Patent ID: 7946504

Claim:
An electronic faucet for mixing a hot fluid and a cold fluid to a settable temperature and flow rate, the faucet comprising; a mixing body within said hot fluid and said cold fluid are mixed, said body comprising an inlet for the hot fluid and an inlet for the cold fluid, and an outlet from which the mixed fluids are discharged therefrom; at least one mixing valve at said mixing body to control the ratio of said hot and cold fluids; a temperature sensor for sensing the temperature of said mixed fluids and outputting a signal corresponding to said temperature; an electronic control system which receives said signal of said fluid temperature sensor for controlling said at least one mixing valve to adjust the ratio of the hot and cold fluids; an interface for programming said electronic control system to allow setting of at least one of the temperature and the flow rate of the mixed fluids; and at least one motor for adjusting at least one of the ratio of the hot and cold fluids received by the mixing body and the flow rate of the mixed fluids discharged from the mixing body; wherein the faucet further comprises a manual override system comprising a handle or pair of handles operably connected to said electronic control system and adapted to override said electronic control system whereby the faucet is manually controllable by said handle or pair of handles and the mechanism to disable the electronic control system comprises at least one or driver operably connected to said electronic control system and the at least one motor, the motor driver adapted to detect an out of tolerance situation regarding a parameter of the motor(s) and detecting said out of tolerance situation, it disables the electronic control system.
