Is there any documentation on what Mitsubishi's own MHK2 units can do, how well these libs replicate it, and how third-party thermostats factor into that equation?

I recently had a Mitsubishi heat pump installed, and I'm underwhelmed by the 1999-esque stock thermostat, but the vendor swore on the proverbial stack of Bibles that it was the only one that could properly run the unit as it was designed given all the proprietary control laws and so on.
