Johnson Controls Electronic Temperature Control with Dual Power Cords

Convert any freezer into a kegerator or fermentation chamber using Johnson Controls' A421ABG-02C 120 VAC Type 1 Electronic Temperature Control with Dual Power Cords, which gives you the power to override an appliance's thermostat to give you precise control over the temperature settings. To use, simply plug your appliance into the 6 ft. (1.8 m) power cord with 120 VAC grounded female outlet and plug the 6 ft. (1.8 m) power cord with 120 VAC grounded male plug into an electrical outlet. You can then use the intuitive three-button touchpad for setup and adjustment and view the temperature and the status of other functions on the adjustable backlit LCD display. The temperature can be displayed in either Fahrenheit or Celsius, and the temperature adjustment range is -40 to 212 degrees Fahrenheit or -40 to 100 degrees Celsius. An LED light allows you to check the On/Off status at a glance.

Not only does the A421ABG-02C provide superior heating and cooling control, but it also comes loaded with convenient features like sensor offset to allow you to adjust the displayed temperature to the actual sensed temperature, switch-activated temperature setback to let you shift the on/off temperature by an adjustable setback value, adjustable anti-short cycle delay to let you select the minimum time that the output relay remains on before the next on cycle, and an optional restricted user adjustment mode to allow you to restrict the on/off adjustment to your defined temperature range.

The A421ABG-02C has many other refrigeration and HVAC applications, including agricultural, beverage, food service, ice machine, process, refrigeration, space heating, and ventilation applications. It has been designed with a durable Type 1 (NEMA)/IP20 high-impact plastic enclosure that is suitable for DIN rail mounting or surface mounting, and includes an A99BB-200C temperature sensor with a standard 2 in. (5.1 cm) probe and a 6.6 ft. (2.0 m) PVC cable.

• Control Front Panel LCD:
  Displays the temperature, parameters, and status and allows you to adjust the backlight intensity for ambient light conditions. Custom icons display the system and control status.
• Basic and Advanced Programming Menu:
  Provides two levels of parameter adjustment and control setup, allowing you to set up advanced features in one menu and easily adjust basic parameters in the other menu.
• On/Off Temperature Adjustment:
  Allows you to select the temperature values at which the relay turns On and Off, which automatically defines the Heating and Cooling mode of operation.
• Switch-Activated Temperature Setback:
  Allows you to switch the On/Off temperature by an adjustable setback value. When a user-supplied switch closes the binary input control circuit, the control operates at the defined setback temperatures.
• Adjustable Anti-Short Cycle Delay:
  Allows you to select the minimum time the output relay remains off before the next on cycle; avoiding short cycling, hard starts, and nuisance overload outages on compressors and other inductive applications.
• Adjustable Sensor Offset:
  Allows you to adjust the displayed temperature to the actual sensed temperature.
• Optional Restricted Adjustment Mode:
  Allows you to restrict the On/Off adjustment to your defined temperature range.
• Sensor Failure Mode:
  Allows you to select the relay On/Off state in the event of a sensor or sensor wire failure.
• Backlight Brightness Level:
  Allows you to adjust the LCD backlight intensity.
