ABSTRACT:
Installation comprising several receiving points and several transmitting points. A control installation especially useful for controlling the operation of roller blinds or shutters. The control installation has several receiving points (4), several transmitting points (1) and the relay points (2) are connected to a common BUS line so as to be able to intercommunicate. The transmitting points (1) are provided in order to transmit signals on the BUS line. Each signal is a frame formed of at least one identifying element and of at least one element defining an order to be executed by the receiver. A particular address code, to which the identifying element corresponds is assigned to each transmitting point. The relay points are equipped with a logic processing unit having memories which are provided in order to store at least one identifying element. The allocating of the address to the transmitter allows the control installation to exhibit very high flexibility.
