Controller to maintain a certain set of environmental parameters in an environment

摘要: This invention continuously monitors the differential pressure between two environments, and dynamically adjusts air handling system of controlled environment to maintain a desired setpoint by using closed loop control methodology. Local remote users can initialize, configure, monitor, readjust as necessary. A sensor transmits data controller for processing analysis. The interfaces wide variety systems interchangeable subsystems that plug into invention. Each subsystem has necessary hardware interface software methodology easily transparently enable with configurations. flexibility allows voltage or current outputs solenoid driven valves, dampers, DC motors; handler phase, cycle, frequency AC motors.
