2.3.3 Operating mode
Infrared actuation
Product information
Flush actuation takes place without contact via an infrared sensor on
the flush plate.
The flush volume can be set in four stages.
In order to actuate a flush, a person must be within the detection area of
the infrared sensor for at least 8 seconds.
If a person leaves the detection area, a flush is automatically actuated.
Depending on the setting, the flush duration is between 2 and 15 sec‐
onds.
A flush cycle can also be manually actuated by placing a hand briefly in
front of the sensor.
