Abstract
Abstract A room monitoring and control system for use in multi-room buildings, such as hotels, institutions, apartments, and also, for example, in passenger ships, has a room information processing unit (22) for each room, a temperature sensor (28) connected to the unit for sensing the temperature in the room, a temperature control means (32) for controlling the temperature in the room and connected to the unit, a person presence sensor (26) in the room and connected to the unit so as automatically to cause the temperature control means to change the temperature to one predetermined value when a person enters the room and to change the temperature to a second predetermined value when a person is not in the room. A central processor is connected to a group of room units to receive information therefrom.
