I recently was given a few thousand dollars worth of brewing equipment from my uncle who passed away. I cannot figure out how this works obviously its some sort of temp control he built. Im hoping someone can point me in the right direction. Also included 2 ranco temp controllers. 220 comes into this box and is wired as pictured. I would assume the 220 coming out of the box is for the heating element. But i do not know how this is supposed to work with the temp controller as they are 110.
