If wires are not automatically detected during the guided setup, how can I configure the wires manually?


This article applies to all ecobee thermostats except Smart, Smart SI, EMS and EMS SI.

If your ecobee thermostat hasn’t detected the wiring correctly during the guided setup, you can manually configure the correct wiring.

During the guided setup, there will be a screen displaying the wires your ecobee has detected. These wires will be highlighted in white.

It will ask you whether this information is correct.

If there is an error select No.

You can:

  1. Remove your ecobee from the wall to adjust the wiring.

    Warning: Before you adjust wiring, ensure that your system is powered off. If your HVAC equipment doesn't have a master switch, go to your circuit breaker box and turn off the breaker.

    ecobee thermostats require a constant 24VAC power supply from your HVAC system to operate. You may verify that your equipment is off by confirming that your ecobee is powered off.


  2. If you are positive that the wires are connected to the correct terminals on your ecobee backplate, manually configure the missing wires in guided setup.

    To do so, tap the wire terminal that has an undetected wire. It will turn white. Select Continue, then follow the remaining steps to complete setup.


If you notice a wiring error after you've completed setup... 

On your ecobee thermostat, tap MENU and select SETTINGS. Select EQUIPMENT, then WIRING to see which wires your thermostat has detected.

If you notice an error, tap BACK, then select RE-CONFIGURE EQUIPMENT and follow the guided set up to re-configure your ecobee and manually configure the wiring.
