I did not. the installation guide said to place a jump between y&w if using a heat pump without backup and so I did that. My house wiring has only an R. thermostat has a pre-existing jump between R & R C, which I left in place when i attached the R wire. I do not have an RH house wire.
I realized that I should clarify. There is a jump between R&RC, and I left that in place, so there are two jumps on this thermostat;one that was already in place between R&RC and one that I put in between Y & W.
Thank you. Asking again.... You said ". If you can't or don't want to determine if the blue wire is hooked up to B on your Trane air handler..."
How can I tell if the blue wire is hooked up in that way? (I do have a blue wire coming out of the house wiring. Is that it?)
I just started my upgraded week and so am asking again now, how can I tell if the blue wire is attached to the trane air handler? do you mean if a blue wire comes out of the house wiring?... if that's not what you mean, is there someplace on the unit itself I should look for blue wiring? Am I getting out of something that I could try myself? (I'm bold but I'm not foolish. ;)
