To adjust features from default conguration, you must remove the
battery tray. Once battery tray is removed you will see the switches.
Default switch positions/modes are shown in bold.
Purge Features:
The purge switches can be congured for 4 modes of operation: Disabled (standard conguration), 12 hour, 24 hours, or 48 hours.
Purge water ow 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 congurations: 30 seconds (standard), 5s, 10s, 15s, 60s, & “Less Time-out”. The “Less Time-out” option
actually ceases water ow (turns o󰀨) 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 o󰀨 after hands are removed. If hands are not removed the time out delay will turn o󰀨 the faucet (ex:
standard conguration is 30 seconds).
Metering Mode:
When hands are detected by the sensor, water will run for ‘X’ seconds (standard conguration is 30 seconds) before turning o󰀨.
Sensor Sensitivity: (Default setting - Normal):
There are 4 sensitivity options, which can be selected to achieve the optimal detection performance related to the sink material, shape,
& nish. The faucet sensor sensitivity is congured during pack-out but the mode can be changed upon installation to optimize the
performance within the sink. Sensor sensitivity and sensor detection Modes A & B may be tried for various lighting conditions, sink
materials and shape.
Switch 7 controls the sensitivity
-On (default) is normal sensitivity for most sinks providing max range.
-O󰀨 sets 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 lters the e󰀨ects of owing in the bottom of problematic sinks. Detection maybe less for some
hands.
-O󰀨 disables the lter 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 conguration switch change has been made. Disconnect sensor cable from electronics box, wait 30 seconds, then
reconnect sensor cable.
All switches shown in
default mode.
