Thanks I have seen that and used a lot of that info when I set him up. But I had to turn off the uth and only use the che temporarily.
So it's not so much how to question so much as what's the best way to do it. I get that the uth will not heat the tank and since my cool end temps are to cool I'll probably need the che. So I guess my question is weather or not to use the uth or just maintain a general temp with the che.
