摘要： PROBLEM TO BE SOLVED: To provide a warm water heating system capable of self-diagnosing a fault of a thermal valve provided on a warm water supply route. SOLUTION: First, whether the warm water heating system 1 is operated or not is judged as an inner process of a controller 5 of the system 1. If the system 1 is operated, whether a sensed temperature of a temperature sensor 14 exceeds a predetermined given temperature or not is judged. If the sensed temperature is lower than the given temperature, a closure fault of the valve 4 is judged. If the system 1 is not operated, it is, contrarily, judged. If the sensed temperature of the sensor 14 exceeds the given temperature, a closure fault of the valve 4 is judged.

摘要： PROBLEM TO BE SOLVED: To enable a failure diagnosis back-up device which performs the function of communicating with a hot-water supplier to also perform the function of diagnosing the failure of the thermal valve of the hot-water supplier and the failure, etc., of hot water heating equipment. SOLUTION: The failure diagnosis back-up device 1 is constituted communicably with the control section 21 of the hot-water supplier through an interface device 2. The device 1 stores a sequence necessary for the diagnosis of the failure, etc., of the thermal valve of the supplier 2 and transmits an operation command to the supplier 2 based on the sequence. The device 1 also obtains the information on the operating state of the supplier 2 from communication and the inputting operation to an input means 14 and diagnoses the presence/ absence of a failure following the stored sequence based on the information.

摘要： PROBLEM TO BE SOLVED: To detect flow rate at the low temperature terminal of a hot water heater by an inexpensive method insusceptible to aging and to provide a hot water heater, and a diagnostic apparatus therefore, in which abnormal conduction of the low temperature terminal can be determined easily. SOLUTION: Flow rate Q2 of a low temperature terminal c is determined not through a direct detecting means, e.g. a flow sensor, but from an water temperature T1 detected by a temperature sensor 2, the flow rate Q1 of a constant flow rate bypass channel f, an water temperature T2 detected by a temperature sensor 3, and an water temperature T3 detected by a temperature sensor 4, according to a formula; Q2=Q1×(T1-T3)/(T3-T2). A decision is made whether the operated flow rate of the low temperature terminal c is appropriate or not using the control section 5 of a hot water heater 1 or an external diagnostic apparatus.

摘要： PROBLEM TO BE SOLVED: To provide a connection type hot water supply device capable of supplying hot water at a set hot water supply temperature, even in case of an opening failure of a water passing flow control valve, while preventing a reduction in hot water supply temperature at the time of switching water passing or water passing stoppage by use of the water passing flow control valve such as a can fluid control valve while omitting an exclusive opening and closing valve. SOLUTION: Each water heater is quantity-controlled by a system controller when can flow control valves are normal. On standby for hot water supply, only the can flow control valve of a main water heater is opened, and can flow control valves or bypass flow control valves of sub-water heaters except it are fully closed. When an opening failure in the can flow control valve of any water heater is detected (YES in SB3), the water heater concerned is separated from the quantity control by the system controller and transferred to independent control (SA5 and 6). As the independent control, when a can flow rate is detected by opening a hot water faucet, combustion is started at MOQ or more and, thereafter, hot water is supplied while adjusting it to a set hot water supply temperature by adjustment of water-hot water mixture flow by the bypass flow control valve (YES in SB7, and 8).

摘要翻译：要解决的问题：为了提供能够在设定的热水供给温度下供给热水的连接式热水供给装置，即使在通水流量控制阀的开启不良的情况下，也能够防止在在省略专用的开闭阀时，通过使用诸如罐式流体控制阀的通水流量控制阀来切换水通过或水通过停止时的热水供应温度。
解决方案：当流量控制阀正常时，每个热水器由系统控制器进行数量控制。在热水供应待机时，只有主热水器的罐流量控制阀才能打开，除了完全关闭之外，可以流过除热水器的控制阀或旁路流量控制阀。当检测到任何热水器的罐流量控制阀的打开故障（SB3中为“是”）时，相关的热水器由系统控制器与量控制分离，并转移到独立控制（SA5和6）。作为独立控制，当通过打开热水龙头检测到罐流量时，在起始或更高的温度下开始燃烧，然后通过调节水热将水调节到设定的热水供应温度通过旁路流量控制阀进行水混合流动（SB7中为“是”，8）。版权所有（C）2005，JPO＆NCIPI
