Subj : Re: visi-therm deluxe adj To : All From : Rich Grenfell Date : Sun Jan 04 2004 02:58 pm Hi Al, being that you bought it recently, i'd say that it's the new adjustment method. Old visitherms had that red thing that just slid up and down the temp display when you turned the adjustment knob. now they have a click stop feature (meaning that there are notches inside the heater that stop the adjustment at precisely where you want them to). The reason for the new feature, is that the old ones would slip out of adjustment after a while, and the temp would drop in your tank. The click stop feature stops this from happening, but it is a bit harder to adjust. If you have one of the old models, then yes you have one that is a bit unusual. Hope that helped!!
