LIGHTING CONTROLS
Fig. 4: The double offset of the APC presence detectors extends the scope for design and further improves overall energy efficiency.
Once the daylight is sufficient in both zones, it switches all the lights off. If it gets darker outside again, this sequence is reversed. The offset improves energy efficiency through the earlier reduction or delayed increase in light output from the lights near
the window as the daylight fades or brightens. Double offset of the APC presence detector According to Core Distribution, the DUO DALI with offset variant and simple
2-channel broadcast mode has been one of the most popular ESYLUX products with customers over the years. For a more flexible form of light control, an alternative solution is the APC presence detector for the updated DALI-2 standard, which can control up to 16
Fig. 5: To adjust the lighting in a room to the incidental daylight even more efficiently, APC presence detectors make it possible to add more groups with an offset.
“This double offset creates greater flexibility for the design process and further increases energy savings.”
