METHOD OF CONTROLLING COLD AND HOT WATER SUPPLY SYSTEM

摘要

Disclosed herein is a method of controlling a cold and hot water supply system. A boiler cold-water supply pipe, a hot-water distribution pipe, a mixed-water pipe and a circulating-water pipe are arranged to enable smooth circulation. A timer is provided on a control unit to prevent overheating or damage. A tap of a zone visually and auditorily provides a high temperature warning to prevent other users from getting burnt. The water temperature automatically returns to a basic set temperature after a predetermined time. The power of a hot water system is cut off unless flow is detected by a flow sensor within a predetermined period of time, and power is supplied to only a control zone in which flow is detected when hot water is used. A back flow from a water circulating pump to a circulating-water pipe is prevented when the water circulating pump is not in operation.
