Need help with a Honeywell RTH7600 Thermostat.

I installed a Honeywell RTH7600 thermostat everything is working but the heat pump.

Old wiring was hooked up as follows. B R G Y W2 X E, with a jumper going from W2 to E.

New wiring has C G Y O/B RC R AUX. E L to choose from. I need to know the conversions so I can check my wiring.

B = O/B (needs to be setup in new stat as B)
R = R & Rc
G = G
Y = Y
W2 = aux and E
X = C?

Your new thermostat MUST BE PROGRAMMED to operate as a HP system with aux backup for proper operation. Make sure you read the WHOLE manual.
