と同一である。Next, the operation in the case where one of the low temperature tank and the high temperature tank is supplying liquid due to insufficient liquid amount and the other side has insufficient liquid amount will be described with reference to FIG. (Since the same liquid supply operation is performed regardless of which tank has a shortage of liquid first, the low temperature tank side is shown first and the high temperature tank side is shown in FIG. 3). The detection float switch 4a detects the lower limit, and the operation until the pump 11 is stopped is the same as the liquid supply operation to the low temperature tank side, while the testable high temperature heat transfer medium liquid amount lower limit detection float switch 4b is the lower limit. When the signal is detected, the signal is put in a standby state and after the liquid supply to the low temperature tank side is completed (after the pump 11 is stopped), the signal is received and the liquid supply to the high temperature tank side is started. After that, it is the same as the liquid supply operation to the high temperature side.
