Please help with Thermostat wiring

I know this must be asked a million times, but upon searching for the answer I'm still unsure how to wire my new thermostat

My old thermostat is a Hunter 44428
My new one is a Z-wave honeywell TH8320zw

Old Thermostat and how it's currently wired


New thermostat plate



So I currently have:
- R
- Y1
- W1
- W2
- G
- O/B
- E
- C

I'm assuming the following
- R goes to R
- Y1 goes to Y
- W1 .......I have no idea
- W2 goes to Aux
- G goes to G
- O/B goes to O/B
- E goes over to E
- C goes to C

Any help would be immensely appreciated

I would put the old W1 into the new Aux slot.

I'd tape off the old W2.

You must also configure the new stat for heat pump with Aux heat operation.
170 = 7

You must also configure the O/B terminal to match your outdoor unit.
190 = 0 for Almost every heat pump except Rheem, Ruud and Weatherking.
190 = 1 for those names.
