Honeywell HP972B1005 Pneumatic Humidity Controller 2-Pipe Reverse Acting

The Honeywell HP972B1005 is a pneumatic humidity controller designed for use in 2-pipe HVAC systems with reverse acting control. This controller uses compressed air to regulate humidity levels in commercial and industrial environments, providing reliable control without requiring electrical power at the control point.

Key Features:

• Reverse acting pneumatic control for 2-pipe heating/cooling systems
• Pneumatic operation eliminates need for electrical wiring at sensor location
• Durable construction suitable for commercial HVAC applications
• Compatible with Honeywell pneumatic actuators and control systems
• Adjustable setpoint and throttling range for precise humidity control

This controller is ideal for applications requiring humidity control in commercial buildings, industrial facilities, and other environments where pneumatic control systems are preferred. The reverse acting configuration increases output pressure as humidity decreases, making it suitable for humidification control applications.
