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. These icons indicate useful tips and important reminders.
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. ON OFF OR ON 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.
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. OR TIP: Many thermostats simply pop off or unclip from the base, while others may have screws that you will need to remove.
CH E C KP O I N T: CO MPAT I B I L IT Y Does your old thermostat’s backplate have any of these indicators? WARNING HIGH VOLTAGE 110 VAC OR 120 VAC OR 240 VAC L1 L2 YES NO Sadly, you might not be compatible You can double check here: ecobee.
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: ecobee3 lite is designed for 24VAC with a 2A maximum current. Do not connect it to line (high) voltage or millivolt systems.

STEP 5 Carefully disconnect and label the wires from your old thermostat one at a time, using the labels provided. Rc 1 W/W Y/Y1 RC RH 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. 1 W/W RC Y/Y1 RC RH 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.
ST E P 8 : O PT I O N AL If using the trim plate, align the mounting holes on the trim plate and backplate and press them into place together.
STEP 9 Y Y/ 1 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. W/W1 G Rc C TIP: Use a 3/16” drill bit to drill a hole for the drywall plugs.

STEP 1 1 Tug on the wires gently to ensure they are securely connected. RH C W 1 W 2 PE K TIP: When a wire has been connected correctly, the lever on that block will lower.
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. TIP: Large holes behind your thermostat will affect temperature readings. Prevent drafts by covering the hole(s).
STEP 1 3 W/W1 Y1 G Rc Gently press your ecobee thermostat into the backplate until it ‘clicks’ into place. C 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 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. hi TIP: If your thermostat does not power on, please see the troubleshooting tips in the ‘Extras’ section.
ALL D O N E! Congratulations, you did it! To complete your set-up, follow the instructions on your ecobee screen.
G UIDE 2 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.
