Remote control device for sanitary installations, especially for whirlpools

The control unit of the sanitary system is designed, so that the transmitter-receiver unit (4,5) assigned to it, is integrated in the base station (3). The hand transmitter (1) and the base station (3) with the radio modules (4,5,13,14, fig.2) working in the radiowave range are equipped for bi-directional data transmission. So that the base station (3) has a series interface for a cable connected data exchange with the spatially separated control unit. The hand transmitter (1) and the base station (3) are assigned in pairs by a code deposited unalterably in the electronics of the hand transmitter (1) and stored non-volatile in the base station (3), and the data transmission results in packet form in half duplex operation.
