After the group with 9 flashing signals, the routine starts
from the beginning.
5. Selecting the flow volume:
The flow volume is selected by releasing the button in the
pause after a group of flashing signals. The fitting flushes
immediately with the selected flow volume (the
corresponding flashing signals are displayed again during
flushing).
6. The flow volume can be changed within 20 seconds of
flushing (if necessary) by pressing the button again. The
selected flush setting is stored if the button is not pressed
again within 20 seconds of flushing.
Control reverts to normal mode.
Make settings with infrared remote control, see fold-out
page IV, Figs. [27] - [28].
Maintenance
• Shut off water supply
• Switch off voltage supply
• Inspect and clean all components and replace if necessary
Replacing the switched-mode power supply, see fold-out
page IV, Fig. [29]
Replacing the servo motor
1. Disassemble plate, see fold-out page IV, Fig. [27].
2. Disconnect plug-in connectors, see Fig. [30].
3. Disassemble servo motor, see Fig. [31a] or [31b].
4. Calibrate new servo motor, see
Calibrating the servo
motor .
5. Install new servo motor, see fold-out page III,
Figs. [20a] or [20b] - [21].
6. Install wall plate, see fold-out page III, Fig. [26].
Replacing the electronics
1. Disassemble plate, see fold-out page IV, Fig. [27].
2. Disconnect plug-in connectors, see Fig. [30].
3. Disassemble servo motor, see Fig. [31a] or [31b].
4. Replace electronic module, see Fig. [32].
5. Calibrate servo motor, see
Calibrating the servo motor .
6. Install servo motor, see fold-out page III,
Figs. [20a] or [20b] - [21].
7. Install wall plate, see fold-out page III, Fig. [26].
Calibrating the servo motor
Caution : The servo motor must be calibrated outside the
cistern.
1. Connect voltage supply, see fold-out page IV, Fig. [33].
The servo motor must not be connected when
performing this operation.
The indicator lamp in the electronics begins to flash.
2. Connect servo motor to electronic module, see Fig. [34].
The indicator lamp in the electronics stops flashing and
adjustment automatically starts. The servo motor moves to
the adjustment positions.
3. Disconnect plug-in connectors, see Fig. [35].
Replacement parts , see fold-out page I (* = special
accessories).
Care
For directions on the care of this fitting, please refer to the
accompanying Care Instructions.
Fault/ cause/ remedy
Fault Cause Remedy
Indicator lamp in the electronics
flashing continuously after
calibration • Calibration is incorrect
• Obstacle during calibration - Perform calibration again, ensuring there
is no obstacle in the adjustment range of
the servo motor
• Servo motor defective - Replace servo motor
No flushing after pressing the
button • Electronics defective - Replace electronics
• Water supply interrupted - Open isolating valve in cistern
• Servo motor defective (no rotation) - Replace servo motor
• Plug-in connector without contact - Attach plug-in connector
• No voltage (indicator lamp on back of
electronics not flashing)
- Switch on power supply
• switched-mode power supply defective - Replace switched-mode power supply
Water flowing continuously • Outlet valve not closing - Outlet valve defective (repair, replace,
observe replacement part), see cistern
instructions
- Calibrating the servo motor
Flow volume too low • Servo motor defective or not calibrated
(incomplete rotation)
- Replace or calibrate servo motor
• Residual flow rate too high - Push residual flow slider downwards
• Flow rate in cistern too low - Turn float of filler valve further upwards
