STEP 9. SETTING THE CONTROLLER
(If adjustments are required. Note factory defaults for program shown in Quick Reference Chart.)
Press the Enter/Exit button on the controller to turn on the LCD screen. The first screen you will see is the visual battery
strength indicator (Fig. 11). After 5 seconds, this will default back to the Main Menu screen, where the following features
can be found. Starting with the top feature:

BATTERY STRENGTH INDICATOR

Displays the current state of the batteries. The visual battery icon will appear "full" when batteries are still
healthy. As the batteries drain, the battery icon will appear more and more depleted. The word next to the
battery icon will give a quick synopsis of the battery strength (i.e. Healthy, Average, Poor Health). When the
batteries have depleted to a point where they no longer can operate the solenoid, the battery strength indicator
will read "REPLACE!" At this time, the controller will beep every time an object is sensed, but will not operate
the solenoid. Replace the batteries immediately when this happens.
RUN-ON TIME
Water flow stops at the selected run-on time after the user removes hands from the sensing zone. Run-on
selection times are 0 to 8 seconds or 1 to 8 minutes for scrub-up applications. Run time is factory set to 0
seconds. Note: If the user activates the faucet before the run time expires, the faucet will continue to operate
and reset when their hands are removed again.

RESPONSE TIME

Response time is the amount of response time it takes for the sensor to react to hands placed in the sensing
zone. The factory default is 4 pulses per second (Standard). This can be decreased to 2 pulses per second
(Slow) to save battery life or increased to 8 pulses per second (Fast) for maximum response. Note: Using 8
pulses per second will significantly reduce battery life. This feature is most beneficial when the controller is
hardwired.
BLOCK TIME (1-8 SECONDS)
The blocking time is the amount of time required between uses. This prevents the faucet from activating again
until the blocking time has expired. The default value is 1 second. The blocking time moves up in 1-second
increments, up to 8 seconds max.
SENSE RANGE (3" - 15")
The sensor range is the maximum distance at which the user is detected. The sensor range includes 3", 6",
8", 10", 12" and 15". The gooseneck product default value is 10". Note: Sensor ranges +1" subject to environ-
mental conditions.

METERING MODE

A
This allows for a continuous flow for a set amount of time, regardless of how long an object is placed in front of
the sensor. Metered program is selectable from 7 to 240 seconds (when enabled) of continuous operation. It
is factory set to Disabled.

ADDITIONAL FEATURES

Buzzer: Allows the user to turn ON or OFF the audible buzzer. Factory set to ON.
Language: Allows the user to set their desired language of the controller; either English or French. Factory set to English.
Diagnostics: Controller logs and displays Average usage per day, as well as Average Time-On of the faucet and Total
Faucet Activations to Date.
Set Defaults: This option is found in the Diagnostics Menu. Selecting this feature resets all previously altered settings (i.e.,
Sense Time, Run-On Time) and sets them back to their initial default value.
Self-Test: Used to help troubleshoot the electronics. It helps test out the features of your electronic faucet - like the
solenoid, sensor, 3-position switch feature and more.
