Building Control GAMMA instabus


New buildings must satisfy an abundance of requirements: they must be attractively designed, functional and economical in everday use. They must allow flexible use of space and be adaptable to the wishes of individual tenants. The lighting and indoor atmosphere must merge convenience with energy efficiency, and people and assets must be adequately protected against hazards and damage. Today, all these requirements can be met thanks to GAMMA instabus. GAMMA instabus building control offers intelligent solutions and products that help you achieve higher energy efficiency, improved comfort and a healthy environment for the well-being of all building users.

Tunable White

Perfect lighting with Tunable White

Light affects the way we work, play and feel. For your customers, and the occupants of their buildings, delivering the right light is important. Dynamic color temperatures not only promote a good room atmosphere but contribute to human well-being. This follows the concept of Human Centric Lighting, a way of light planning that responds to human needs. While cold white light promotes concentration, warm white lights has a calming effect. In this way, the light in a room can be positively adjusted to individual requirements and situations.

The new presence detectors WIDE - One room. One sensor. Highest efficiency for perfect places.

Buildings are increasingly intelligent. To turn rooms in buildings into perfect places, intelligent devices are needed – like the new presence detectors, which combine five functions for a pleasant atmosphere and energy savings in the room. The new presence detectors capture data on CO2, temperature, humidity and brightness and thus control not only the illumination systems but also ventilation and heating systems. This creates optimal ambient conditions in the space – for maximum comfort and the highest energy-efficiency.
