Description

  • The Johnson Controls PENN A421 Single-Stage Digital Temperature Controller is an industrial-grade, line-voltage micro-processor module engineered to provide absolute accuracy and programmable flexibility across demanding commercial refrigeration and heating applications.
  • Operating universally on 120V or 240V AC power inputs, this premium SPDT controller incorporates an adjustable 1°F to 30°F switching differential to seamlessly regulate heavy-duty compressors, hydronic valves, or ventilation fans based on continuous ambient data.
  • The rugged NEMA 1 enclosure features a high-brightness backlit LCD screen and a secure three-button touchpad that allows field technicians to enforce strict anti-short cycle compressor protection parameters and sensor calibration offsets while restricting unauthorized customer adjustments.
  • Ideal for HVAC/R service mechanics, property facility managers, and electrical contractors, the A421ABC-02C kit includes a factory-calibrated 6.6-foot A99BB sensor probe and supports dual DIN rail or surface mounting to deliver reliable, fail-safe climate loop management.
