(EN) The invention relates to a control system (1) for controlling electrical appliances (G1, G2, G3, G4) in a building. Said control system comprises a central control unit (2), cabling (8) which is connected to the control unit (2) and which comprises a plurality of data lines (14) to which the electrical appliances (G1, G2, G3, G4) can be connected in order to be connected to the central control unit (2), at least one command signal receiver device (IE1, IE2) with which at least one electrical appliance is respectively associated, and which is connected to the central control unit (2) by means of corresponding command signal data lines (16) of the cabling (8), and at least one mobile command signal transmitting device (FB1, FB2), by which means command signals can be transmitted to the central control unit by means of each associated command signal receiver device (IE1, I'2). Said central control unit (2) is embodied in such a way that control signals can be generated, on the basis of the command signals supplied by the mobile command signal transmission device (FB1, FB2) to said control unit, and can be supplied, via control signal data lines (18, 20) of the cabling (8), to the respective electrical appliance (G1, G2, G3, G4) in order to control the properties of the same.
