The Johnson Controls A19ABC-24 is a mechanical remote bulb temperature control designed for dependable temperature regulation in HVAC, refrigeration, and commercial temperature control applications. This control features a -30°F to 100°F setpoint range, making it suitable for low-temperature and moderate-temperature systems that require accurate automatic temperature control.

The A19ABC-24 operates on 24 to 277 VAC and uses an SPDT switching action for flexible control circuit applications. Its automatic reset function allows the control to return to normal operation after the temperature moves back within the selected range. With a 3°F to 12°F adjustable differential, this Johnson Controls temperature control gives technicians the ability to fine-tune cycling performance based on system requirements.

This model includes an 8-foot capillary length with a 3/8-inch x 4-inch sensing bulb, allowing remote temperature sensing away from the control body. The convertible range adjuster provides added installation flexibility, making the A19ABC-24 a practical replacement control for compatible HVAC and refrigeration systems.
