⚠️ Step 1: Turn Off Power to Your HVAC
Before removing your old thermostat, shut off the power to your heating and cooling system at the breaker panel. This ensures your safety and protects your HVAC system from electrical damage.
🛠️ Tip: Test that the system is off by changing the temperature setting on your old thermostat and ensuring nothing turns on.
🔧 Step 2: Remove the Old Thermostat
- Remove the thermostat faceplate.
- Label each wire according to the terminal it’s connected to (e.g., Y, G, W, Rc, C).
- Disconnect the wires and remove the old baseplate.
- Use the Ecobee trim plate if your wall has old holes or doesn’t look clean.
📍 Step 3: Install the Ecobee Mounting Plate
- Feed the labeled wires through the center of the mounting plate.
- Use the built-in level to ensure it’s straight.
- Screw it into the wall using the provided screws.
If you don’t have a C wire, don’t worry — Ecobee includes a Power Extender Kit (PEK), and we’ll cover how to use it in the next step.
⚡ Step 4: Connect the Wiring
If you have a C wire:
- Match each wire to the appropriate terminal on the thermostat base (e.g., W1, Rc, G, Y1, C).
If you don’t have a C wire:
- Use the included Power Extender Kit (PEK).
- Mount the PEK at your furnace and connect wires as per the included instructions.
- This allows your thermostat to receive constant power without a C wire.

💡 Step 5: Attach the Thermostat Display
Once the base is wired, gently push the Ecobee display onto the base until it clicks. It should power on automatically if the wiring is correct and power has been restored.
If it doesn’t power up, double-check the breaker, and ensure all wires are secure.
📲 Step 6: Download the Ecobee App and Create an Account
Download the Ecobee app from the App Store or Google Play. Create an account or log in.
Then:
- Tap “+ Add a Device”
- Select “Thermostat”

📶 Step 7: Connect to Wi-Fi and Register
When prompted:
- Choose your Wi-Fi network
- Enter the password
- Wait for connection confirmation
- Register the device using your Ecobee account
This allows your thermostat to download updates, access weather forecasts, and sync with smart home platforms like Alexa, Siri, Google Assistant, SmartThings, and Apple HomeKit.
🗓️ Step 8: Set Your Schedule
In the app or on the thermostat:
- Navigate to Settings > Schedule and Preferences
- Set your preferred temperature for:
- Home
- Away
- Sleep
You can also enable Smart Home/Away, which automatically adjusts the temperature when it senses you’re not home — saving you money on your energy bill.
🧭 Step 9: Install and Pair the SmartSensor
The included SmartSensor helps regulate temperature in rooms that tend to run hot or cold. To set it up:
- Pull the battery tab to power the sensor.
