Description
The Johnson Controls A19ACA-14C is a single-stage temperature control for HVAC/R systems, sensing temperature through a bulb-and-capillary element. It operates an SPST switch that opens on a temperature drop, and its manual reset requires an operator to restore the control before it returns to service.
Its liquid-filled sensing element uses a 3/8 in. by 4 in. bulb joined to a 6 ft capillary line. A screwdriver-slot adjuster sets the control point across the -30 to 100°F (-34 to 38°C) range, while the bulb itself withstands exposure to temperatures up to 140°F (60°C).
