I have a new luxaire heat pump with aux heat. I am replacing the tstat. Is the supposed to be a wire for the aux slot? I have the red on the r/rc, the blue on the c, the yellow on the y, the green on the g and the white & orange together on the o/b. any ideas are welome.
Thanks

Brand and model number of the old thermostat?
Brand and model number of new thermostat?

When you took the wires off the old thermostat how were they wired. What color to what terminal? (I am sure you wrote this VERY IMPORTANT item down.)

As I said in my original post, I have a brand new luxaire heat pump with a/c & aux heat. These are new wires for the system. I just don't know which wire, if any, is supposed to go to the aux. seems there should be one that does.
Thanks

Sorry but I still need this info

Model number of the new system for the inside unit ?

Without these numbers I cannot help.
