Abstract: The inventive method makes it possible to communicate between an order transmitter and a bi-directional order transmitter-receiver for controlling elements which ensure the security or comfort of a building. The transmission of control orders from the order transmitter to the order transmitter-receiver or from said order transmitter-receiver to other elements is carried out by means of frequency modulated radioelectric signals. Said method is characterised in that in a programming mode, the order transmitter-receiver successively activates and interrupts the emission of electric signals traditionally used for communicating in a frequency modulation mode in such a way that it is possible to transmit data to the order transmitter by means of said frequency modulated radioelectric signals.

Abstract: A drive device with radiofrequency control includes a motor, a radiofrequency receiver for receiving radiofrequency signals and for controlling the motor. Electrical conductors provide power for both the motor and the radiofrequency circuit. The antenna is connected to the radiofrequency receiver and is non-galvanically electrically coupled one of the conductors at radiofrequencies. The control circuit receives radiofrequency signals directly through the antenna or via radiofrequency coupling from one of the power supply conductors. The device has increased ability to receive radiofrequency signals independent of its environment.
