Pentair Intellicenter upgrade from Hayward

[proveg]

Hi all, got a pentair intellicenter from EBay and seems that it may have been partially installed, but never completed.
I am concerned that it was a faulty system and they just abandoned the installation and sold it.
I did get a deal, but concerned something maybe off, seems to be missing one relay.
So the question how can I test without taking my system off? Can I bench set it up? Anything I can try to test?

Looking at the control panel, can’t seem to find a matching wire with a connector.
Was there supposed to be an antenna? Anything missing?

I think that system was used as a parts donor. Did the seller attest that the system worked?

I had a storm blow out my IntelliCenter and I was close to buying a new bundle to get parts. Individual parts are expensive or not available. Buying a complete bundle and then selling off the parts not needed is more cost effective.

The transformer circled should have four red wires coming out of the top running into the low voltage compartment above and have a white connector that plugs into the power connector of the board. It looks like that is missing.

Below your pics is a pic of my board with the connecter circled.
