RTH6580WF Install Question

I am trying to install a new wifi thermostat (Honeywell RTH6580WF).
I had an old Bradeburn thermostat (Model No 1200NC). On it, I had five wires as follows (Terminal/Wire color): W2/White, C/Blue, G/Green, Y1/Yellow and R/Red.
I looked up the support, etc provided by Honeywell, I connected the wires as follows to the RTH6580WF:
Old (Braeburn)=> New (Honeywell)
W2/White => AUX/E
C/Blue => C
G/Green => G
Y1/Yellow => Y
R/Red => R

I was trying to set it up and decided to call honeywell support to ensure something about the setup of functions appropriately. The support person informed me that if my system is a heat pump (which is what I was told it was when I had it installed), it has to have a wire going to W/O/B terminal. If not, it is not a heat pump.

When I had it installed (it was for upstairs) about 4 years back, I was informed that it is heat pump system (with auxillary/emergency heat). My Air handler in the attic is a Goodman ARUG303016AA and my outside compressor is also a Goodman CR18K7-PFV-230. I tried to look at the wires, but they seemed confusing to me as multiple wires coming out from the air handler were strung together and finally just 2 wires were going down the conduit (attached photograph).
Any suggestions or should I seek a professional to install it?
Thank you.

The outdoor unit tag may be by the refrigerant pipes.

From your wiring I can see that you do not have a heat pump.

That model dose not appear to be a heat pump, double check the nameplate on the condenser unit outside for a model number and check with Goodman Mfg. to be sure.
