The A421 Series Electronic Temperature Controls are single-stage controls with a single-pole, double-throw (SPDT) output relay. A421 Controls feature a bright backlit LCD with adjustable brightness 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. Standard A421 Series control modules have simple On and Off temperature settings for heating or cooling, an adjustable anti-short cycle delay, temperature setback, and sensor offset capability. The temperature control range is -40 to 212°F or -40 to 100°C. The A421 controls are available either in Type 1 (NEMA), IP20 (CE), high-impact plastic enclosures suitable for surface or DIN rail mounting or in Type 4X (NEMA), IP67 (CE) watertight, corrosion resistant surface mount enclosures.

The A421 Electronic Temperature Control can be used to control a wide variety of single-stage refrigeration or HVAC equipment.Sample temperature control applications can be found inside the product data sheet.
