I verified the relays I purchased work as “expected”. I hadn’t realized I ordered latching relays but I did. No big deal, they’ll work but non latching would have been simpler as I will now need to utilize 2 GPIO ports per relay. I also did a little more research into wiring of my particular AC unit and believe I’m getting a better grasp on how it operates. More to come on this as I continue testing. On a side note, Adafruit got the touch screen in stock I wanted so I ordered that along with a but buttons and a case that may work for what I want with a few tweaks.
