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.

ENTRANCE TO THE 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. 

SECURITY TIME: 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 IN TIME: 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 OUT TIME: 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 sensor 

range, use the RANGE button.
