Systems for “intelligent living” are designed to react as efficiently as possible to changes in temperature, light and air moisture and to control them automatically and precisely. The denro One is a room controller featuring a very clear arrangement and is designed for the automatic control of living spaces. With its purist design and plain language of form it fits easily into a variety of different living environments. The consistently frameless design of this controller lends it an elegant appearance and makes it look as if it is floating in mid-air. A remarkable design detail is a shadow gap facing toward the wall, which lends the denro One a high degree of brand recognition. The controller offers highly intuitive user comfort. Via a quick-response touch panel and a rotary knob it facilitates central control over light, electronics, heat, air-conditioning, ventilation and home entertainment. Using common bus systems such as KNX, SPS or EnOcean, it thus allows the management of the entire automation of a building, embodying a future-oriented prerequisite toward a sustainable and energy-efficient use of a building. Due to its clear and purist design this controlling device reduces the complexity of such systems. Its intuitive controllability turns into a true user experience.
