When XQ) is energized and the water temperature in the hot water tank (B) is below a predetermined value, the contact point (2#%V) of the temperature detection stem is closed, so it is used for the heat source secondary pump (To). The magnetic contactor fill (sgPQ) is energized. Also, relay carp #
(XQX) Sono contact (XQ-1) (XQ-
2) and (XQ-8) are respectively reversed from the b side to the a side, and the fill (MVi) of the first solenoid valve (6) is instantly energized and the first solenoid valve (6) The circuit is opened, the coil (8) of the second solenoid valve (7) is deenergized with a delay, and the second solenoid valve (7) is closed and the heat source-next pump (September) continues to operate. Therefore, regarding water circuit (2),
Heatpo water is supplied and l! 1 solenoid valve (6) and flow j
It passes through the resistor Wlljll valve (8), is guided to the supply heat exchanger (3), passes through the heat source - next pump ψ), and returns to the heat pump chiller unit (1).
