HOW THE ELECTRONIC UNIT OPERATES (fig. F)
• The YELLOW LED l (IN-12Vac) is lit when the power supply is operating.
• The GREEN LED m (EV) is lit when the detector senses hands in the detection zone and the solenoid
valve opens the water flow. When the hands are removed (Standard mode) or the hands are passed
in front of the sensor for a 2
• The RED LED k (SECUR) is lit and the flow of water stops. In the Standard mode, if the detector senses hands
(or any other object) continuously for 45 seconds the anti-blocking safety is activated. In the ON/OFF mode,
the anti-blocking security is activated after 30 minutes of continuous flow.
Once the hands or object are/is removed the system is reset and a new cycle can commence.
For the mode options see the ADJUSTMENT Section.
• For the electronic unit to operate correctly the ambient temperature should be between 5°C and 40°C.
ADJUSTMENT (fig. E)
• The detection distance can be adjusted from 8 to 25cm using the potentiometer "GAIN" f
located on the electronic unit.
• The automatic shut-off delay can be adjusted up to 12 seconds using the potentiometer "TEMPO" i
located on the electronic unit.
• We do not recommend setting the potentiometers in their minimum or maximum position.
Operating Modes
• STANDARD MODE: "PROG" j in the position 0: automatic shut-of
(pre-set in this mode at the factory).
- Water flows when the hands are passed in front of the sensor.
- Water stops flowing when the hands are removed, with an adjustable shut-off delay from 2 - 12 seconds.
• ON/OFF MODE: "PROG" j in the position 1: voluntary opening and closure of the valve.
- Water flows when the hands are passed in front of the sensor.
- Water stops flowing when hands are passed in front of the sensor for a 2nd time.
- Anti-blocking security after 30 minutes' flow.
• For other operating Mode options please contact Technical Services (contact details below).
ADJUSTING THE FLOW RATE (fig. I) - except 20164 models
• The flow rate is pre-set at the factory at 3 lpm (at 3 bar).
• The flow rate can be adjusted directly on the flow straightener using a 2.5 mm Allen key:
- Notch n°1 = 3 lpm (at 3 bar).
- Notch n°2 = 4 lpm (at 3 bar).
- Notch n°3 = 5 lpm (at 3 bar).
TEMPERATURE LIMITATION (mixers)
For the UK and Ireland we recommend installing an appropriate, approved thermostatic mixing valve
(TMV) to provide safe, anti-scald hot water.
Where thermostatic mixing valves are installed the temperature limiter MUST BE REMOVED
from all point-of-use mixers. Recommended maximum temperature settings for are: bidets 38°C,
washbasins and showers 41°C. For all other countries please refer to the relevant hot water safety guidelines.
Standard side temperature selector (fig. J)
The product is delivered with the maximum temperature limiter engaged. To override it:
• Isolate the water supply.
• Loosen the grub screw at the back of the mixer body using a 4mm Allen key and remove the temperature
selector.
• Prise the coloured limiter n upwards with a flatheaded screwdriver to remove.
• Re-assemble and commission in line with the TMV manufacturer's instructions.
• When used with a TMV, always carry out a cold water failsafe check.
time (ON/OFF mode), the flow stops and the GREEN LED goes out.
