Watertight Electronic Temperature Control with Single Power Cord and Piggyback Plug

Johnson Controls' A421AEJ-02C Type 4X Electronic Temperature Control with 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 4X is made from corrosion-resistant high-impact thermoplastic that is watertight, making it ideal for areas that may need to be washed or watered down. 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, parameters 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 A421AEJ-02C was designed with convenient features like sensor offset to let you adjust the displayed temperature to the actual sensed temperature and switch-activated temperature setback to allow you to shift the on/off temperature by an adjustable setback value. It also comes equipped with 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 A421AEJ-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 4 (NEMA)/IP66 watertight corrosion-resistant enclosure for surface mount applications, 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.
