The apparatus includes an outside temperature sensor (1) with a transmitter (7). Several control apparatus (5) are provided which each has a receiver. The transmitter and the receivers of the high frequency radio path are allocated to each other via address codes. Preferably, each control apparatus has a memory which stores the identifier of the transmitter. Each control apparatus includes an input unit, e.g. a switch, for entering the identifier of the transmitter. The outside temperature sensor is provided with a code generator (14), a solar cell (10) and a storage unit (12). |
