Attempt to install nest on Bryant

[bbooska]

The only paperwork I could find regarding model was BA13 and a couple others that shared the same paper work. I hooked the nest up as shown first with the Brown wire in the O/B spot then in the W2 spot. I couldn't get a single function to work, heat, heat2, AC or fan, and was forced to put the old thermostat back on. Can't find what the ACC+ brown wire should go to or why not a single function worked. I figured if I had a wire in the wrong spot it would at least run a few of the functions. Anyone know how to wire it?
