as these factors influence the effective delivery range of the spring

the adjustable temperature differential and compressor short cycle protection ensure equipment longevity and prevent nuisance tripping in demanding HVAC applications

KMC Controls CSC-2007 Control 30067439-890 or the control board flashingFor technicians servicing VAV terminal units, the KMC Controls CSC 2007 is a trade standard pneumatic reset volume controller engineered for precision airflow management. Operating as a sub master velocity controller, this unit is built for direct acting (DA) cooling and normally open (NO) damper configurations. It features a specific differential pressure range of 0 to 1 inch water column (wc), making it ideal for low velocity applications where
