KMC Controls CSC-3017-16 VAV Controller

The KMC Controls CSC-3017-16 VAV Controller is a high-precision, sub-master pneumatic volume reset controller designed for terminal units in commercial HVAC systems. This pneumatic VAV reset volume controller is functionally identical to the CSC-3011-10 but utilizes a bracketless design and arrives without an external logo for a streamlined, low-profile installation. It features an adjustable differential pressure range of 0 to 1" wg and a factory-calibrated reset start point of 8 psi. Built for versatility, this sub-master air velocity controller supports both direct and reverse acting reset, making it compatible with normally open or normally closed VAV terminal units. It is position-sensitive and must be mounted in a consistent horizontal or vertical plane to ensure setpoint accuracy. Technicians can field-adjust the minimum and maximum airflow settings to meet specific zone requirements while maintaining a constant reset span, ensuring reliable HVAC pneumatic controls performance across varying load conditions.

Key Benefits

• Universal Compatibility: Field-adjustable for normally open (N.O.) or normally closed (N.C.) damper actions and direct/reverse acting thermostats.
• Precise Airflow Control: Features separate non-interacting adjustment knobs for independent minimum and maximum airflow setpoints.
• Durable Construction: Housed in a UL Flame Class 94 HB ABS material, engineered for operating environments between 40?? and 120?? F.
• Streamlined Integration: The bracketless VAV controller design allows for flexible mounting in tight plenums where space is limited.

Common Questions

Does this unit include a mounting bracket?
No, the CSC-3017-16 is the bracketless and unbranded version of the CSC-3011-10. If a bracket is required, the HMO-4508 can be ordered separately.

What are the requirements for the control air supply?
This pneumatic device requires a clean, dry, and oil-free main air supply between 15 and 30 psig. Contaminants such as moisture or oil will cause the internal mechanisms to fail.

Can the reset start point be modified in the field?
Yes, while factory-set at 8 psi, the reset start point is field-adjustable from 0 to 10 psi to match the specific branch signal of the master thermostat.
