Claims (1)

[Scope of utility model registration request] It has a refrigerant circuit composed of a compressor, a four-way valve, a non-use side heat exchanger, a throttle device, and a use side heat exchanger, and a blower that supplies air to be heat exchanged to each of the heat exchangers. An operating circuit section consisting of a rotary switch for switching between cooling and heating operation, a thermostat for temperature adjustment, etc., and a control circuit section consisting of the electromagnetic contactors for the compressor and blower, etc. are connected by a connector. An air conditioner equipped with a standard specification electric circuit is composed of a first connector, a lead wire, and a second connector provided in the middle of the lead wire, and the lead wire can be connected by connecting or disconnecting the second connector. A connector unit that can be opened or connected is provided, and by connecting this connector unit between the operating circuit section and the control circuit section, it is possible to switch from manual cooling and heating operation to automatic operation using a thermostat for temperature adjustment. In addition to the switching specifications, by removing the second connector in the middle of the above lead wire, you can automatically switch to another temperature control thermostat (room thermostat) installed outside the air conditioner (in an air-conditioned room, etc.). An air conditioner characterized by being able to be changed to a switching specification.
