ABSTRACT:
A water faucet assembly providing touchless water temperature and water flow adjustment. The assembly comprises a spout, a water mixing valve, at least one proximity sensor, and a microcomputer. The water mixing valve provides a mix and controls the flow of hot water from a hot water supply and cold water from a cold water supply to the spout. The at least one proximity sensor provides a water temperature or water flow input signal having a value corresponding to the distance of an object from the sensor. The microcomputer is responsive to the value of the water temperature input signal to control the water mixing valve and generate a mixture of the hot and cold water corresponding to the distance of the object from the proximity sensor. The microcomputer is also responsive to the value of the water flow input signal to provide a flow of water from the spout corresponding to the distance of the object from the proximity sensor.
