I've been doing some research and i'm still really confused how some of these temperature controllers work. What I want to do is use an old fridge as a fermentation chamber and keep it at a steady temperature. I've checked out the Elitech STC-1000, the Johnson Controls digital thermostat control unit, and a couple Ranco ones. Basically my question is do I need to add a heating or a cooling unit to the fridge for the temp controller to function right? I would think, in the summer anyway, you wouldn't need a heating unit, just a cooling one. Does the fridge do the work for cooling? Sorry if these are dumb questions. Budget says that I have to do it right the first time.
