The invention provides a method for controlling a remote controller of a push-to-talk (PTT) intelligent air condition, which is characterized by comprising the following steps: arranging a temperature sensor and an intelligent button; detecting environment temperature with the temperature sensor to obtain a detecting electric signal corresponding to the environment temperature; converting the detecting electric signal by means of A/D, and inputting into a CPU to obtain a digital environment temperature value; previously defining one or two temperature set value(s) with software; when an operator presses the intelligent button, judging the relationship between the environment temperature value and the defined temperature set value(s) by a software program though the CPU to simultaneously transmit corresponding instructions of starting, working mode, air quantity controlling, air direction controlling, and the like; and transmitting the instructions which are transmitted by the CPU though an infrared ray transmission module. The method can automatically start up the air condition and select a cooling mode, a heating mode and a ventilating mode or a dehumidifying mode according to the environment temperature only by pressing the intelligent button no matter in winter or summer. The method is convenient in operation, fast, is time saving and labor saving, is especially suitable for the old, children and persons with low literacy, and is particularly for blind people.
