Abstract
A variable temperature electronic faucet water supply system provides a plurality of preset water temperature settings from which the user may select a desired water temperature by pressing a temperature selection button. If no water temperature is selected by the user, the faucet automatically delivers water at a default temperature setting. The faucet water supply system includes a motion detector mounted in the head of the faucet which will detect motion near the faucet head. The water is delivered from the faucet head at the preselected temperature when motion is detected near the faucet head. Water is delivered at the preselected temperature for up to two seconds after motion is last detected near the faucet.
