VAV Controllers

2326 Series

The 2326 Series Reset Volume Controller is designed to control the air volume through air terminal units. It controls the velocity and the output volume of these units between preset high and low limits, and responds to changes in the branch pressure of a pneumatic device. In effect, the 2326...

CSC-2000 Series

The pneumatic CSC-2000 series are designed for use on VAV terminal units in HVAC systems. These are ifferential-pressure, submaster controllers with adjustable minimum and maximum airflow settings. A master controller, typically a room thermostat, resets the CSC velocity setpoint.

CSC-3000 Series

These “universal” reset volume controllers are designed for use on heating or cooling systems with normally open or normally closed VAV terminal units. They are differential-pressure, sub-master air velocity controllers. Each is equipped with separate adjustment knobs for minimum and maximum...

P-3800

The P-3800 Reset Volume Controller regulates the flow of air in Variable Air Volume (VAV) boxes. The P-3800 controls the output volume, between adjustable minimum and maximum limits, in response to a reset signal from a thermostat or some other master controller. The P-3800 is available in two...

SSS-1000 Series

These sensors are designed to sense differential pressure in the inlet section of variable air volume terminal units and fan terminal units. They can also be used to sense differential pressure at other locations in the main or branch duct systems. The differential pressure read between the high...
