Johnson Controls A19ABC-82 Thermostat

The Johnson Controls A19ABC-82 is a heavy-duty single-stage temperature control designed for versatile applications in HVACR systems. This SPDT (Single-Pole, Double-Throw) utility thermostat provides reliable switching for line-voltage circuits, making it suitable for both heating and cooling equipment. Featuring a broad 100?F to 240?F temperature range, the A19ABC-82 utilizes a 6-foot copper capillary and remote bulb to ensure precise liquid-filled thermal sensing. For contractors looking for a drop-in replacement, the A19ABC-82 is identical to A19ABC-82C, maintaining the same electrical ratings of 120/208/240 Vac. The knob setpoint adjustment and automatic reset functionality allow for rapid field calibration and consistent operational cycles in demanding commercial environments like boilers, tanks, or process piping. This electromechanical control is a standard for technicians requiring a robust remote bulb thermostat that delivers repeatable accuracy without the need for external power sources.

• Universal Application: Operates on 120, 208, or 240 Vac, allowing for standard integration across multiple power configurations.
• High-Temperature Versatility: The 100/240 degree range is ideal for high-limit or operating control in hot water and steam systems.
• Durable Sensing Element: Heavy-duty 6' capillary provides the reach needed for remote mounting while the liquid-filled bulb ensures rapid response.
• Contractor-Friendly Design: Features an accessible knob for quick setpoint changes and a clear scale for simplified field adjustments.
• SPDT Switching: Simplifies wiring for either "open on rise" or "close on rise" logic using standard terminal connections.

Is there a difference between the A19ABC-82 and the A19ABC-82C?
No, these model numbers are functionally identical. The "C" suffix typically denotes a contractor-packaged or retail-labeled version of the same technical component.

Can this be used for both heating and cooling applications?
Yes. Because it utilizes an SPDT switch, you can wire the common terminal to either the heating or cooling load depending on your specific requirements.

How do I adjust the differential on this model?
The A19ABC-82 features an adjustable differential (typically 6?F to 24?F). To set it, remove the cover and adjust the internal lever to the desired temperature spread before putting the system into operation.
