The KMC Controls CSC-2008 is a high-performance pneumatic VAV controller designed specifically for sub-master air velocity regulation in HVAC systems. This reverse-acting (RA) unit is engineered to manage normally closed (NC) terminal unit dampers, providing precise airflow modulation within a 0-1 inch WC setpoint range. Featuring a low consumption design with a typical air consumption of only 11.5 scim, the CSC-2008 minimizes energy waste while maintaining stable control in commercial and industrial settings. Internally, the reset volume controller utilizes a 3-8 psig reset signal from a master thermostat to adjust velocity limits, effectively balancing comfort and efficiency. Built with a durable ABS housing, the CSC-2008 VAV control includes independent adjustment knobs for setting minimum and maximum airflow limits, ensuring field-level flexibility during commissioning. This KMC pneumatic controller is cross-compatible with several industry-standard components, including the Robertshaw R77-26 and Trane X13190313010, making it a reliable choice for retrofits and system upgrades. Installers should note that for optimal accuracy, the unit must be calibrated in its final mounting orientation?Çöeither horizontal or vertical?Çöusing professional-grade differential pressure measuring equipment. Key Benefits Precise Airflow Regulation: Separate adjustments for high and low limits allow for exacting environmental control. High Compatibility: Direct replacement for various Trane, Carnes, and Robertshaw sub-master pneumatic units. Efficient Operation: Low consumption 11.5 scim rating reduces the load on the main air supply system. Durable Construction: UL Flame Class 94 HB ABS housing ensures longevity in rigorous mechanical environments. Common Questions Can this be used with normally open dampers? No, the CSC-2008 is specifically designed for reverse-acting / normally closed damper configurations. For normally open setups, a direct-acting model is required. What is the reset pressure range? This unit operates on a standard 3 to 8 psig reset band. Does this require a setpoint dial? No, this model features blind manual adjustments for a streamlined, tamper-resistant installation.
