The KMC CSC-2000 Series Reset Volume Controllers are designed for use on VAV terminal units in HVAC systems. The CSC-2000s are sub-master air velocity controllers with adjustable minimum and maximum velocity limits. A master controller, typically a room thermostat, resets the CSC velocity setpoint. Direct acting models are for normally open VAV terminal units. Reverse acting are for normal closed VAV terminal units. Each unit is equipped with separate adjustment knobs for minimum and maximum airflow settings. CSC-2001/2002s are equipped with 0–10 reference dials, while all others have blind adjustments. Calibrate all models using standard airflow measuring equipment.
These CSC-3000 Series Volume Reset Controllers are designed for use on heating or cooling systems with normally open or normally closed VAV terminal units. They are differential-pressure, sub-master air velocity controllers. Each is equipped with separate adjustment knobs for minimum and maximum airflow setpoints. Models are available with various reset start points. A master controller, typically a room thermostat, resets the CSC between the minimum and maximum velocity setpoints. These CSC-3000's universal design is intended for new or replacement applications that call for direct or reverse acting reset on normally open or normally closed VAV terminal units, using direct or reverse acting thermostats.
