供暖系统
摘要：
热水供暖系统(2)具有供暖机(76)、热泵(50)、燃烧器加热装置(82)、供暖用水循环通路(71)、热敏电阻(78)和控制装置(100)。在热敏电阻(78)所检测到的温度(T1)在供暖设定温度－TA以下时、或者在热敏电阻(78)所检测到的温度(T1)在供暖设定温度－TB(TB小于TA)以下的状态持续规定时间时，控制装置(100)启动燃烧器加热装置(82)。另外，控制装置(100)在热敏电阻(78)所检测到的温度(T1)在供暖设定温度+TC以上时，关闭燃烧器加热装置(82)。
摘要（英）：

A hot water supply system (2) is equipped with: a heater (76); a heat pump (50); a burner heating device (82); a heating-use water circulation passage (71); a thermistor (78); and a control device (100). When the detected temperature (T1) of the thermistor (78) is equal to or less than the set heating temperature minus TA, or when the detected temperature (T1) of the thermistor (78) is equal to or less than the set heating temperature minus TB (TB being less than TA) for a prescribed period of time, the control device (100) activates the burner heating device (82). Furthermore, when the detected temperature (T1) of the thermistor (78) is equal to or greater than the set heating temperature plus TC, the control device (100) stops the burner heating device (82).
