Abstract

PURPOSE: To prevent mis-indication among plural remote controllers by sending an operation signal to all remote controllers from a hot water supply device main body with respect to a state change of the hot water supply device main body and discriminating the correctness of reception every time a reply signal is received. CONSTITUTION: When a state change such as combustion start takes place in a hot water supply device main body 9, a transmission means 11 of the hot water supply device main body 9 sends an operation signal after the operation state change to a remote controller 1 in radio connection to the hot water supply device main body. Each remote controller 1 uses a reception means 3 to receive the operation signal and displays an indication corresponding to the operation signal by a display means 4 employing a liquid crystal display device. When the remote controller 1 receives normally the operation signal from the hot water supply device main body 9, the remote controller 1 returns a reply signal. In this case, a transmission means 2 is used to send the reply signal based on an address stored in an address storage means 5 by deviating its transmission timing. In this case, the operation signal is sent to all the connected remote controllers 1 by one transmission and the hot water supply device main body 9 receives the reply signals from all the remote controllers 1 and the reception means 10 discriminates it that each remote controller 1 receives the operation signal correctly.
