Functionalities

The installation includes five zones with the option of two or three daylight zones and one or two no daylight controlled zones, e.g. board lighting, desk lighting, etc.

All luminaires in the daylight zones and board lighting are equipped with DALI drivers designed for dimming. Luminaires for desk lighting (zone 5) are equipped with standard no dimmable drivers.

The desk lighting is controlled with a switch. If the switch is on and someone enters the room, the lighting is switched on automatically. Daylight control can be overridden using either a push-button or via the DALI-2 interface.
