PURPOSE:To control a plurality of tea servers by means of centralized supervision. CONSTITUTION:Tea servers 10-1 to 4 are made to automatically distill tea in response to the control of a pushbutton switch 13 when a controller 15 controls a distilling device 11 via a relay circuit group 16 according to the condition of the distilling device 11 detected by a condition detecting device 12, operating conditions set by an operating condition setting device 14, and the control of the pushbutton switch 13. Each of the tea servers 10-1 to 4 has a data originating circuit 21, a parallel-serial conversion circuit 22 and an output circuit 23 and outputs to a reception device 10 which expresses both the condensed detected condition and the set operating conditions and a control signal output from the controller 15. The reception device 10 comprises an input circuit 31, a reception controller 32 and an alarm device 3 and supervises the tea servers 10-1 to 4 according to the input condensation and informs users of the result of the supervision. |
