Johnson Controls A19ADB-29 Dual Stage Temperature Control 90-325°F SPST

The Johnson Controls A19ADB-29 is a dual-stage temperature control designed for commercial and industrial HVAC applications. This automatic reset line voltage thermostat provides reliable temperature control across a range of 90°F to 325°F, making it suitable for heating applications and high-temperature environments.

Key Features:

• Temperature range: 90°F to 325°F
• SPST (Single Pole Single Throw) switching configuration
• Manual reset function with open-on-rise operation
• 10-foot capillary sensing element for remote temperature sensing
• Line voltage control for direct equipment switching
• Durable construction for commercial applications
• Fixed differential for consistent temperature control

This thermostat features a 10-foot capillary tube that allows the sensing element to be positioned remotely from the control housing, ideal for duct mounting or applications where the sensor needs to be placed away from the switching mechanism. The open-on-rise operation means the contacts open as temperature increases, making it ideal for cooling control or high-limit protection.
