KMC Controls CSC-2009 Control

The KMC Controls CSC-2009 is a high-precision pneumatic VAV controller designed for baseline air volume management in terminal unit applications. Engineering a reliable environment starts with the CSC-2009 Reset Volume Control, which operates as a sub-master differential pressure controller to maintain consistent VAV air flow settings regardless of changes in system static pressure. This specific model features a 0-2" WC range and is configured for Direct Acting (DA) operation, making it the standard choice for normally open damper configurations in commercial HVAC systems. The integrated mounting bracket ensures secure installation on the ductwork or plenum, providing the stability needed for accurate pneumatic velocity control. With local adjustable minimum and maximum limits, this reset volume controller integrates seamlessly with room thermostats to provide dynamic HVAC air volume management and optimize pneumatic energy efficiency in complex air distribution systems.

Key Benefits:

• Precise Airflow Regulation: Maintains a 0-2" WC differential pressure range for consistent terminal unit performance.
• Field Adjustable Limits: Separate adjustment knobs allow for exact calibration of minimum and maximum VAV air flow setpoints.
• Sub-Master Design: Responds accurately to master controller signals for effective pneumatic reset control.
• Durable Construction: Built with robust ABS materials to withstand standard industrial HVAC operating environments.
• Ease of Installation: Includes a heavy-duty mounting bracket for professional, vibration-resistant placement.

Common Questions:

What is the difference between direct and reverse acting models?
The KMC CSC-2009 is a Direct Acting (DA) model, which is typically used for normally open VAV terminal units where higher branch pressure from the thermostat results in increased airflow.

Can the setpoint range be adjusted in the field?
Yes, the CSC-2009 features blind adjustment knobs for both minimum and maximum velocity limits, allowing technicians to calibrate the pneumatic controller to specific site requirements using standard airflow measuring tools.

Is clean air required for this device?
Absolute maintenance of the pneumatic supply is critical. This KMC Controls pneumatic device must be supplied with clean, dry, oil-free control air to prevent internal clogging and ensure the differential pressure sensor maintains long-term accuracy.
