Johnson Controls' A421ABJ-02C Line-Voltage Type 1 Electronic Temperature Control with Single Power Cord and Piggyback Plug lets you convert any freezer into a kegerator or fermentation chamber by overriding the appliance's thermostat, giving you precise control over the temperature settings. The device comes factory wired with a 6 ft. (1.8 m) cord with 120 VAC grounded piggyback plug with both a male plug and a female outlet. To use, simply plug your appliance into the female outlet and plug the male plug into an electrical outlet. The intuitive three-button touchpad allows for easy setup and adjustment, while the adjustable backlit LCD display lets you view the temperature and the status of other functions. You can view the temperature in either Fahrenheit or Celsius, and adjust the temperature between -40 to 212 degrees Fahrenheit or -40 to 100 degrees Celsius. An LED light lets you quickly check the On/Off status.
To give you even more control over your appliance's cooling and heating, the A421ABJ-02C was designed with convenient features like sensor offset to let you adjust the displayed temperature to the actual sensed temperature, switch-activated temperature setback to allow you to shift the on/off temperature by an adjustable setback value, adjustable anti-short cycle delay to allow you to select the minimum time that the output relay remains on before the next on cycle, and an optional restricted user adjustment mode to let you restrict the on/off adjustment to your defined temperature range.
The A421ABJ-02C is suitable for many refrigeration and HVAC applications, including agricultural, beverage, food service, ice machine, process, refrigeration, space heating, and ventilation applications. It has a durable Type 1 (NEMA)/IP20 high-impact plastic enclosure for DIN rail and surface mounting, and features an A99BB-200C temperature sensor with a standard 2 in. (5.1 cm) probe and a 6.6 (2.0 m) PVC cable.
