Question about Hunter Fan Company 5/1/1 Programmable Thermostat
This should help you. You need to know if your thermostat is powered by the unit or independently and which way your reversing valve switches (I,m not sure on a Bryant, but probably Your old O wire goes to your new O terminal. They should pretty much match up, the new stat just has more options. Thermostat wiring

I hate to tell you this but that thermostat will not work with your system.
The system you have is a 2 stage system and the thermostat you got will only do one stage.
You will need to get a thermostat theat is compatible with stage heating and cooling.
The W1 is the first stage heating, the W2 is second heating. The same is true for Y1 and Y2 on cooling
You could double them up, but it would defeat the encomoy reasons for having a 2 stage unit.
Wish I could give you better news..
I hope that this will help you to solve your problem!
Thanks for using Fixya!!

Wiring on the old one, "X", probably a brown wire will not be used on the new stat. If it's a blue wire, this may be your common. "E" and "W2" probably wired together with a white wire, this controls electric heat. "R" with a red wire, this is 24 volt power. "O" is an orange wire, this is the reversing valve. "Y" is a yellow wire, this is the contactor. "G" is a green wire, this is the blower. This pretty accurate? On the new stat, the jumper should be connecting "RH" to "RC/R", leave it in and wire the "R" from your old one to either terminal. White from the old one will go to the "E" of the new one. If your electric heat doesn't work after the install, you may need to jumper the "W1" and "W2" with the "E". "O" wires to "O". "Y" from the old one wires to the "Y1" of the new. "G" wires to "G". "C" on the new one is common. Usually a blue wire goes here. If "X" on the old one was blue, plug it into the "C". If it was brown, I'd suggest not using a common, and installing batteries. Hope this helps.
