I am boing to build an e-HERMS/BK setup in my basement. I got to looking at the Ranco 2 stage controllers and began wondering if it would be possible to wire one of these up to control the HLT on the heating side while controlling a fermentation chiller on the cooling side. Even if you could only run the chiller when you weren't running the HLT. Would this be worthwhile or would I be better off buying 2 single stage controllers?
