The part numbers are also listed several posts latter.
I believe that it is a Vintage Air Gen II compact. I am not sure if it will do all of the items you ask about - defrost, mixing, variable fan, etc. I have not investigated all that much.
The Gen IV Magnum will do everything you ask for sure and interfaces with the ISIS touch screen if you want to. However, this is bigger then the compact and I am not sure it will fit.
