Most of the high end units for any manufacturer utilize communicating controls.
Some of the communication protocol is proprietary.
I had to buy a "dumb" condensing unit for a friend last spring. All I needed it to do is turn on when I sent 24 vac to the contactor from the furnace. Coleman is the lesser brand name of York.
This unit had a scroll compressor and was listed as slightly higher noise levels than the higher end. Turns out the higher end had a compressor sound blanket. I bought an aftermarket sound blanket and you can hardly hear the compressor/unit run.
