In the water supply method for a building, the water supply tank method is to temporarily store water in a water receiving tank and pump the water in the water receiving tank to a water supply target, and the water supply main has a direct water supply system to supply water to the water supply target by increasing pressure through a pump by using main pressure; when the discharge-side pressure drops to a predetermined start pressure while the pump is stopped, the control unit starts at least one of the pumps, specifically, the control unit issues a command to a motor unit in the pump to start driving the pump. During the operation of the pump, the estimated end pressure constant control is performed based on the set pressure (set pressure). Specifically, in the case of constant estimated terminal pressure control, the target pressure (SV) is set using the rotation speed of the pump and the target pressure control curve, and in the case of constant target pressure control, the set pressure is set as the target pressure (SV). Further, the discharge-side pressure is set to the current Pressure (PV). Then, PID calculation is performed based on the deviation between SV and PV to set the command rotational speed of the pump. When the estimated end pressure is continuously controlled by the direct water supply, the target pressure control curve may be corrected based on the suction side pressure, and the target pressure control curve is added only to the suction side pressure to calculate the target pressure (SV). Further, when the water usage in the building decreases during operation when there are a plurality of pumps as in the present embodiment, the flow rate detection switch detects that the amount of water is insufficient and sends a detection signal to the control unit, and upon receiving the detection signal, the control unit instructs the pumps to increase the rotation speed of the pumps until the discharge-side pressure reaches a predetermined operation stop pressure, accumulates the pressure in the pressure tank, and then pumps. When the pump uses water again in the building after being stopped by a small amount of water, the discharge-side pressure falls to the start pressure or lower, and the pump starts, which herein is a booster pump.

Storing device information including at least one of the number of pumps, a water supply manner, and model identification information in a nonvolatile memory; the utility model discloses the control unit of product can show the information about the running state of pump, for example, target pressure SV, current pressure PV, operation/stop etc. are shown on external display. By displaying (e.g., frequency) on the same screen, even a user who is not familiar with the product of the present invention can recognize the state of the water supply equipment without misunderstanding; in addition, the control panel may be installed in an environment having a large amount of electrical noise, such as a machine room or a pump room. To cope with this, as a display unit, a display composed of 7-segment LEDs, indicator lamps, mechanical buttons, and the like is more resistant to electrical noise than a liquid crystal display or a liquid crystal display. Even if the operation of the liquid crystal display or the touch panel of the external display is abnormal due to the electrical noise generated by the external environment, the display unit performs the display and the operation at the minimum required for operating the product of the utility model; therefore, the product of the present invention can be installed even in an environment having a large amount of electrical noise.

The control unit may not include an operation panel, i.e., a display unit, but may include only an external display (high-performance display). In this case, all functions of the operation panel can execute all programs through the external display. Since the display itself does not need to be provided, the overall cost can be further reduced.

The present invention and its embodiments have been described above, but the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
