FIELD: heat engineering.
SUBSTANCE: group of inventions concerns a method for operating a circulation pump with a variable speed, in particular, in a heating system. A system for controlling the pump in the method for operating at least sensory determines a physical operational parameter of the pump and directly or indirectly compares it with at least one saved control value to evaluate this option of installing the pump. The control value or values is depended on the current operational point of the pump, and in the system for controlling the pump, individual control values corresponding to a set of operational points are saved. The system for controlling the pump, depending on the current operational point, uses an appropriate control value for synchronization with the measured value.
EFFECT: inventions are aimed at automatic detection of an unfavorable option of installation inside the heating system leading to increased noise emission.
