Description:
The P-3800 Reset Volume Controller is a pressure independent, submaster device designed to regulate the flow of air in Variable Air Volume (VAV) boxes. The P-3800 controls the output volume, between adjustable minimum and maximum set points, in response to a reset signal from a thermostat or some other master controller. Two models of the P-3800 are available to satisfy all VAV/thermostat configurations, in both cooling and heating applications. In addition, the design of the P-3800 provides accurate air volume control, even down to a velocity pressure as low as 0.01 in. WG (2.5 Pa), despite the varying supply pressures found in many systems today. The constant reset span feature of the P-3800 means the unit will maintain the desired volume setting regardless of static pressure and/or zone load fluctuations, thus saving energy and improving the comfort level of the environment being controlled. In addition, the reset start point, reset range, and minimum and maximum flow set points of both models of the P-3800 are fully adjustable, allowing the installer to customize the unit to match the application, as dictated by the system drawing. Refer to the Specifications table for adjustment ranges and factory settings, as well as other reset controller specification information.from our fans
