BT Control System

Super flexible lighting control with app control via Bluetooth

Easy commissioning with plug-and-play, convenient configuration, operation and control via smartphone with our free app: With versatile control solutions for DALI LED drivers, you can install professional light management as simply and conveniently as never before.

With the three control units DALI ACU BT, DALI ECO BT and DALI ECO BT RTC, you have all the options you need to efficiently and economically realize lighting systems in rooms with up to 32 luminaires under 100 m²: medium-sized offices, small conference rooms, stairwells and foyers or corridors.

While DALI ACU BT is installed in flush-mounted boxes behind a classic push-button, DALI ECO BT is suitable for luminaire installation or with a strain relief for independent installation, e.g. in suspended ceilings. DALI ECO BT RTC additionally offers you an integrated real-time clock (RTC). This creates the basis for daytime-dependent control and thus for the development of human-centric lighting concepts for simulating the course of daylight in color temperature and brightness.
