CHECK CONTENTS
Separate all parts from the packaging and check each part with the pack
contents section. Pay attention to the variations of the different models.
Make sure all parts are accounted for before discarding any packaging
material.
If any parts are missing, do not attempt to install your electronic faucet until
you obtain the missing parts.

already installed in the dual power input box.
If your model is RONDA N DUO DP powered by battery: Connect the
other cable coming from the electronic unit at the product base to the
battery box.
If your model is RONDA N DP
powered by transformer, connect
the transformer to the transformer
socket in the dual power input box
and plug it into the electricity socket.
If your model is RONDA N DUO DP
powered by transformer, connect

hold the remote control straight in front of the sensor in a distance of about
6-8” (15-20cm). Choose the function you want to adjust by pressing once on
one of the function buttons. After pressing once on a specific function button, a
quick flashing of the LED at the front of the sensor will occur. At this stage, you
can change the setting by pressing the (+) or the (-) buttons, every push will
increase or decrease one level. After finishing the adjustment, turn the water

SETTINGS ADJUSTMENTSETTINGS ADJUSTMENT
DETECTION RANGE: This faucet was supplied with a self
adjusting sensor.The ideal detection range for the specific
location will be set automatically.
Only if necessary, use the remote control to adjust the sensor
range as follows:
Press the RANGE button. Wait until a quick flashing of the LED
in the sensor eye is perceived.Then, press + to increase the
range and – to reduce it. Every push will increase or decrease
one level.
Note: Once you have changed the detection range with the remote control,
the distance will be remembered by the sensor, even if the power source is
disconnected.To get back to the self adjustment mode, use the ADJ button only.
ENTRANCETOTHE SELF ADJUSTMENT MODE: Check that no
objects are in front of the sensor. Press the ADJ button. Once
a quick flashing of the LED of the sensor eye is perceived,
remove your hand holding the remote control and move away
from the sensor area.The ideal sensor range for the specific
location will be set automatically. Once the self adjustment has
taken place, the solenoid valve will be opened and closed for 1
second as an indication that the ideal sensor range was set and
the product is ready for use.
SECURITYTIME:The Security time, prevents continuous
running of water due to reflections or vandalism. By default,
if the sensor is covered for more than 90 seconds the water
flow will shut automatically.To resume regular operation any
obstruction must be removed.
Press the SEC button. Wait until a quick flashing of the LED
in the sensor eye is perceived.Then, press + to increase the
security time and – to reduce it.
DELAY INTIME: It is recommended to change the delay in
time for flush valves for urinals or toilets only.
If required, the delay in time can also be modified in faucets
as follows:
Press the IN button. Wait until a quick flashing of the LED in
the sensor eye is perceived.Then, press + to increase the
delay in time and – to reduce it.
DELAY OUTTIME:This button allows modifying the water
flow time after the user removes his hands from the
faucet. A delay out time close to 0 will save more water.
An increased delay out time will make the user experience
more comfortable.
If required, the delay out time can be modified as follows:
Press the OUT button. Wait until a quick flashing of the LED
in the sensor eye is perceived.Then, press + to increase the
delay out time and – to reduce it.
24 HOUR HYGIENE FLUSH:This model includes a 24 hours
hygiene flush which is disabled.To activate the hygiene flush,
press the clock button. Wait until a quick flashing of the LED
in the sensor eye is perceived.Then press + to activate the
hygiene flush.To disable it again, press – to deactivate it.
COMFORT FLUSH: If your model includes a Comfort flush
setting, it can be activated by pressing the flush button.
When the button is pressed, one blink of the LED in the
sensor eye is perceived.The pre-programmed flush cycle will
take place then.
The Comfort flush cannot be interrupted or deactivated by
pressing any button until it is over.
TEMPORARY OFF FUNCTION:This function is ideal to
perform any kind of activity in front of the sensor without
operating the system (for example, cleaning).
The faucet will remain shut for 1 minute when this button
is pressed once.To cancel this function and to return to
normal operation press the On/Off button again or wait 1
minute.
RESET BUTTON:This function restores all the factory
settings except for the sensor range. If required, press the
Reset button and without releasing it, press the + button
once.
NOTE: To enter the self adjusting mode, use the ADJ button.To change the
