Abstract

See full text

Technologies for use with a hot water recirculation system containing a hot water source, a flow sensor downstream from the source, a booster pump downstream from the sensor, and a plumbing fixture downstream from the pump are provided. The technologies enable a controller to couple to the sensor and the pump, and operate in a calibration mode and a control mode. Such operations can increase energy efficiency of the pump and increase operational longevity of the pump.
