KMC Controls CSC-3021-10 Control

Optimize your VAV terminal unit performance with the KMC Controls CSC-3021-10, a high-precision pneumatic reset volume controller engineered for professional HVAC applications. This sub-master air velocity controller features a universal design, making it a reliable choice for both cooling and heating systems utilizing normally open or normally closed dampers. As a veteran-grade differential pressure reset controller, it integrates seamlessly with direct or reverse acting thermostats to maintain precise airflow setpoints. The unit operates within a 15 to 30 psig main air range and a 0 to 1 inch WC differential pressure span, ensuring stable regulation even in demanding commercial environments. Experience simplified calibration with dedicated adjustment knobs for minimum and maximum setpoints, complemented by a factory-set 3 psig reset start point. Built with a rugged metal enclosure and including a heavy-duty mounting bracket, the KMC Controls CSC-3021-10 is the standard for contractors seeking durable, position-sensitive airflow management components for VAV boxes.

• Universal Application Compatibility: Designed to work with both DA and RA thermostats and NO or NC damper configurations, reducing truck stock requirements.
• Precise Airflow Regulation: Maintains consistent volume control across a 0 to 1?ǥ WC differential pressure range for improved occupant comfort.
• Simplified Setup: Equipped with independent knobs for minimum and maximum airflow adjustments and a pre-configured 3 psi start point.
• Industrial-Grade Build: Features a durable beige housing and a secure mounting bracket to withstand high-use mechanical room conditions.
• Flexible Installation: Position-sensitive design supports horizontal or vertical mounting to accommodate tight field constraints.

What air supply is required for the CSC-3021-10?
This controller requires a clean, dry, and oil-free main air supply between 15 and 30 psig to ensure optimal valve and actuator response.

Can the reset start point be modified in the field?
Yes, while this model is factory-set at 3 psig, the reset start point is field-adjustable from 0 to 10 psig to match specific sequence-of-operation requirements.

Does this unit include mounting hardware?
This specific 10-suffix model includes the standard mounting bracket, allowing for immediate installation onto the terminal unit or ductwork.
