I am converting a fridge into a fermenter box. I am looking for a thermostat that I can buy that can run the fridge compressor and heat source as temperature dictates. I read about a 2 stage johnson controls a-19 that you plug the fridge into one outlet and the heat into the other, but can only find single stage and youtube instructions on how to build heat control yourself. I have been building this thing (homebrewery) for about 10 months, and now I am tired of building and ready to buy plug and play temp control. Suggestions or links apreciated.
Thanks
