 And a lot of them say just leave it on. But I'll tell you, at my house, I put that thing on auto, and I can lower my humidity level. Last year, I was setting my air conditioning at like 72 degrees because it would be humid in the house. After this caller, I put that thing on auto. My air conditioner this year is set at 78. I leave it 78 all day and all night. I don't change it.
