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 ex- treme light ratios. If the detector is fitted near lights with a high proportion of indi- rect 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 learning button of the device to the window, if possible. With increasing mounting height the sensitivity of the brightness measuring is reduced. Especially at mounting height > 3.0m a test application on site is recom- mended.
