Abstract: The present invention provides apparatus, including a hydronic sensorless pumping system, that features a signal processor or processing module configured to receive signaling containing information about motor readout values of power and speed, and also about pump and system characteristics equations together with empirical power equations that are constructed by a polynomial best-fit function together with pump affinity laws based upon a pump curve published by a pump manufacturer; and determine corresponding signaling containing information about a pump or system pressure and a flow rate at the motor readout values of power and speed, based upon the signaling received.

Abstract: The present invention provides apparatus that features a signal processor or processing module configured to receive signaling containing information about an adaptive or self-calibrating set point control curve and a varying equivalent system characteristic curve based at least partly on an instant pump pressure and a flow rate using an adaptive moving average filter, and equivalent hydronic system characteristics associated with the instant pump pressure and the flow rate to corresponding motor power and speed reconstructed and remapped using a discrete numerical approach; and determine an adaptive pressure set point, based at least partly on the signaling received.

Abstract: Apparatus, such as a pump controller, features a signal processor configured at least to: receive signaling containing information about a linear set point control curve based at least partly on an adaptive set point control curve related to fluid being pumped by a pump in a pumping system, and determine a control set point based at least partly on the signaling received. The signal processor may be configured to provide a control signal containing information to control the pump based on the control set point determined.
