Refrigerator Thermostat

Easy to install to household refrigerators. Allows an adjustment range of 30 degrees to 80 degrees F. The Johnson controller has an analog dial that you can set between 30 and 80°F, with 1 degree increments. There is a differential of 3.5°F and so the appliance will turn off and on a range of 3.5°F above or below the set temperature. These adjustments in temperature are too slight to affect your fermentation.

Tip: A worthwhile investment for anyone that is serious about nailing styles especially lagers. A brewer is essentially a yeast farmer/magician.
