Embodiment 1
[0038] Such as image 3 , Figure 5As shown, the present invention includes a main control assembly 1, a power supply and an auxiliary control assembly 2, the main control assembly 1 includes a main chip 11, and a variety of air conditioner models (such as wall-mounted, ceiling, pipeline, cabinet, etc.) are integrated in the main chip 11 The control program of the work, and the control program of each specific air conditioner is provided with a corresponding logic level signal, which is convenient for the main chip 11 to call the control program. The power supply and auxiliary control assembly 2 is a collection of control circuits of multiple models (such as single cooling, heating and cooling, and electric heating) in the same model. The power supply and auxiliary control assembly 2 is connected with the internal equipment of the air conditioner (such as fan, heat exchanger, etc.), and controls the operation of the internal equipment of the air conditioner.

Embodiment 2
[0044] Such as Figure 6 As shown, the control method adopted in this embodiment is the same as that in Embodiment 1, and the logic level signal source also includes a voltage source, a resistor, and a machine information setting component 4 . The difference from Embodiment 1 is that the negative electrode of the voltage source of the logic level signal source in this embodiment is connected to the pin 15 for reading the logic level signal through the machine information setting part 4, and the positive electrode is connected to the pin 15 through the resistor 14'. connect.
[0045] Therefore, when the power supply connected to the main control unit and the auxiliary control unit are powered by a three-phase power supply and a wall-mounted heating and cooling air conditioner with a horsepower of 1.5, such as Figure 4 As shown, when the logic level signal required to be read by the pin 15 is 1010011011, the first, third, sixth, seventh, ninth, and tenth bits of the output ter...
Embodiment 3
[0047] Such as Figure 7 As shown, the control method of this embodiment, the composition of the logic level signal source and the connection relationship are all the same as those of Embodiment 1. The difference between the two is that the machine information setting part 4 and the connecting part 3 are designed on a printed board superior.
