PURPOSE:To make it possible for all the remote controllers to set hot water temperature via two-wire signal lines by providing priority changeover means only at a bath remote controller for a bathroom and hot water temperature setting data outputting portions of the bath remote controller and sub remote controller for a kitchen, respectively at the transmitter-receiver circuit, and also providing an output buffer selecting both hot water temperature setting data and transmitting the same according to the content of priority changeover data. CONSTITUTION:When a priority changeover switch 16 of a bath remote controller 7 is changed over and data is set to '1', priority changeover data of reception determining data of a main body 1 and transmission data 20, signal data of a main remote controller 5 and reception determining data 18b of the main body 1, are successively set to '1'. Similar transmission and reception are carried out at a sub remote controller 6 when priority reception data of all the reception determining data 18a-18c coincide with each other, hot water determining data are transferred from an output portion 8a or 8b to an output buffer 8d in accordance with the content of priority changeover data 8c at a reception determining part 19, and are outputted to a sequence control circuit 10 as determined data 21, thus conducting the hot water temperature control. |
