The invention discloses a matching method of a universal wire controller. Parameter addresses corresponding to all functions of the wire controller are set to be changeable modes, and the addresses are set within the range of 0000-9999, so that the addresses are suitable for mailing addresses of various air conditioner main controllers. Setting of the mailing addresses of the wire controller is transferred to an air conditioner main controller developer from a wire controller developer, so that a wire controller manufacturer only needs to provide one wire controller, and management is facilitated while the research and development cost is reduced. A corresponding central air conditioner main manufacturer only needs to automatically adjust the mailing addresses of the wire controller at themain controller research and development stage to achieve matching, the wire controller manufacturer does not need to be entrusted independently, thus the research and development period is shortened, and the research and development cost is reduced.
