[quote]I am a first time user of the Ranco 2 stage. I have cooling set point at 65 with a 2 point differential. My confusion is the heat set point and differential. Anyone give me the proper way to set the Heat side?

I have the same controller, using it with a fridge and a fermwrap with a thermowell. If you want to ferment at say 67, you set the heat side to 67 with a 1 differential and the cold side to 67 with a 1 differential and you’ll be fine. You’re cooling a large enough mass (5 gallons or more of wort) that it wont cycle on and off constantly. Works like a charm.
