PURPOSE:To prevent serious faults from occurring by installing a fault inspecting device into which respective signals of the temp. in hot water storage vessels for a high and a low temp. system, the temp. in a double pipe for high temp. water, and the outlet temp. of heat pumps at a high & a low temp. sides are fed and which informs a manager of abnormality. CONSTITUTION:Temp. sensors 20, 21 detecting the temp. of hot water storage vessels 1, 9 of a high and a low temp. systems respectively, a temp. sensor 22 detecting the temp. in a double pipe for high temp. water, temp. detectors 23, 24 detecting the outlet temp. of heat pumps 2, 10 at a high and a low temp. side respectively, and temp. sensors 25, 26 detecting the inlet temp. of the heat pumps 2, 10 at the high and the low temp. side respectively are equipped. A fault inspecting device 33 judging that a threeway cock 6 controlling the inlet temp. of the heat pump 2 at the high temp. side is out of order by using the input signals at various temp. and a fault inspecting mechanism 27 stored in an inner memory is installed and as an information means to a manager, a display mechanism 28 with an alarm, and a printing mechanism 29 are installed. |
