Adjust the brightness 

Motion detector is combined with a dimming insert. 
With the IR remote control, alternatively via the 2-wire extension, the light can be dimmed 
temporarily. The next time the light is switched on, it is switched on again to the switch-on 
brightness 
Light is switched on. 

Press 

¿

 button or 2-wire extension above for longer than 0.4 seconds. 

The light gets brighter up to maximum brightness. 

Press 

Á

 button or 2-wire extension below for longer than 0.4 seconds. 

Light gets darker to minimum brightness. 

An installation button cannot be used to adjust the brightness. 

Switching the light on with minimum brightness 

Motion detector is combined with a dimming insert. 
Light is off. 

Press 

Á

 button or 2-wire extension below for longer than 0.4 seconds. 

The light is switched on with minimum brightness for the duration of the run-on time. 

An installation button cannot be used to switch on to minimum brightness. 

If the 

¿

 button or 2-wire extension above is pressed for longer than 0.4 seconds, the 

light is switched on to minimum brightness and then brighter. 

Save switch-on brightness 

Motion detector is combined with a dimming insert. 

Set light to the required brightness. 

Press 

Å

 button or 2-wire extension insert over entire surface for longer than 

3 seconds. 
Switch-on brightness is saved. For confirmation, the light is switched off briefly and 
switched on again. 

In the state as supplied the  maximum switch-on brightness is saved. 

An installation button cannot be used to save the switch-on brightness. 

Switching on presence simulation 

Press the 

Ä

 button for longer than 10 seconds. 

Presence simulation is switched on. 

This function is not adjustable in pulse operation. 

By pressing the 

À

 button the automatic operation is switched on again. 

Setting the sensitivity 

Press 

25 %

50 %

75 %

 or 

100 %

 button for longer than 10 seconds. 

Sensitivity is set. 

Limiting the detection area 

The detection area of the motion detector can be limited by switching off a sensor. Both sensors 
cannot be switched off at the same time. Since the detection areas of both sensors overlap, 
there is no distinct demarcation of the blocked out detection area. 

Press 

Æ

 or 

È

 button for longer than 10 seconds. 

Detection area is limited. 

Using the 

Ç

 button, both sensors are switched on again. 

Setting brightness threshold 

One of four predefined brightness thresholds (see table on adjustable buttons) or one individual 
brightness threshold can be set (see Saving ambient brightness as brightness threshold). 

Press 

Ê
