The worldwide standard for home and building control Flexible operation of entire room automation via KNX Straightforward operation of all room-related disciplines in office buildings – with the room operator unit UP 227 Ease of operation The UP 227 as a single room operator unit controls all room functions. Be it temperature control with an integrated temperature sensor or the control of fans, lighting, blinds or screens, etc. All can be operated in a uniform way. A key lock feature is available to prevent inadvertent operation. An LED on the housing front facilitates orientation at night and indicates malfunctions should they occur. Ease of use The bundling of all functions in a single unit reduces the effort required for installation and configuration. Presettings and a library with symbols simplify commissioning. The room operator unit can be easily combined with the DELTA frame programs from Siemens. Being a KNX- compatible device, it can be seamlessly integrated into any type of building automation and control system. High level of flexibility The room operator unit controls and monitors HVAC plant as well as lighting and shading. A weekly scheduler function is capable of performing up to 40 individual scheduling tasks. Three pairs of keys can be freely programmed. Also, the positioning signal for HVAC control can be easily adapted, e.g. to valve characteristics. S tandardized, easy-to-use room operator unit for all disciplines F ast, straightforward installation, commissioning and integration into KNX systems I ndividual, flexible settings for operation and control L ower energy costs thanks to energy saving functions Reliable efficiency Energy-saving operation includes night mode, changeover to protection mode when a window is opened and scene control, for example.
