<p>Technologies for use with a hot water recirculation system (200) containing a hot water source (120), a flow sensor (108) downstream from the source, a booster pump (110) downstream from the sensor, and a plumbing fixture (122) downstream from the pump are provided. The technologies enable a controller (112) 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.</p> |
