Description
The Honeywell LP920A1039 is a remote bulb temperature controller engineered for precise, reliable temperature regulation in commercial HVAC duct applications. Designed for 2-pipe pneumatic systems, this direct-acting controller responds to rising temperatures by increasing its output signal — making it ideal for cooling coil valve control and similar applications where a direct response to temperature change is required.
Key Features
- 2-pipe pneumatic system design for straightforward installation and operation
- Direct-acting control action — output increases as sensed temperature rises
- 30–150°F (–1 to 66°C) scale range for broad temperature sensing coverage
- 3/8″ x 5-1/4″ remote sensing bulb for accurate duct temperature measurement
- 5-foot capillary tube for flexible remote mounting of the sensing bulb
- Remote duct mount configuration keeps the controller accessible while the bulb senses in-duct conditions
- 5–25°F adjustable throttling range for fine-tuned proportional control
Application
The LP920A1039 is well-suited for controlling pneumatic valves and dampers in commercial air handling units, fan coil units, and duct systems where remote temperature sensing is required. The duct-mount design allows technicians to position the sensing bulb directly in the airstream while keeping the controller body accessible for adjustment and maintenance.
