<P>PROBLEM TO BE SOLVED: To provide a gas heat source machine capable of operating by directly connecting an auxiliary power supply that supplies a DC current, without any intervention of an inverter. <P>SOLUTION: A gas heat source machine 1 includes: a heat source machine body 2 connected to an external power supply 8 that supplies an AC current; and a remote controlling device 3, which is connected with a connection line 6 to the heat source machine body 2 via an inverter 4 and which operates with a DC current, for instructing an operation to the heat source machine body 2. The remote controlling device 3 includes a connection terminal 5 to which an auxiliary power supply 9 supplying a DC current is detachably connected. The gas heat source machine is configured to be capable of switching between a first operation condition in which electric power is supplied from the external power supply 8 via the heat source machine body 2 and the inverter 4 to the remote controlling device 3, and a second operation condition in which electric power is supplied from the auxiliary power source 9 connected to the connection terminal 5 to the remote controlling device 3 and the heat source machine body 2 to operate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
