<p>An automatic building energy manager comprises a plurality of modules (14, 16, 18) connected by a two-line network (10, 12). Each module comprises a data transmitting and receiving device, driven by a microprocessor in order to transmit, via the two-line network (10, 12), data to the other modules and to a central unit, and conversely to receive information through this two-line network. The modules are supplied with power by the two-line network (10, 12). At the time of a simultaneous transmission from two modules, one of them takes priority so as not to disturb the messages transmitted. <IMAGE></p> |
