Customer Question

I have an old bryant thermostat (80s) on a heatpump that I want to change. The wiring on the old one is as follows: Red-r, blue-C, Green-G, Yellow-y, White-w1, Brown-e, black-w2, orange-0.
I am replacing it with a honewell rth6350. It is marked with L, AUX/E, G, O/B, Not Used, Y, R, RC. In the wiring diagram, it shows E going to AUX. It also shows W or w2 going to aux. Y Goes to y, R goes to RC, O goes to O/B, and it says to leave C disconnected. I'm really not sure what to do about the w1 & w2

Please give me time to respond as typing, researching and adding links takes me time to do so please be patient and often I will ask you questions to narrow down the issue so do not rate me until we are done thanks.

That really is not the right thermostat for your setup you have 2 stage heating with emergency heat, that thermostat is not capable of doing that.
