The Johnson Digital Controller operates by overriding the internal thermostat in a refrigerator or freezer which gives the brewer greater control over fermentation temperatures. It can be used to heat or cool a fermentation environment when hooked up to a refrigerator. It turns the compressor on when the ambient temperature rises above your programmed temperature. When it is hooked up to a heater, it activates when the temperature drops too low. A sensor probe monitors the temperature inside while the readout displays it in either Fahrenheit or Celsius. Features: 6ft extension cord with plug, 6ft sensor leads, and an easy to read LCD display. No additional wiring is necessary to install the unit. Simply plug the controller into an outlet, and plug your appliance into the controller.
