Opening the Ecobee4 box reveals everything needed for a smooth install:
Thermostat wiring varies by home age, location, and HVAC type. Start by popping off the cover of your current thermostat and snapping a photo of the wires.
Then, use Ecobee's compatibility checker to input your wiring—95% of systems are compatible.
Download the Ecobee app (iOS/Android) beforehand for guided videos and tips.
First, power off your HVAC at the breaker. Back at the thermostat, address the C-wire (common wire) for constant power—essential for Alexa, HomeKit, and the always-on display (unlike some competitors like Nest).
Check if your system has a C-wire labeled 'C'. If not, repurpose an unused wire or use the included Power Extender Kit at your HVAC unit. Basic DIY skills suffice, but pros help for tricky spots.
Disconnect wires (label them with provided stickers), mount the new backplate (use trim plate for old holes), reconnect wires firmly, tuck slack into the wall, and power on. The screen awakens for setup.
The thermostat auto-detects wires—confirm them. Note accessories like humidifiers. Specify furnace or boiler if applicable.
Name your thermostat for voice control. Connect to Wi-Fi via app or screen. Set HVAC mode (heat/cool/auto), preferred temps, and Smart Home/Away. Enter location/timezone, then use the 3-character code in the app to register and create an account.
Stand near the thermostat, power on the sensor by pulling the tab—it appears automatically. Name it (more available as 2-packs).
