A19ADB-11C Johnson Controls Temperature Control

Overview

The Johnson Controls A19ADB-11C is a single-stage remote bulb temperature control designed for utility applications in farm, industrial, and commercial settings. It features a liquid-filled sensing element and capillary to provide precision tracking and control of temperatures across a wide operating range. The unit incorporates a manual reset feature that locks out at high temperatures, requiring physical intervention before operation resumes.
