Adjustable modes and features selection:
To adjust features from default configuration, you must remove the
battery tray. Once battery tray is removed you will see the switches.
Purge Features:
The purge switches can be configured for 4 modes of operation: Disabled (standard configuration), 12 hour, 24 hours, or 48 hours.
Purge water flow duration is 2 minutes. Note: Purge activation occurs every switch selected time (0,12, 24, or 48 hours) after last
activation.
Flow Time:
There are 6 optional time configurations: 30 seconds (standard), 5s, 10s, 15s, 60s, & “Less Time-out”. The “Less Time-out” option
actually ceases water flow (turns off) after 20 minutes to limit chance of water damage in the event a sink drain becomes blocked .
Sensing Mode (DEFAULT):
During this mode the valve will shut off after hands are removed. If hands are not removed the time out delay will turn off the faucet (ex:
standard configuration is 30 seconds) (See Switch Position Diagram shown above)
Metering Mode:
When hands are detected by the sensor, water will run for ‘ X’ seconds (standard configuration is 30 seconds) before turning off. (See
Switch Position Diagram shown above)
Sensor Sensitivity:
(Default setting: Low):
The 4 sensor sensitivity options are used for varied sink and environmental conditions. The factory default setting should be ideal
for most general applications. However, sensor performance can be optimized to adjust for unusual sink finish, material, shape, or
unusually bright or dark lighting conditions.
Switch 7 controls the sensitivity
-On (default) is normal sensitivity for most sinks providing max range.
-Off set the sensor to a lower sensitivity level for sinks that cause false activation. The detection range maybe less for all hands.
Switch 8 controls sensor mode
-On (default) enables the mode that filters the effects of flowing in the bottom of problematic sinks. Detection maybe less for some
hands.
-Off disable the filter mode, so detection is expanded deeper into the sink for max detection range for all hands. Some sinks may
only be able to operate in this mode.
NOTE: After a configuration switch change has been made, disconnect sensor cable from electronics box, wait 30 seconds, then
reconnect sensor cable and wait 30 seconds to allow the sensor to tune-in the sink characteristics.
All switches shown in default mode.
