入してなるポンプの駆動制御装置。In a hot water supply device that includes a hot water storage tank and a pump that pressure-feeds hot water from the hot water storage tank to multiple faucets, the pressure of nine hot water supply paths from the pump to the faucets is detected, the pressure is closed when the set pressure is below the lower limit value, and the upper limit value is set. A pressure switch that opens when the pressure switch is higher than the set flow rate, and a flow rate switch that detects the flow rate of hot water flowing through the hot water supply path, closes when the flow rate is lower than the upper limit value of the pressure switch, and opens when the flow rate is lower than the set flow rate. , a pump drive control device in which these pressure switches and flow rate switches are inserted in parallel into the pump's power supply circuit.
