ABSTRACT:
An electro-mechanical mixing faucet for proportionally mixing hot and cold water in accordance with a user-selected mix ratio. A user-adjustable temperature selector produces a mix signal which adjusts hot and cold water valves to permit flow in amounts which will produce the desired temperature. The temperature selector includes a bank of LED's for indicating the selected temperature. When a user actuates the temperature selector, the LED's turn on brightly to indicate the selected temperature and also the water is immediately turned on. Following use of the faucet, the temperature selection is returned to a neutral temperature after a dormant period. An LED flashes when all hot water is demanded.
