I use the same setup in my cellar. Here's what I do.
The Johnson is in heating mode. The set point is the “cut out” temperature, and the differential is set to 2 °F. This means, since the cellar is cold, that the temperature of the beer falls until it is 2 °F below the set point. Then the thermostat turns the heater on until it reaches the set point. That means that the beer will ferment at 66 ± 1 °F if I set the controller for 67 °F.
Does that help?
Yes. So this means I should change it from cut in to cut out? What is it doing when it's in cut in?
