Johnson Controls A19EDB-1C Fan/Cut-Out Temperature Control

Johnson Controls A19EDB-1C Fan/Cut-Out Temperature Control offers precise duct temperature control for HVAC systems. The SPST duct temperature control operates over a 100–350°F range with a manual reset, ensuring safe, reliable operation. An open-high switch provides fail-safe protection, while a 5-inch probe delivers accurate sensing across ductwork, enabling tight control of fan activation and cut-out switching.

Engineered for compatibility with standard air-handling components, this controller supports efficient energy management and consistent comfort in commercial environments. Use it to trigger fans or cut-out devices when duct temperatures rise above setpoints, reducing wear and maintaining safe temperatures.
