I'm going to the honeywell which has Rh, Rc, W, Y, G. Any Help would be awesome!! Thanks

The Honeywell RTH230B will not support your multistage heatpump.
I recommend a Honeywell RTH7400 or RTH7500, with autochangeover.

(Sub your brown for black)

Set option 170 to 7. Option 190 = 0. Option 240 = 9.

"Tip of the Day" Remember to remove power first.
