A remote-control system permits user definable grouping of transmitters, which send wireless messages encoded with transmitted key addresses, and of receiving decoders, which are coupled via a bus to a plurality of actuators. The decoders each include a corresponding programmable storage device which can be programmably occupied as an association table, and assign in a freely definable manner assigned key addresses, which are oriented according to transmitter command keys, to each transmitted key address. Each assigned key address designates a particular actuator so that desired groups of actuators may be controlled with a single message.

Remote-control system for large rooms with free grouping

An electronic time switch for the time-limited actuation of appliances which are supplied with alternating current, whose load component is actuated by an electronic control element, and which includes terminals which supply the load component as well as the control element. A first storage element is charged during the inoperative condition through a rectifier, wherein the first storage element charges a second storage element upon initiation of load operation through the intermediary of a pushbutton with switching functions, through a recharging branch having a current limiting resistor. The recharging branch consists of a parallel circuit including an ohmic resistor and a threshold rectifier.
