Equipped with Sensorless technology, a Design Envelope pump's performance characteristec curve (power draw and rpm) and operating curve are pre-programmed into the controller. During operation, the controller monitors the power and sprred of the pump and establishes the hydraulic performance and position of the pump's head-flow condition relative to the system requirements. As the building's control valves open or close to regulate the flow to the cooling coils and maintain building occupant comfort, the Sensorless controller automatically adjusts the pump speed to match the required system pressure and flow.
