text:  It doesn't bring the temperature down much. If I've got it at 78, it doesn't bring it down within an hour to 76 or whatever. You mean if you set it down to 76, it wouldn't do anything? From 78 to 76 if it's 110 out. It's keeping it just at that point of where it's at. It might take an hour or two hours to lower it a degree at that point.
