Their precision is far superior to that of conventional movement detectors. Not only lighting systems but heating systems and air-conditioning systems can be controlled intelligently and efficiently with presence detectors. Empty rooms in which the lights are on and the air-conditioning runs at full power are now history. There is one presence detector for each need. — Office single — Office open plan / with or without windows — Gym Sport facilities — Toilets The office champion If a person works exclusively at a computer, only minimal movement is to be expected. Here detection needs to be especially accurate and precise. On/off of lights depending on occupancy is only the beginning. Using constant lighting control, the required level of brightness can be achieved using the available “natural light” and the controlled addition of “artificial lighting”. Only the necessary amount of electricity is therefore consumed. Blinds, as well as heating, ventilation and air-conditioning systems can be controlled efficiently with presence detectors. Practical experience show that the reduction of the room temperature by 1 °C can reduce the consumption of energy by 6 %. In open space offices a master/slave function allows a difference brightness level between lights closer to the windows and the ones in the middle of the room without the installation of a second light sensor. ABB offers a wide range of presence detectors to meet the requirements of all type of offices. For a spacious area In spacious areas with a high ceiling as gymnasiums and sport facilities, a light control depending on the occupancy (training, game with public, event, etc.) or depending on the outside brightness, can avoid unnecessary expenses. In this areas the presence detector must accurately detect movement from a great height and at the same time be protected by a protective basket against damage. Same as before, heating, ventilation and air-conditioning systems can be controlled with presence detectors and help saving energy. For example, if the room temperature is reduced by 3 °C during prolonged absence, 18 % of the energy can be saved. The Busch-Watchdog Presence tech, Busch-Watchdog Presence tech DualLINE and the new Busch-Watchdog Sky KNX are ideal for these areas. 3 Potential savings for automatic lighting control * Automatic light (occupancy controlled, not brightness controlled) Automatic light (occupancy controlled, dependent on brightness) Automatic light (occupancy controlled constant lighting control) Automatic light (occupancy controlled constant lighting control with automatic blind control [louvre adjustment dependent on position of the sun]) % 0 10 2...
