Digital a/c and heat works very poorly oftentimes in large buildings, because it's not adequately differentiated, and decides to keep one particular part of the building happy, screwing the rest of the building over.
For example, my bookstore has a digital a/c that keeps floors LL and 2 the same, and 1 and 3 the same. IE, if it's cooling LL, it's cooling 2, and vice versa; 1+3 are seperate. It's that way mostly so that the A/C doesn't die trying to cool all 4 floors ...
... minor problem, however. LL is ... um ... underground, of course, and thus pretty cool no matter what, comparitively; 2 is not only above ground, but is mostly a ceiling (there's a lot of airflow from 1 up to 2 and LL up to 1 (and 2), but there's much less from 2 to 3), and thus heat rises, AND the Café is on the 2nd floor, which of course is 5º to 15º higher (F) at any given time ...

Sounds suspeciously like a wet T-shirt contest.
