The complete solution for HCL in one device
Controller, push-button interface and occupancy detector are integrated into one device. Using the pre-programmed factory setting and the convenient B.E.G. smartphone app, the sensor is ready to use immediately, and can be configured in no time at all. The mechanical switches in the installation can be used via the three pushbutton inputs.

An economical solution for the DALI standard
Thanks to a large detection area and support for up to 64 DALI electronic ballasts, the detector is also suitable for large rooms, and is therefore a very economical solution for HCL with DALI lights which support “Tunable White” (Device Type 8) – see compatibility list.

A fully-featured occupancy detector
The occupancy detector provides occupancy-dependent daylight integration for energy saving and can control up to 4 DALI lighting groups e.g. training rooms, conference rooms or open plan offices. Its offset constant light regulation provides uniform lighting levels in rooms where the daylight falls from one side, thereby contributing to energy savings.

Flexible relay included
The built-in relay can be used to control non-DALI lighting for example. Alternatively, the
occupancy information can be forwarded to a BMS. Or, the relay can be used for a “cut-off” function, through which the DALI electronic ballasts are powered down when not being used. Depending on manufacturer, this saves between 0.2 and 1 watt per electronic ballast in standby losses.

Real-time biodynamic colour profiling
Different application profiles can be selected, e.g. for retirement homes, healthcare institutions and circadian lighting. The system runs autonomously thanks to its built-in real-time clock. But HCL can also be deactivated or pre-configured with a customer-specific profile.

World first – Pure Colour
Instead of simulating changes in daylight through the day, an optional external daylight sensor detects the actual daylight colour temperature and uses this information to control
the HCL. This has the advantage of exactly replicating actual daylight colour temperature.

Orientation light
The “orientation light” function can be activated, and operates after the follow-up time previously
configured. It limits the maximum output level of connected lights to an adjustable value. This means that areas with a safety requirement are not completely dark, but energy is still saved compared to full illumination.

Simple to extend
Up to 4 additional slave units can easily be connected via the DALI bus, enabling economical extension of the detection area.
