Johnson Controls A19ABC-80 Temperature Control

The Johnson Controls A19ABC-80 is a rugged, mechanical remote bulb temperature control designed for versatile HVACR applications. Engineered for reliability, this SPDT temperature switch features an automatic reset and a wide setpoint range of 50 to 130?F, making it an ideal utility thermostat for both heating and cooling equipment. The unit is equipped with a 3.5 to 14?F adjustable differential, allowing technicians to fine-tune system cycling for maximum efficiency. Its 8-foot capillary tube and 3/8" x 5" sensing bulb provide the reach and surface area necessary for accurate sensing in walk-in coolers, display cases, and industrial heating loops. This mechanical temperature controller supports a broad voltage range from 24 to 277Vac, ensuring compatibility with standard commercial electrical footprints. For those managing legacy inventory, the A19ABC-4 serves as the current direct replacement for A19ABC-80C configurations, maintaining the same form factor and technical specifications.

• Wide Voltage Range: Rated for 24Vac to 277Vac, standardizing your truck stock for various service calls.
• Field-Adjustable Precision: Customize the temperature swing with a 3.5 to 14?F adjustable differential to prevent short-cycling.
• Versatile Application: SPDT contacts allow the A19ABC-80 to function in both "open high" (heating) and "open low" (cooling) circuits.
• Robust Sensing: The 8' capillary length and large sensing bulb offer flexible mounting and high repeat accuracy.

What is the difference between the A19ABC-80 and the A19ABC-4?

The A19ABC-4 is the direct functional replacement for the discontinued A19ABC-80, featuring the same 50?130?F range and remote bulb specifications.

Can this control be used for both heating and refrigeration?

Yes, the Single Pole Double Throw (SPDT) switch configuration allows for wiring to either break or make a circuit upon temperature rise, supporting HVACR applications across the board.

Is this a manual or automatic reset unit?

This model features an automatic reset, which means the switch will automatically return to its normal state once the temperature crosses the differential threshold.
