<p>A household electronic mixing-valve faucet including a faucet body having hot and cold water inlets, and an outlet; a controller; powered valves responsive to the controller; an arrangement adapted to determine an extent of opening of each valve; temperature sensors and pressure sensors disposed upstream of the valves; and a third pressure sensor disposed downstream with respect to the valves; the controller adapted to receive: extent of opening information, from the arrangement, and temperature and pressure information from the sensors, the controller having calibrated relationships relating (i) a flowrate of hot water flowing through a hot water flowpath, to the extent of opening of the powered valve thereof, as a function of a first pressure differential, and (ii) a flowrate of cold water flowing through a cold water flowpath, to the extent of opening of the powered valve thereof, as a function of a second pressure differential, and wherein, during operation, the controller controls the powered valves based upon the temperature information and upon actual pressure differentials within faucet flowpaths.</p> |
