Notes
Safety
DANGER
· The device must be mounted and commissioned by an authorized electrician.

· The device must not be opened.
· For planning and construction of electric installations, the relevant guidelines, regulations and
standards of the respective country are to be considered.
Mounting
à Brightness measurement in particular
The daylight measurement determines an average brightness value in the room, which can differ from
the brightness on the worktop. You should therefore avoid mounting sites with extreme light ratios.
If the detector is fitted near lights with a high proportion of indirect light, the artificial light level at the
detector mounting point must not exceed the wanted nominal lighting level in the room. This can be
compensated by increasing the separation between the light cone and the detector. For constant lighting
control, direct artificial light on the detector should be avoided.
It is recommended to orientate the programming button of the device to the window, if possible. With
increasing mounting height the sensitivity of the brightness measuring is reduced.
