Ok thats fine.. So are you using the CHE & UTH on the warm side? The reason I ask is that the CHE takes a long time to heat the tank up (if you remove the lid it starts all over) but as it gets hotter and hotter if its above a hide then that Hide can turn into a oven.... But you also mentioned a timer? I might of missed that post, whats the timer for? You want the CHE to run 24/7 to hold temps..
