PROBLEM TO BE SOLVED: To provide a connected hot water supply control device which can improve maintenance efficiency by allowing a user to easily state whether it is an abnormal state of high emergency or not when communicating with a maintenance agent, while maintaining production cost.SOLUTION: A connected hot water supply control device includes a remote controller which has a temperature display part for displaying a hot water supply temperature, and which can remotely control the hot water supply temperature. The connected hot water supply control device can receive abnormal state information of a water heater by communication with each water heater. When the abnormal state information is received (STEP 1), a first error code corresponding to the abnormal state information is displayed in the temperature display part instead of the hot water supply temperature (STEP 5). The connected hot water supply control device, when the number of the water heaters in a normal state is equal to or less than a predetermined number set in advance, displays a second error code for notifying that the number of the normal water heaters is equal to or less than the predetermined number in the temperature display part instead of the first error code (STEP 4). |
