ABSTRACT:
An automatic temperature regulating system for a faucet, especially an automatic faucet in which water flow is activated by a touchless switch, is constructed to operate so as to compensate for lag time of hot water arriving from the hot water supply. The apparatus includes at least one temperature sensor, this first sensor being disposed in the hot water supply line upstream of the hot water valve. A more sophisticated apparatus includes a second-temperature sensor disposed for sensing the temperature of the outlet water. Methods of automatically regulating temperature of output water from a remote-activated or touchless-switch-activated outlet to compensate for lag in arrival of hot water from the hot water source, are also described.
