I am having issued getting my thermostat working. I went to the compatibility checker and entered the following wires
the checker indicates it is compatible, but when I try to install it, there in no X2 wire to select in the the app.?? My system is a Carrier FAANF036. The thermostat I am replacing is a Weathertron with 8 wires. Any advice would be greatly appreciated.
Thank you in advance
