1. A touchless, temperature control faucet including:

  • at least one fluid outlet assembly from which the fluid emerges;

    at least one fluid control valve which allows variable control of the temperature of the emerging fluid based on temperature feedback by a temperature signal from a temperature sensor arranged downstream of the fluid control valve;

    at least one touchless control user interface adapted to receive touchless control instructions from a user, wherein the touchless control instructions varies the temperature of the emerging fluid;

    at least three touchless sensors mounted on said fluid outlet assembly, each said sensor adapted to sense an object in a respective sensing field;

    wherein at least one of said touchless sensors enables the switching on and off of the emerging fluid;

    wherein at least one other of said touchless sensors enables the temperature of said emerging fluid to increase;

    wherein at least one other of said touchless sensors enables the temperature of said emerging fluid to decrease.
