An energy control and communication system for use in hotels comprises temperature sensing and control means situated in an area where temperature is to be controlled. Computer means for controlling said sensing and control means is located remotely from said area and communicates with the sensing and control means via a data link formed by a television areal system. The data link can also be used for communicating other data between the area and the computer means and a television receiver in the area can be linked to the system to display data. |
