The "Colour temperature control” function is a 1/2 push-button function in which 2 push-buttons are configured and connected completely separately, one push-button being assigned the "1/2 button dimming On/brighter, warm/warmer” function and the other the "1/2 button dimming Off/darker, cold/colder” function.

The prerequisite for this function is that the "Single” option is selected in the device settings for the channel concerned.

“Function of channels A + B” parameter

With the "Colour temperature control” function, in contrast to the "Dimming” function, the color temperature can be dimmed in addition to the brightness or optionally only the color temperature.

It is possible to dim directly to a specific color temperature set via a parameter by briefly pressing a push-button, or to additionally set the dimming value (brightness) and the time in which the values are dimmed to.

For a long press of the push-button, you can set whether only the color temperature or also the brightness should be dimmed.

The prerequisite for controlling the color temperature is that the relevant communication objects are assigned to a compatible output device (e.g. DALI gateway) and a lamp suitable for color temperature control is connected there.

Human Centric Lighting (HCL)

The device can be used in human-centric lighting application because it can control the color temperature of a suitable LED from warm white to cold white (“tunable white”).

Human-centric lighting (HCL) expands the concept of biologically effective lighting with holistic planning and covers the visual, emotional and biological effects of light. HCL supports human health, well-being and performance in the long-term.

Application examples

Association meeting in the meeting room of a restaurant:

First, factual topics are discussed where concentration is required. A cold white light with a high color temperature is suitable here. Later, when things move on to the casual part, the color temperature control can be used to dim to a more appropriate warm white light to create a cozy ambiance.

Educational institutions:

Cool white light during the learning phase to increase attention and warm white light for relaxation during the break.
