I am a little confued on the wiring. I havea Trane XL15i with aux heat. I cannot seem to find out what the black and brown wires are for. The thermostat I am trying to connect is Honeywell thermostat model TH8320U1008. Here is what I have so far.
Blue wire to C
Brown wire ?
Orange wire to O/B
White wire to Aux
Red wire to RC+R (jumper installed)
Yellow wire to Y
Green wire to G
Black wire to E
Thanks

Follow page 4 for Typical hook up single stage heatpump 2H/1c
ignore the brown wire
