So the CHE is as far to the right as it can possibly go unfortunately.I already have a UTH for the hot side with thermostat attached. Thermostat being used most definitely. I'm temp gunning ground twice a day to double check, and I have two accurite readers that tell me temps/humidity levels. One on cool side, and one on hot side. I find the readers show such a DRASTIC difference in humidity on each side. I can add another UTH on left side if needed. That isn't a problem. I wish I knew why I was struggling so badly to get the temps just right. The CHE is on a dimmer, and i find i adjust it slightly too high or slightly too low and can't quite find a happy medium.
