Claims

[Scope of utility model registration request]

(1) Hot water from the hot water tank, water from the water supply pipes, and circulating water in the hot water supply circulation circuit are mixed using a mixing valve, the temperature of the mixed water is detected by a temperature detection means, and the detected temperature is determined from the hot water setting device. The device is equipped with a PID control means that controls the mixing valve based on the set temperature of the water supply pipe, and a water flow switch that detects the water flow of the water supply pipe is provided, and the water flow switch detects the water flow of the water flow switch.
A hot water supply control device comprising a gain control means for controlling the gain of an ID control means.

(2) Utility model registration claim 1, wherein the gain control means increases the gain when the water flow switch is detecting water flow than when it is not detecting water flow. The hot water supply control device described.

(3) The control means makes the gain larger when the water flow switch detects water flow than when it does not detect water flow, and the first predetermined time period elapses after the water flow switch detects water flow. The hot water supply control device according to claim 1, characterized in that the gain is made even larger than when the water flow is being detected.

(4) The control means makes the gain larger when the water flow switch is detecting water flow than when it is not detecting water flow, and after the water flow switch stops detecting and outputting water flow, the gain is set to a second predetermined value. The hot water supply according to claim 1 or 3 of the utility model registration claim, characterized in that the gain is the same as when a water flow is detected or a larger gain than when a water flow is not detected until time elapses. Control device.
