If in between samples you go from above max to below min you'll have both heat and ac on.
The take-away is that like programming lift controllers[0] it's not quite as simple as it might first seem - many many edge cases.

I actually wrote a finite state machine specification for an elevator in a logic class once. Without having really thought about it much, it looks like the biggest problems with thermostats are dealing with scalars, sampling frequencies, and sampling error.
