How to Complete an Ecobee Smart Thermostat Install in 6 Easy Steps

Installing a smart thermostat, like the ecobee, is a simple way to take control of your home’s heating and cooling. It’s a straightforward process that involves shutting off the power, removing the old thermostat, connecting the wires to the new ecobee thermostat, and following the setup instructions on the device or app.

Step by Step Tutorial: Ecobee Smart Thermostat Install

Before diving into the installation, it’s essential to understand that you’ll be working with your home’s electrical system. The steps below will guide you through the process safely and efficiently.

Step 1: Turn Off the Power

Turn off the power to your thermostat at the circuit breaker.

It’s crucial to ensure that there is no electrical current flowing to your thermostat to avoid any risk of electric shock.

Step 2: Remove the Old Thermostat

Carefully remove the old thermostat cover and unscrew it from the wall.

Take a picture of the wiring before you disconnect anything. This will serve as a reference when wiring the ecobee.

Step 3: Install the ecobee Backplate

Position the ecobee backplate on the wall and mark the screw holes for drilling.

Use the included screws and drywall plugs to secure the backplate to the wall.

Step 4: Connect the Wires

Refer to the picture you took and connect the wires to the corresponding terminals on the ecobee backplate.

If you have an extra C wire, great! If not, you’ll need to use the Power Extender Kit (PEK) included with your ecobee.

Step 5: Attach the ecobee Thermostat

Snap the ecobee thermostat onto the backplate.

Make sure it clicks into place and is secure on the wall.

Step 6: Turn the Power Back On

Turn the power back on at the circuit breaker.

Watch the ecobee come to life and proceed with the on-screen setup instructions.

After completing the installation, your ecobee smart thermostat will display a welcome screen, and you can follow the on-screen prompts to set up your preferences, connect to Wi-Fi, and pair it with your phone for remote access.

  • Label your wires as you disconnect them from the old thermostat to avoid confusion.
