Ecobee Smart Thermostat Voice Installation Guide
Important Information
Look out for these icons at the bottom of each step. They indicate useful tips and important reminders.
First things first. Here’s what you’ll find in the box:
You may also need these tools:
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.
TIP: Look for your master switch or circuit breaker box in the basement, attic, utility closet, or behind a wall panel near the thermostat.
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.
TIP: If you have a boiler, check to see that the main flame is extinguished.
STEP 3
Remove your old thermostat cover from the wall.
TIP: Many thermostats simply pop off or unclip from the base, while others may have screws that you will need to remove.
CHECKPOINT: COMPATIBILITY
CHECKPOINT: COMPATIBILITYDoes 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.
WARNING: ecobee is designed for 24VAC with a 2A maximum current. Do not connect it to line (high) voltage or millivolt systems.
CHECKPOINT: C WIRE
Do you have a C wire connected to your old thermostat?
TIP: The wiring on your old thermostat may look different— just check to see if there’s a C wire.
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 (PEK) included in the box.
TIP: To install accessories (humidifier, dehumidifier or ventilator) please refer to the wiring diagrams at ecobee.com/wiring.
STEP 5
Carefully disconnect and label the wires from your old thermostat one at a time, using the labels provided.
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.
STEP 6
Unscrew the mounting plate of your old thermostat to remove it from the wall.
WARNING: Be careful, as some thermostats may contain mercury. Recycle your old thermostat safely with your local hazardous waste facility.
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. If using the trim plate, align the mounting holes on the trim plate and backplate and press them into place together.
STEP 8
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.
TIP: Use a 3/16″ drill bit to drill a hole for the drywall anchors.
CHECKPOINT: INSERT YOUR R WIRE(S)
Do you have more than one R wire? (That includes R, RC, and RH)
STEP 9
Insert your remaining wires into the side (not the front) of their corresponding terminal blocks.
TIP: Press the terminal block levers to insert the wires more easily.
STEP 10
Tug on the wires gently to ensure they are securely connected.
TIP: When a wire has been connected correctly, the lever on that block will lower.
STEP 1 1
Carefully push any excess wires back into the hole and ensure there are no drafts coming from the hole(s) in the wall.
TIP: Large holes behind your thermostat will affect temperature readings. Prevent drafts b 19 y covering the hole(s).
STEP 12
Gently press your ecobee into the backplate until it ‘clicks’ into place.
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.
STEP 13
Turn the power to your HVAC system back on using the master switch or at the circuit breaker box.
Congratulations, you did it!
Say hi to your new ecobee! To complete your setup and registrations, follow the instructions on your ecobee screen.
TIP: If your thermostat does not power on, please see the troubleshooting section on PAGE 48.

Install your ecobee without a C wire
If you don’t have a C wire, you’ll need to use the Power Extender Kit (PEK) included to reliably power your ecobee.
CHECKPOINT: 3 OR 4 WIRES
The Power Extender Kit requires your system to have either of the following: 4 wires W/W1, Y/Y1, G, and R (or RC or RH) or 3 wires Y/Y1, G, and R (or RC or RH) Do you have these wires?
STEP 5
Take your Power Extender Kit, wire labels, tools, your smartphone, and go to your HVAC system.
TIP: Your HVAC system can most often be found in your basement or your attic.
STEP 6
Open your HVAC system’s cover to reveal the control board.
WARNING: HVAC systems contain high voltage wires. Use caution when working with the control board. If you’d rather leave it up to a professional, we can help you find one quickly. Visit ecobee.com/proinstall.
STEP 7
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 going to your thermostat.
