Welcome, Red! If you get a chance, give us a first name and where you hale from in your signature line! We're kind of informal around here, and like to know our new friends.
Some of the internal temps you may have been seeing could have been caused by probe placement, and the normal temperature swings you get with the analog controller. Unless you were staring at the temp the entire time, I would bet that it occasionally went above the set point. The swings generally go above and below, but average-out to the set temp. Nature of the beast with a rheostat controller.
Before adding the Auber, I recommend spending some quality time over at the "Auber Tips and Tricks" section of the forum. There is an incredible amount of trial and error knowledge there. We've gone through all the growing pains, so you won't have to. There are several instructional posts on everything you'll need. Look through there, and then hit us with any questions!
