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.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 4

TIP:
Look for your master switch or circuit breaker box in the basement, attic, utility closet, or behind a wall panel near the thermostat.

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.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 5

TIP:
If you have a boiler, check to see that the main flame is extinguished.

Remove your old thermostat cover from the wall.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 6

TIP:
Many thermostats simply pop off or unclip from the base, while others may have screws that you will need to remove.

Take a picture of the wires connected to the terminals of your old thermostat. You may need to reference this photo later on.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 8

WARNING:
ecobee3 lite is designed for 24VAC with a 2A maximum current. Do not connect it to line (high) voltage or millivolt systems.

Install your ecobee

with a C-wire

If you have a C wire, it will power your ecobee. You won’t need the Power Extender Kit included in the box.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 10

Carefully disconnect and label the wires from your old thermostat one at a time, using the labels provided.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 12

TIP:
If you have a jumper between Rc, Rh, or R, leave it alone. Only label the wires that run from your wall into a terminal block.

Unscrew the mounting plate of your old thermostat to remove it from the wall.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 13

WARNING:
Be careful, as some thermostats may contain mercury. Recycle your old thermostat safely with your local hazardous waste facility.

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.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 14

OPTIONAL

If using the trim plate, align the mounting holes on the trim plate and backplate and press them into place together.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 15

Pull the wires through the hole in the middle of the backplate and then attach the backplate to the wall using the drywall anchors and screws provided.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 16

TIP:
Use a 3/16” drill bit to drill a hole for the drywall plugs.

Insert your remaining wires into the side (not the front) of their corresponding terminal blocks.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 18

TIP:
Press the terminal block levers to insert the wires more easily.

Tug on the wires gently to ensure they are securely connected.

Carefully push any excess wire back into the hole and ensure no drafts are coming from the hole(s) in the wall.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 20

TIP:
Large holes behind your thermostat will affect temperature readings. Prevent drafts by covering the hole(s).

Gently press your Ecobee thermostat into the backplate until it ‘clicks’ into place.

Ecobee3 Lite Wi-Fi Enabled Smart Thermostat 21

TIP:
If the thermostat ‘rocks’ or is not flush with the wall, be sure the excess wires are pushed into the wall.

Turn the power to your HVAC system back on using the master switch or at the circuit breaker box.
