  • Patent number: 6285912
    Abstract: A multifunction user interface provided as an add-on option to a more basic multifunction sensor which does not provide a display or keypad, to provide a local user interface to access and control parameters of a control network. The basic multifunction sensor provides a plurality of parameter sensors in one sensor housing, and can interface with and control operation of one or more processor control systems connected by a network bus in an occupied space networked environment. The basic sensor comprises at least an occupancy sensor, a temperature sensor, and a common network communications and control processor coupled to a common communication transceiver. This allows the basic multifunction sensor to interface with and control operation of one or more processor control systems in an occupied space networked environment.
