Johnson Controls A19AAT-2C Freezer Temperature Controller

Use this handy controller to regulate the temperature in your freezer between 20 - 80F . 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 20 to 80 F range. Features: Made of stainless steel. Adjustable with the turn of a knob. No drilling necessary. Plug unit into wall and then run the sensor into your freezer. Male and female plug in one.
