Vince - yes we have this adjuster (it is called a thermsistor I believe) in our rig (2012 Silverback) in addition to the cold-coldest buttons.
There has been quite a bit of discussion about this recently. I suggest you do a search for more information - I might have not spelled thermsistor correctly.
