Changing Thermostat from Bryant Evolution to a Aprilaire 8600

[MCrumpacker]

Hello,

My old Bryant Evolution thermostat died and I purchased a new Aprilaire 8600 because they both have the same features. Problem is that I can't seem to figure out how to wire the new Aprilaire 8600. I have four wires on the Bryant furnace white, red, green and yellow. The white seems to be the neutral and the red is the 24 volt, not sure what the green and yellow are for but on the schematic for the Evolution it says that green and yellow are data. Anyone out there that has knowledge about how to wire this???

Thanks in advance,

White=call for heat, red= 24 volt supply, green= fan control and yellow= a/c compressor and normally there is a jumper from r-rc there is no neutral or common unless some one has run another wire
