FIELD: control systems.
SUBSTANCE: invention relates to a technology for controlling the operation of a pump and relates to a method and apparatus for controlling a pump and/or for its monitoring, in particular for water heating or cooling systems for domestic and industrial applications. Apparatus comprises a signal processor or processing module configured to receive signalling 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 signalling received.
EFFECT: saving energy for pump operation and reducing maintenance costs.
