thermostat wiring help

I bought a Venstar T1100REC, reciever and T1100RF wireless themostat for use with my 2 stage heat pump, but when I pulled the old themostat off the wiring did not match anything in the documentation.

The old themostat is a honeywell RTH3100C1002- 0823, and it has the following terminals connected
C
R
O
G
Y
Aux
Z

any help is much appreciated

I don't see a Z terminal.



Old = new
C = C
R = R
G = G
Y = Y
Aux & E = W2
O = O/B

HP = on
O/B = off

What size heat strip do you have?
