Making settings

Setting mode
Setting mode has the following functions:
- Changing the flow volume
- Querying and changing the programme
- Checking the detection zone
The indicator lamp in the sensor system illuminates in setting
mode when the detection zone of the fitting is reached by an
approaching user. Flushing is immediately triggered when the
detection zone is exited again. The minimum delay is not
available in setting mode.
Activating setting mode
Disconnect the power supply to the electronics and reconnect
after 5 s.
• The plug connection between the servo motor and the
electronics must not be detached.
• Setting mode is automatically terminated after 3 minutes.
