KMC Controls CSC-3000 Series Reset Volume Controllers

Reset Volume Controllers
CSC-3000 Series

These “universal” reset volume 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.

Their 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. They can replace many other pressure independent controllers
