What are "Ambient lighting channels"?
Unused LED channels can be used to provide additional staircase lighting (e.g. for a 10-step staircase, channels 11 to - depending on the controller - 14/16/20 are free for use). These channels are permanently on low dim, but illuminate when the sensor is triggered. Perfect for LED strips in handrails or additional ceiling spotlights.
An optional daylight sensor deactivates the ambient lighting channels, providing further energy savings.
