To provide a system controller of hot water supply apparatus in which location of failure or recognition of reoperation of a hot water supply apparatus can be carried out quickly, recognition miss of the hot water supply apparatus causing failure can be found in the early stage and time indication can be prevented from being shifted between hot water supply apparatus.
In the system controller SC for controlling the number of operating hot water supply apparatus Q1-Q4, presence of a failure is confirmed for each hot water supply apparatus Q1-Q4 using a communication function and the recognition results are presented at a display section 20. Furthermore, the system controller specifies a failed hot water supply apparatus through communication and operates the specified hot water supply apparatus while setting it as a hot water supply apparatus being operated at first in the control of the number of operating hot water supply apparatus thus recognizing reappearance of failure.
