Abstract: This invention continuously monitors the differential pressure between two environments, and dynamically adjusts the air handling system of the controlled environment to maintain a desired differential pressure setpoint by using a closed loop control methodology. Local and remote users can initialize, configure, monitor, and readjust the differential pressure setpoint as necessary. A differential pressure sensor transmits data to the system controller for processing and analysis. The system controller interfaces to a wide variety of air handling systems by using interchangeable air handling subsystems that plug into the invention. Each subsystem has the necessary hardware interface and software control methodology to easily and transparently enable the system controller to interface with a wide variety of air handling configurations.
