What is the warmest a room should be to ferment without damaging the wine.

Wine yeast is very different than beer yeast. With beer, the character of the beer depends a lot on the yeast. With wine, you try to minimize the influence. Think ale vs. lager here.
I am not a wine maker, only a beer brewer, but I would look up the yeast characteristics and see the recommended fermentation temperature.
