The electrical control unit controls the EXV to complete the switching of the initialization state based on the initialization state switching signal. The EXV can acquire the initial position information and adjust the state to the initialized state.

Alternatively, in the case where the air conditioner control device stores the location information and the initialization state information of the EXV by providing the storage unit, in the power down of the EXV, the location information and the initialization state information are stored in the form of a LIN signal To the air conditioner control unit.

The initialization status information is indicated by two high bits (bit 6 and bit 7) of the (N + 1) th byte, where N is one or greater than one. Using the two segments included in the initialization state switching signal, the LIN master node can send state switching and stored location information to the electrical part of the EXV. The other LIN signal is defined in reference to the definition of the two signals described above in response to the data of the LIN frame.
