KMC Controls CSC-2017 Control

The KMC Controls CSC-2017 is a high-performance pneumatic VAV reset volume controller engineered for precise airflow management in commercial HVAC systems. As a differential-pressure sub-master controller, this unit is specifically designed for normally open VAV terminal units using a direct acting (DA) configuration. It features a 2-inch water column (WC) range with a low consumption design, ensuring optimal energy efficiency while maintaining rigorous pneumatic pressure standards. Managers and technicians can field-adjust the separate minimum and maximum airflow setpoints to meet specific zone requirements, providing a versatile solution for VAV box control applications. Built with a durable ABS housing and rated for operating temperatures between 40?? and 120?? F, the CSC-2017 integrates seamlessly with KMC thermostats and master controllers to reset velocity setpoints based on real-time demand. This model typically includes a mounting bracket and a paper label dial for clear, manual calibration during commissioning.

• Precise Airflow Regulation: Features separate adjustment knobs for accurate minimum and maximum airflow settings to optimize zone comfort.
• Fail-Safe Logic: The direct acting, normally open (DA/NO) operation ensures the damper remains open during signal loss for continuous ventilation.
• Low Air Consumption: Engineered to minimize pneumatic air usage, reducing the overall load on the facility's compressed air system.
• Industrial Durability: Constructed with UL Flame Class 94 HB material to withstand demanding mechanical room environments.
• Sub-Master Control Capability: Effectively resets velocity setpoints when paired with a master room thermostat for dynamic load response.

Which VAV box types are compatible with the CSC-2017?
This controller is designed for normally open terminal units. It uses a direct-acting signal where an increase in control pressure results in an increase in output to the actuator.

How do I calibrate the minimum and maximum airflow?
Technicians should use airflow measuring equipment to verify velocity while adjusting the dedicated minimum and maximum knobs located on the face of the unit.

What is the typical supply air pressure for this unit?
The KMC Controls CSC-2017 is rated for a main air pressure range of 15 to 30 psig, with an output capability spanning from 0 to the full supply pressure.
