Eelectron MULTI.SENSOR KNX is a smart and reliable sensor combining information on presence, brightness, humidity, temperature and sound, manages effectively heating, cooling, lighting, shading control and room optimization with a flat compact design of just 8 cm diameter. Combining all those information the Eelectron KNX Multi Sensor complies with Leed®, Breeam® and Well® requirements for buildings. It allows also different functions along with presence detection such as a comfort closer to reality thanks to brightness control and the “Circadian Rhythm” logic. The presence detector detects even smallest movements and temperature differences, ideal for all situations. Furthermore the integrated sound sensor makes it is the ideal solution for rooms with parts not totally visible to the infrared sensor. Presence detection, has independently configurable channels with different functions that can be activated: presence with or without brightness control and with automatic or semi-automatic detection; constant brightness independent or presence dependent with automatic or semi-automatic activation.
