Abstract
A circulation pump assembly (22) includes an electrical drive motor (10) and an electronic control device (12) controlling the drive motor (10). The control device (12) is configured for the speed control of the drive motor (10) according to a control schema (I, II, III). The control device (12) includes a detection function (42) which is configured to detect a condition variable representing an operating condition, from a parallel flow path (16, 18, 20) with a second circulation pump assembly (22). The control device (12) is also configured such that it can change the control schema (I, II, III) on the basis of a condition variable detected by the detection function (42). Further an arrangement of at least two such circulation pump assemblies (22) and a method for the control of such two circulation pump assemblies (22) are provided.
