<p>PROBLEM TO BE SOLVED: To provide a hot-water supplier the user of which can set the hot water supply temperature of the supplier as comfortable as possible at the time of causing the supplier to restart hot water supply by issuing an operation starting command after the hot water supply from the supplier is stopped due to a communication error between a control section and a remote controller. SOLUTION: When the operation starting command is issued, the control section discriminates whether or not the remote controller is connected by communicating with the controller and, when the controller is connected, stores the operating history of the remote controller indicating that the remote controller has been in a connected state in a nonvolatile storage means, and at the same time, starts the hot-water supplier at a target hot-water supply temperature commanded through the remote controller. When the remote controller is not connected and the operating history is not stored, the control section starts the hot-water supplier at a preset high temperature. When the remote controller is not connected, but the operating history is stored, the control section starts the hot-water supplier at a preset continuously operating temperature which is lower than the high temperature.</p> |
