At KFC in Viernheim, the largest German restaurant, the frequency changes on a constantly high level, also thanks to the unique lighting concept. The wonderful location in a busy shopping center, is further improved by the attention-grabbing light staging. The colour accents and light intensity in the restaurant change day and night - fully automated via the standardised lighting control system specially customised to the needs of KFC. The brighter the daylight, the more reduced the warm and friendly lighting in the guest areas – the blue effect, which sometimes seems fantastic, is at the same time imperceptibly strengthened. Exactly the right atmosphere to entice passing moviegoers or tired shopers to eat yet another snack. Light has a strong effect on passers-by - KFC in Viernheim is the best proof of this. The frequency is correct, because not only moviegoers feel that they are in the correct film here.

The advantage of the Mangelberger technology for the experienced KFC gastronomer lies clearly in the ability to duplicate it for new building projects and the user-friendliness. Thus the standardised switchgear appears invariably in all German restaurants and even in distant Karachi in Pakistan. No matter which restaurant manager is on duty in Viernheim, the control takes over all substantial functions and always supports same handling and the image-laden sign of the KFC group which always has the same appearance.

To reduce functionalities to only one switch – therein lies the art of standardised technology. Each restaurant manager operates only one single switch at the beginning of the opening hours and the comfort and energy saving programme starts: automatically regulated effect-lighting, night and cleaning lighting, regulation of ambient temperature and climate as well as energy distribution. Thus, lower energy costs are ensured by e.g. a peak load optimisation adapted perfectly to the energy-intensive consumers in the kitchen, e.g. deep fat friers, the ventilation in the guest area is only switched on if guests are actually present.
