Abstract:
1. An electronic plumbing fixture fitting, comprising: a discharge outlet operable to deliver water; an electronic valve, the electronic valve operable to permit flow of water through the discharge outlet when the electronic valve is open and not permit flow of water through the discharge outlet when the electronic valve is closed; a first sensor, the first sensor having a rank in a sensor hierarchy, the first sensor having a first zone for hands-free operation of the electronic valve, the first sensor operable to open the electronic valve when an object enters the first zone and close the electronic valve when the object does one of: (i) exit and reenter the first zone, and (ii) exit the first zone; and a second sensor, the second sensor having another rank in the sensor hierarchy, the second sensor having a second zone for hands-free operation of the electronic valve, the second sensor operable to open the electronic valve when an object enters the second zone and close the electronic valve when the object does one of: (i) exit and reenter the second zone, and (ii) exit the second zone; wherein, during operation of the fitting, the first sensor and the second sensor are both operable at a given time; wherein, during operation of the fitting, the sensor hierarchy governs the operation of the first sensor and the second sensor at the given time; wherein the first sensor ranks higher in the sensor hierarchy than the second sensor; wherein the second sensor is inoperable to close the electronic valve while the electronic valve is open based on a triggering of the first sensor; and wherein the first sensor is operable to close the electronic valve while the electronic valve is open based on a triggering of the second sensor.
