Installing transformer and electronic module
1. Fit sheet with transformer (F) and electronic module (A) in
wall mounting box, see Fig. [9].
2. Connect plug-in connector between electronic module (A)
and solenoid valve (E), see Fig. [10].
3. Connect sensor cable (B1) to connecting cable of electronic
module (A).
4. Connect transformer (F) to electronic module (A).
5. Connect 230V connecting cable (G) with transformer
cable (F1), see Fig. [11].
6. Switch on voltage supply.
7. Position detection is started:
- The display alternately indicates P and E.
- The system initiates flushing 3 times for approx. 1 s and
checks whether water is flowing in the detection zone.
8. After detection of the position, a main flush is carried out.
Setting mode is activated.
When the settings are correct, fit the inspection cover.
Making settings
Setting mode
In setting mode, the flow volume, see Setting the flow volume
and detection zone, see Setting the range can be checked and
modified. The counter can also be reset, see Resetting
counter.
Position detection is limited to 25 voltage interrupts in the
electronics module. After the 26th voltage interrupt, position
detection is no longer performed.
For position detection to be reactivated, the counter must
be reset, see Resetting counter
It is also possible to set the flow volume and detection zone
via the optional remote control.
Setting mode is activated as follows:
1. Remove the inspection cover.
2. Disconnect the power supply to the electronic module (A)
and reconnect after 10 s, see Fig. [12].
3. Position detection is started:
- The display alternately indicates P and E.
- The system initiates flushing 3 times for approx. 1 s.
4. After detection of the position, a main flush is carried out.
The indicator lamp (A4) in the electronic module (A) flashes,
setting mode is activated, see fold-out page III, see Fig. [13].
Setting mode is automatically terminated after 3 min if no
setting is made.
5. Press on the flashing indicator lamp (A4) in the electronic
module. The indicator lamp (A1) in the display (A2) of the
electronic module illuminates.
6. Press again on the flashing indicator lamp (A4) in the
electronic module.
Flow volume setting mode is activated. The display (A2)
runs from top to bottom for 5 times.
During this time, it is possible to switch to the range setting
mode by pressing the flashing indicator lamp (A4) again.
In the range setting mode the display (A2) runs from right
to left for 5 times. It is now again possible to switch to the
other mode.
Following 5 times without a mode change, either the flow
volume set or the range set is displayed, depending on the
activated setting mode.

Setting the flow volume
The factory-set flow volume is approx. 3 l at a flow pressure
of 3 bar.
The flow volume can be changed as follows:
1. Select flow volume setting mode.
2. The flow volume can be increased by pressing on the
flashing indicator lamp (A4), see Fig. [13].
After the flow volume of 7 l, the volume returns to 1 l again.
3. The flow volume displayed is saved if no change is made
within 10 s.
One flush is performed at the set flow volume. The display
extinguishes, and the setting mode is terminated.
Setting the range
The range can be changed in steps. The factory-adjusted
range is step 5.
The range can be changed as follows:
1. Select range setting mode.
2. The range can be increased in 9 steps (1 – 9) by pressing
on the flashing indicator lamp (A4), see Fig. [13].
Step 9 is followed by P (for performing counter reset).
After P, step 1 is returned to.
3. The range displayed is saved if no change is made
within 10 s.
The display extinguishes, and the setting mode
is terminated.
Resetting counter
1. Select range setting mode.
2. Press on the flashing indicator lamp (A4) until the display
indicates P, see Fig. [13].
3. The counter is zeroed if no change is made within 10 s.
The display extinguishes, and the setting mode is
terminated.
Maintenance
Inspect and clean all components and replace if necessary.
Shut off water supply!
Remove the inspection cover.
I. Solenoid valve and filter
1. Disconnect plug-in connector between solenoid valve (E)
and electronic module (A), see Fig. [15].
2. Close isolating valve (H), see Fig. [2].
3. Remove solenoid valve (E) with seals (E1).
4. Remove filter (E2), see Fig. [14].
5. Replace solenoid valve if necessary.
Assemble in reverse order.
Note flow direction of solenoid valve.
Important: install solenoid valve in flow direction.
II. Transformer
Switch off voltage supply!
1. Disconnect plug-in connector between transformer (F) and
electronic module (A), see Fig. [12].
2. Detach upper part of transformer (F) from base.
Assemble in reverse order.
After reconnecting power supply, position detection begins.
