About Johnson Controls A421AET-01C Penn Series A421
The A421 Series Electronic Temperature Controls are single-stage controls with a single-pole, double-throw (SPDT) output relay, a bright backlit LCD, and a three-button touchpad interface that can be set up to restrict user adjustments. An LED indicates the output relay's On/Off status. The A421 Series Controls have simple On and Off temperature settings for heating or cooling, an adjustable anti-short cycle delay, and a temperature offset function. The control range is -40 to 212°F (-40 to 100°C) for standard models. Models with a control range of -40 to 248°F (-40 to 120°C) are available in quantity orders. The controls feature remote sensing capability and interchangeable sensors. The A421 Controls are available in either Type 1 (NEMA)/IP20 high-impact plastic enclosure suitable for surface or DIN rail mounting or Type 4X (NEMA)/IP66 watertight, corrosion-resistant surface mount enclosures. The A421 Controls with Integral Cycle Timer provide On/Off control of ventilation fans in agriculture applications, warehouse and storage facilities, and other ventilation application that require air-exchange based on temperature or a ventilation schedule with a user-defined On-time and Off-time cycle.
