1. A pump controller for providing an adaptive pump control to reduce energy consumption and operating cost of a heating and water cooling system, comprising:
- a signal processor configured at least to;
receive signaling containing information about a linear set point control curve derived from adaptive and constant set point control curves related to fluid being pumped by a pump in a pumping system, anddetermine corresponding signal containing information about a control set point to control and vary adaptively the speed of the pump in the pumping system using an adaptive control algorithm that obtains the control set point from the linear set point control curve derived, 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.

12. A method for using a pump controller for providing an adaptive pump control to reduce energy consumption and operating cost of a heating and water cooling system, comprising:
-
receiving in a pump controller having a signal processor signaling containing information about a linear set point control curve derived from adaptive set point and constant control curve related to fluid being pumped by a pump in a pumping system, and determining in the pump controller corresponding signaling containing information about a control set point to control and vary adaptively the speed of the pump in the pumping system using an adaptive control algorithm that obtains the control set point from the linear set point control curve derived, based at least partly on the signaling received. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
