I went to the Ranco mother page and clicked on
I called the factory to get some information and I'm telling you, the guy knows less than my daughters when it comes to controls!
He didn't understand what I was talking about when I mentioned to him that I wanted some ranges of stats that meet a constant cut in and adjustable cut out with the bulb IN the evaporator.
Heres the page of the Corporation, and if you try to get anything from Ranco good luck, everything on the web is junk. I can see why many companies such as McCall are switching.
