Use this handy controller to regulate the temperature in your freezer between 20º – 80ºF . Great for turning a chest freezer into a keg refrigerator.
Strictly a mechanical thermostat for cooling only, it is simple to use and economical. It operates with a gas filled probe on a 6-foot capillary tube. When the gas contracts or expands in the probe, it triggers a mechanical device inside the control which turns the power on or off.
There is no probe temperature readout on the dial, so keeping a thermometer inside the refrigerator is highly recommended to keep track of the actual temperature. On most refrigerators, the Controller will allow a usable range of 37 to 80 F., while on freezers, the controller will be able to reach its full 20º to 80º range.
*Keep in mind that if you use it to control a refrigerator, you will lose the use of the freezer compartment for food storage, as it will not stay cold enough for safe frozen food storage.
