Description
Honeywell LP920B1037 Remote Bulb Temperature Controller Overview
The Honeywell LP920B1037 is a pneumatic remote bulb temperature controller engineered for precise 2-pipe HVAC system control. Designed with a reverse-acting response, this controller is ideal for cooling applications where a rise in temperature decreases the output signal — making it a go-to solution for chilled water coils, air handling units, and commercial duct systems.
Key Features
- 2-pipe pneumatic system design for straightforward installation and reliable operation
- Reverse-acting control action — output decreases as temperature rises
- Temperature scale range: 30°F to 150°F for broad application coverage
- Bulb dimensions: 3/8″ diameter x 5-1/4″ length for accurate sensing in duct environments
- 5-foot capillary tube for flexible remote bulb placement
- Remote duct mount configuration for direct air stream temperature sensing
- Throttling range: 5–25°F, allowing fine-tuned proportional control
Application & Installation
The LP920B1037 is designed for remote duct mounting, where the sensing bulb is inserted directly into the airstream for accurate temperature measurement. The 5-foot capillary provides installation flexibility, allowing the controller body to be mounted away from the duct. Its adjustable 5–25°F throttling range enables technicians to dial in the right proportional band for stable, efficient system performance.
