I have a Trane older type (2006) Comfortlink II thermostat

Customer Question

I have a Trane older type (2006) Comfortlink II thermostat with three wires, D, R, B. I want to change to a new wifi thermostat. Most say that a Nest won't work, because of the Data (D) wire. Other than the Trane 950XL thermostat, are there any other WiFi thermostats that can use the 3-wire setup? Honeywell? Lyric?

Unfortunately no you would need to use the Tran 950XL Trane does this for a reason so you have to buy their product. It is a great thermostat though just pricey.
