PROBLEM TO BE SOLVED: To assure safe use by resetting a hot-water supply setting temperature display that has been turned off, only for a fixed amount of time when a hot water supply setting temperature display means is forcibly turned off for saving power and then the setting of a hot-water temperature is changed by a remote controller in a hot-water supply machine where a plurality of remote controllers are connected. SOLUTION: In a bath device consisting of a bathroom remote controller 1, a sub remote controller 2 being provided outside the bathroom, and a communication cable 4 for connecting both the remote controller 1 and 2 to a combustion control circuit 3 in the body of the hot-water supply machine, each of the remote controllers 1 and 2 display temperature on each display by receiving the temperature of hot water at present time. Also, each of the remote controllers 1 and 2 is provided with a power- saving switch for operating a function for turning off the display. In this case, when for example a bathing person turns off the display of the remote controller 1 in a bathroom and then another person changes the temperature of supplied hot water by operating the remote controller 2, the display of the temperature of the supplied hot water of the remote controller 1 in the bathroom is reset temporarily, thus indicating that the temperature of the supplied hot water has been changed.
