KMC Controls CSC-2002 Control

The KMC Controls CSC-2002 is a high-performance pneumatic VAV controller designed for precision airflow management in commercial HVAC systems. As a differential-pressure sub-master controller, it effectively regulates normally closed (NC) VAV terminal units by modulating damper positions based on 15 to 30 psig main air supply. This reverse acting unit features a 0 to 10 molded plastic dial indicator, providing technicians with a clear reference for field calibrations without the guesswork of blind adjustments. Engineered for VAV terminal unit applications, the CSC-2002 utilizes dual adjustment knobs to define exact minimum and maximum airflow settings, ensuring the system maintains design air volumes regardless of duct pressure fluctuations. Its gray ABS construction and compact footprint allow for seamless integration into existing pneumatic control loops, and it is frequently used as a reset volume controller when paired with a master room thermostat. To ensure optimal performance, this RA/NC VAV controller must be mounted horizontally with the dial facing upward.

• Precise Airflow Regulation: Features independent setpoints for minimum and maximum CFMs to prevent over-cooling or under-ventilation.
• Visual Field Calibration: The integrated 0-10 dial indicator simplifies the synchronization of the controller with actual duct velocity measurements.
• Universal Compatibility: Serves as a reliable replacement for Robertshaw R77-22 and Carrier HK08ZZ041 components in legacy pneumatic systems.
• Robust Pneumatic Logic: Operates efficiently within a 40?? to 120??F range, providing a reverse acting output sensitivity of 5 psig per 0.02" wg.

Common Questions

Is the KMC CSC-2002 compatible with normally open dampers?
No, the CSC-2002 is specifically a reverse-acting (RA) controller designed for normally closed (NC) terminal units. For normally open (NO) applications, a direct-acting model like the CSC-2001 is typically required.

What is the recommended mounting orientation for this controller?
For accurate differential pressure sensing, the KMC Controls CSC-2002 should be mounted in a horizontal plane with the molded dial and adjustment knobs facing up.

Does this unit require a master controller?
Yes, in standard VAV applications, a master controller such as a pneumatic room thermostat provides the 8 to 13 psig reset signal to the CSC-2002 to determine the velocity setpoint.
