967.696.00.0(03)

Setting the run-on time

When the hand is removed, the water flows for the

set time.

Settings:

• factory setting: 2s

• adjustment range: 0–10s (=0–10flash pulses)

1Cover IR sensor for approx. 2s until the

green LED flashes (1x).

✓ The washbasin tap is in the setting mode.

2Cover IR sensor for approx. 5–6s until the

red LED flashes (1x).

3To set the run-on time, cover the IR sensor

until the desired number of red LED flash

pulses is reached: 1flash pulse = 1second.

✓ The water flows while the IR sensor is

covered.

✓ When the IR sensor is released, the

green LED flashes (1x) and the water

stops. The tap is ready for operation

again.

Activating continuous flush

When the continuous flush is activated, the water

flows continuously for max. 10min.

Settings:

• Factory setting: 10 min

1Cover IR sensor for approx. 2s until the

green LED flashes (1x).

✓ The washbasin tap is in the setting mode.

2Cover IR sensor for 3s.

✓ When the IR sensor is released, the

water flows.

✓ The green LED flashes (1x).

The function can be terminated prematurely

by covering the IR sensor for approx. 2s.

Activating interval flush and setting

interval

A flush is released at the set interval (see "Setting

the flush time for the interval flush").

Settings:

• factory setting: 24 hours

• adjustment range: off, 12, 24, 48hours (= 1–4

flash pulses)

1Cover IR sensor for approx. 2seconds until

✓ The washbasin tap is in the setting mode.

2Cover IR sensor for approx. 25seconds until

the red LED flashes.

3Cover IR sensor until the desired number of

flash pulses is reached: 1 flash pulse = off,

2flash pulses = 12hours, 3flash pulses =

24hours, 4 flash pulses = 48hours.

✓ The green LED lights up 1x. The tap is

Setting the flush time for the interval

flush

The water flows for the set flush time when the

interval flush is activated.

Settings:

• factory setting: 5 seconds

• adjustment range: 5–200seconds (=1–40flash

pulses)

1Cover IR sensor for approx. 2seconds until

2Cover IR sensor for 3seconds.

✓ When the IR sensor is released, the

water flows.

3To set the new flush time, cover the IR

sensor until the desired number of red LED

flash pulses is reached: 1flash pulse =

5seconds.

✓ While the IR sensor is covered, the water

stops.

✓ After the IR sensor is released, the red

LED indicates the set flush time by

means of flash pulses: 1flash pulse =

5seconds.

✓ The green LED lights up 1x. The tap is

ready for operation again.

Restarting the control electronics

1Cover IR sensor for approx. 2seconds until

the green LED lights up 1x.

✓ The washbasin tap is in the setting mode.

2Cover IR sensor twice for approx.

0.5seconds.

✓ The red LED flashes.

3Cover IR sensor for approx. 5–10seconds

until the red LED lights up 4x.

4Remove hand from the detection range of

the IR sensor.

✓ The detection range is remeasured.

✓ After the measurement, the green LED

lights up 1x. The tap is ready for

operation again.

Setting the detection distance of the IR

sensor

The detection distance can be set in 5 levels.

Settings:

• factory setting: wall-mounted tap level5, deck-

mounted tap level4

• adjustment range: level 1 to 5 (=1–5flash pulses)

1Cover IR sensor for approx. 2seconds until

the green LED lights up 1x.

✓ The washbasin tap is in the setting mode.

2Cover IR sensor for approx. 0.5seconds

(2x).

✓ The red LED flashes.

3Cover IR sensor for approx. 15seconds until

the red LED flashes.

4Cover IR sensor until the desired number of

flash pulses is reached: 1 flash pulse = level

1, 2 flash pulses = level 2, etc.

5Remove hand from the detection range of

the IR sensor.

The flash pulses after 5 seconds can be

ignored.
