New Carrier Cor wiring

Any help on the wiring for this?

I currently have wires on a basic Honeywell thermostat as follows.
G
C
R
W1 jumper with Y
W2 jumper with E
O

New Carrier Cor thermostat has the following terminals:
Rc
G
Y/Y1
W1
O/B
Rh
C
Y2
W2
ACC+
ACC-

Any suggestions? Carrier offers crap for support. I'm thinking if I follow the normal wiring and use Rh (for just my R wire) and create a jumper from W1 to Y I will be fine. But the new unit has no E terminal to jumper from w2.

What should I do?

The jumper between Y1 and W1 is not required with the new thermostat.

Page 20 of the manual shows your application.
