ecobee

My old thermostat has S1/S2 wires. Where do these go on the ecobee?

 

S1/S2 terminals are for an outdoor temperature sensor. This type of sensor is not supported with ecobee—we obtain weather data over Wi-Fi, and this weather data is based on the location details you entered upon registering your ecobee.

If your old thermostat has S1/S2 wires, you can tape them off and tuck them away as they are not needed.
