A:AnswerBest buy uses a 3rd party for these installations, ecobee comes with both options, if you have a c wire or need to go through the c wire bypass, it comes with extra wiring for that.
A:AnswerLet's take a closer look at that together. Please send a photo of your wiring to support@ecobee.com or use our handy online compatibility checker. https://www.ecobee.com/compatibility/
A:AnswerI have a 2300SF ranch with one AC zone. I have set the second sensor in the Master bedroom which is at the opposite side of the house from thermostat. The Master bedroom tended to run about three / four degrees warmer than the rest of the house. With the addition of the sensor, when the sensor recognizes the Master is occupied, the thermostat seems to engage based on the average of the two thermostats. In my situation it appears the sensor did exactly as advertised and the Master is now more comfortable.
A:AnswerThe setup walk-through looked pretty easy. I do not have a dual zone but looking through on screen instructions, it was step by step. And their documentation was easy to follow.
A:AnswerYes. It comes with the adapter in the box. I didn’t need it. Great thermostat. Besides Alexa and the other fun stuff, very few thermostats allow you to set the temperature swing, control accessories (humidifier, HRV) or set other functions and limits like the Ecobee.
