Programme table

The infrared electronics provide seven preset programmes for selection.
Programme
1
Temporary shutoff*
2
Automatic flushing*
Flush interval
Usage-dependent
Usage-independent
Detection zone
3
Pre-flushing*
4
Intermediate flushing*
1
* Cleaning mode can be activated when temporary shutoff is activated. In cleaning mode, flushing is not triggered
for 3 minutes, even if an object is detected.
2
* Automatic flushing serves to ensure water hygiene in the event of long-term non-utilisation of the fitting. Flushing is initiated
after 24 hours (usage-independent) or 24 hours/72 hours after the fitting was last used (usage-dependent).
3
* When pre-flushing is active, a flow volume of 3 litres is flushed 2 seconds after an object is detected.
4
* When intermediate flushing is active, flushing is initiated every 60 minutes if an object is continuously detected (max. 3x).
Fault/cause/remedy

Remedy
- Perform calibration again, ensuring there is no
obstacle in the adjustment range of the servo
motor
- Replace servo motor
- Open isolating valve in cistern
- Switch on power supply or replace transformer
- Replace electronics
- Replace servo motor
- Attach plug-in connector
- Increase detection zone using remote control
(special accessories 36 206)
- Connect or check pneumatic hose
- Terminate cleaning mode prematurely or wait 3
minutes
- Maintain or replace waste, see technical
product information for cistern
- Calibrate servo motor
- An opposing object is detected. Reduce
detection zone using remote control
(special accessories 36 206)
- Replace or calibrate servo motor
- Push residual flow slider at waste downwards
- Turn float of filler valve upwards
