LIGHTING CONTROLS

differs massively from the zone further away. The two zones are, therefore, each allocated to a different light channel of the DUO DALI (Fig. 1). To enable both light channels to be controlled through the offset, an adjustment must be made using the remote control or the ESY-App (Fig. 2). This requires a fixed offset between channel 2, the zone away from the windows, and channel 1, the window side. The optimal size of the offset depends on the actual room situation, but in many cases, it is 30 %, as used here as an example. Control any time of the day As the daylight entering the classroom increases during the morning, the detector initially dims only the lights near the window. The zone away still needs 100% light output. When the light output from the lights near the window falls to 70%, an offset of 30% has been reached (Fig. 3). The detector then starts to dim the lights away from the window.
Fig. 2: The optimal value of the offset between channel 2 and channel 1 is very often 30%. The value can be adjusted easily using the ESY-App interface.

Fig. 1: As this planning example shows, lights further away from windows and those nearer to the windows in a classroom are each assigned to a different light channel of the DUO DALI.
