To have the temps on the cool side higher than normal as they shift? Right now, I don't have a stat on the cool side UTH of her tub and it's being controlled by a rheostat on a timer. During the day, those temps are fine and in just the right range. But at night, the UTH has to come into play.
The timer is set to come on for 15 minutes every hour(since that's the minimum it can be on for) and that has the temps fluctuating anywhere between 79 and 86...sometimes as high as 88. There's nothing else I can do about this at the moment, since I'm waiting on a new stat, but I was hoping that too high was a lot better than too low.
