Abstract: A circulation pump for supplying hot water to a hot water inlet of a temperature-controlled bypass valve for domestic hot-water recirculation, the circulation pump including a pump controller configured for controlling a pump motor such that the pump motor cycles between on-phases and off-phases, the circulation pump further including a sensor for measuring at least one operation parameter of the circulation pump; the pump controller being configured such that an on-phase is terminated and an off-phase is initiated when an output signal of the sensor indicates that said at least one operation parameter reaches a termination threshold value or range.
