A dehumidistat is for use ONLY when the house is unoccupied. We were told to set ours at 60% humidity when we're not there and that it's conceivable that the inside temp could go even to 90° and higher but the a/c won't come on unless the dehumidistat senses the humidity going higher than 60% (which is the point at which you run the risk of mold). That is how the savings are effected: less use of a/c which runs ONLY to keep the humidity down. When the house IS occupied, you set the temp to your comfort level and turn the dehumidistat off.
