Thermostat Wiring

Hello everyone -

I am replacing an old RiteTemp 8085c with a Honeywell RTH6530D Thermostat

On the thermostat I am replacing, the following wires were connected:
C (blue)
W2 (white)
RC (red)
O (orange)
RH jumpered to RC
W jumpered to Y
Y (yellow)
G (green)

My options on the new Honeywell - if I try to match are as follows:
L
Aux/E (W, W1, W2)
G
O/B
NOT USED
Y R
Rc (Jumpered to R)

The honeywell manual says to leave C unconnected
my question is about the W, W2 and Y -
I assume my old W2 will go to AUX
but what about my old jumpered Y-W combo?
