1. An electronic plumbing fixture fitting, comprising:
- a discharge outlet, the discharge outlet being operable to deliver water;
an electronic valve, the electronic valve being operable to permit flow of water through the discharge outlet when the electronic valve is activated and to not permit flow of water through the discharge outlet when the electronic valve is deactivated;
an activation sensor, the activation sensor being operable to activate and deactivate the electronic valve;
an actuation device, the actuation device being operable to activate and deactivate the electronic valve, the actuation device being operable to indicate a desired change to a parameter of water flowing through the discharge outlet; and
a parameter sensor, the parameter sensor being operable to detect the desired activation and deactivation of the electronic valve by the actuation device, the parameter sensor being operable to detect the desired change to the parameter of water flowing through the discharge outlet, the parameter sensor including an emitter and a detector;
wherein, when the activation sensor activates and deactivates the electronic valve, the electronic plumbing fixture fitting is in a sensor mode;
wherein, when the actuation device activates and deactivates the electronic valve, the electronic plumbing fixture fitting is in a manual mode;
wherein, in the sensor mode, energy is transmitted from the emitter at a first rate of transmission, and energy is detected by the detector at a first rate of detection;
wherein, in the manual mode, energy is transmitted from the emitter at a second rate of transmission, and energy is detected by the detector at a second rate of detection; and
wherein the first rate of transmission is less frequent than the second rate of transmission, and the first rate of detection is less frequent than the second rate of detection.
