Honeywell asks you to connect to Rh, Rc, W, Y, G. The existing Bryant thermostat uses R, G, Y1, W1 and blue wire to C. The Honeywell online wizard doesn't recognize this model however it seems like I may want to connect a jumper from Rh to Rc and then connect R to either Rh or Rc, W1 to W, Y1 to Y, G to G and don't connect C to anything. Is that correct?

I had a similar issue with my Bryant. Hooked up all 5 wires from old tstat to Honeywell and heat worked but not AC. Could not find any real good solutions online so I called customer support.

W to W, Y to Y, G to G, R to Rh and have the supplied jumper from Rh to Rc installed. Do not connect blue wire (C terminal on Bryant thermostat) to anything.

Worked for me! Hope it helps.
