 OFF TIP: Look for your master switch or circuit breaker box in the basement, attic, utility closet, or behind a wall panel near the thermostat.

Rc 1 W/W Y/Y1 RC RH 11 TIP: To install accessories (humidifier, dehumidifier or ventilator) please refer to the wiring diagrams at ecobee.com/wiring TIP: If you have a jumper between RC , R H , or R, leave it alone.
STEP 6 STEP 7 Unscrew the mounting plate of your old thermostat to remove it from the wall. Decide if you want to use the trim plate with your ecobee. The trim plate is useful if you want to hide marks or holes left on the wall by your old thermostat. If using the trim plate, align the mounting holes on the trim plate and backplate and press them into place together.

Gently press your ecobee into the backplate until it ‘clicks’ into place. TIP: Large holes behind your thermostat will affect temperature readings. Prevent drafts by covering the hole(s). TIP: If the thermostat ‘rocks’ or is not flush with the wall, be sure the excess wires are pushed all the way into the wall.
