What Is in the box

TOOLS NEEDED

Guide 1 or Guide 2? Start here to find out.
The steps in this section will help you decide which install guide you’ll use to complete the installation.

STEP 1
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.

STEP 2
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.

STEP 3
Remove your old thermostat cover from the wall.

Does your old thermostat’s backplate have any of these indicators?

STEP 4
Take a picture of the wires connected to the terminals of your old thermostat. You may need to reference this photo later on.

Do you have a C wire connected to your old thermostat?

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.

Have you completed steps 1 – 4 in the ‘Start Your Install’ section?

STEP 5
Carefully disconnect and label the wires from your old thermostat one at a time, using the labels provided.STEP 6
Unscrew the mounting plate of your old thermostat to remove it from the wall.

STEP 7
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.

STEP 8: OPTIONAL
If using the trim plate, align the mounting holes on the trim plate and backplate and press them into place together

STEP 9
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.

Do you have more than one R wire? (That includes R, Rc, and Rh)

STEP 10
Insert your remaining wires into the side (not the front) of their corresponding terminal blocks

STEP 11
Tug on the wires gently to ensure they are securely connected.

STEP 12
Carefully push any excess wire back into the hole and ensure there are no drafts coming from the hole(s) in the wall.

STEP 13
Gently press your ecobee thermostat into the backplate until it ‘clicks’ into place

STEP 14
Turn the power to your HVAC system back on using the master switch or at the circuit breaker box.

STEP 15
Say hi to your new ecobee! The screen will power on and guide you through the set-up and registration.

Congratulations, you did it!
To complete your set-up, follow the instructions on your ecobee screen.

Install your ecobee without a C wire

Take a picture of the wires connected to your control board. You may need to reference this photo later on.

STEP 8
Label only the R, Y or Y1, G and W or W1 wires with the matching labels provided. If you have more than one wire going into these terminals, only label those coming from your thermostat.

STEP 9
Disconnect the labeled R, Y, G and W wires from the control board.

STEP 10
Connect the wires you disconnected from the control board into their matching gray terminal blocks on the Power Extender Kit.

STEP 11
Tug on the wires gently to ensure they are securely connected.

STEP 12
Connect the 5 white wires coming out of the Power Extender Kit to the corresponding terminals on your control board.Check that you have installed the Power Extender Kit correctly. It should be installed between your thermostat wiring and your control board.

TROUBLESHOOTING

If your ecobee doesn’t turn on, please try these steps

Check that all wires are properly inserted into the terminal blocks at the thermostat. Tug on the wires to ensure they are not loose.
Make sure your HVAC cover panel is closed. Some systems will not turn on if the cover panel has not been closed properly.
If you have only one R wire (either R, Rc, or Rh), make sure it’s inserted into the Rc terminal.
