Direct WC flush kit by sensor sensibility

Wall mounted electronic WC flush trigger kit, for a direct flush

Flush is triggered once the user leaves, after the sensor detects users presence or voluntarily approaching hands near the sensor.

Vandal-proof

DOUBLE FLUSH VOLUME: the sensor determines if the direct flush needs to be compete or reduced depending on the distance and the presence period. = half-flush for less than one minute and complete flush for more that one minute.
