Title: Wi-Fi thermostat
Post by: speedbugy on July 13, 2015, 09:31:20 PM
I have a Trane unit with a TCONT802AS32DAA thermostat. I am wanting to install a RTH8580WF thermostat. My old one does not have a C wire, but does have a B wire that hopefully will supply the 24 volts if the instructions are right. The unit is a package heat & a/c. Attached is a picture of my current thermostat and if I can post 2, the new thermostat wall plate. Most of he wires match up, but the ones on the left side do not. Any help would be appreciated.

Thanks !

To give a update, I didn't need a professional to install it. I call Honeywell on their help line and they were very helpful. I did have to get a bit more expensive thermostat Model RTH9580WF. My 24 volt wire was there, it was labeled B on my old thermostat. Works like a champ.
