You should be able to run the ac at 82 and keep the must out. Try it at a higher temp and see how that works. If people are not going in and out of the condo I have found this works quite well for condo owners that away. In fact I have a friend that runs her place at 84 when she is away - but I wonder if that isn't too high.

Stinky, musty condos are the result if you turn off the air conditioning.
