Setting: Usage Duration
Default: 5 seconds.
The sensor will sense urinal usage for a pre-
determined duration before sending a signal to the
flush valve. This duration can be changed if required.
Duration:
The (Default) short duration (5 seconds) should
be sufficient for most installations and can be
specified if a small amount of urine is required to
activate the valve.
A medium duration (7 seconds) can be selected
to minimise accidental flushes.
A long duration (9 seconds) can be selected in
sub optimal environmental conditions such as
small rooms without ventilation or poor drainage.
•Press and hold button for 1 second to CYCLE
through the Sensor Duration settings.
•The indicator LED will flash to confirm the current
Duration setting.
Short Duration (5 seconds): 1 Flash
Default Duration (7 seconds): 2 Flashes
Long Duration (9 seconds): 3 Flashes
Setting: Stadium Mode
Default: ENABLED.
To conserve water in HIGH FREQUENCY usage
environments (i.e.: 5 uses in less than 60 seconds),
the product will automatically switch to water
conserving “Stadium Mode”.
When in the unit has entered Stadium Mode, it will activate
a flush at regular intervals of 180 seconds, regardless of
the number of uses it receives during this period.
If there is no further use within a period of 180 seconds,
the unit will automatically switch back to its Default
operation.
•Press and HOLD button for 5 seconds to set
the STATUS of Stadium Mode.
