The invention discloses a controlling device of an air conditioner and a controlling method for the controlling device. The controlling device of the air conditioner comprises a data editor, an air conditioner controller for storing data frames and sending command frames and the air conditioner for receiving the command frames and executing operation; the data editor is used for operating program codes, displaying data templates, editing the templates and generating the data frames; the air conditioner controller is used for guiding and storing the data frames, converting the data frames into the command frames and sending execution signals; and the air conditioner is provided with a
receiver corresponding to the air conditioner controller, the
receiver is used for converting the execution signals into execution codes, and a control
chip of the air conditioner carries out operation according to the execution codes. The air conditioner controller comprises a micro controller unit (MCU) serving as a
processing module, a
read only memory (ROM) serving as a program storage module and a
random access memory (RAM) serving as a random storage module, wherein the MCU is used for
processing key instructions or sound instructions and executing instruction operation; the ROM is used for storing customized program codes; and the RAM is used for storing temporary data. The controlling device has the characteristics of simple and reasonable structure, flexibility in operation and wide application range.
