Well right now there is no cool end. It's 84 ambient with surface temps around 86. When I realized I had a problem with the uth the cool end was below 70. But it was cold outside and i have a cold house in general. Im thinking I need to do both. It's warming up here and bit so I think I'll fire up the uth with the new thermostat and see what the cool side does. I do have the che on a dimmer also.
