Each of the received state information data is stored in a memory unit of the central controller in a predetermined unit and detects an abnormal operation of each of the multi-air conditioners from the stored state information data.

In this case, the method for detecting an abnormal operation of each of the multi-air conditioners compares the reference state information data generated when the multi-air conditioners operate normally with the state information data received from each of the multi-air conditioners. It can be detected by judgment. (S1)

Next, the error information generated in the outdoor unit or the indoor unit and the device is extracted from the state information data detected as the error state, and the extracted error information is filtered and classified according to the degree in a predetermined step.

Each classified error information is grouped by date or corresponding device to generate an error message.

Next, the virtual sender information for transmitting the error mail is formed through the user information of the multi-air conditioner central control system, and the receiving server information of the set service center is confirmed. (S2, S3)

Next, an attempt is made to connect to the receiving server through the Internet network, and when an access connection is made, an error mail including an error message stored in the central controller is generated and delivered to the receiving server. (S4 to S6)

At this time, the error mail is generated by the SMTP method and transmitted through the Internet network, and the service center analyzes an error message included in the received error mail and performs a corresponding operation accordingly.

In particular, the error mail may be transmitted to the receiving server of the service center repeatedly at predetermined set periods so that the cause of the error may be more clearly identified at the service center, and the correct response may be performed accordingly (S7, S8). )

As described above, the central control system of the multi-air conditioner and the error notification method thereof according to the present invention have been described with reference to the illustrated drawings, but the error state is detected from the state information data of each multi-air conditioner, and an error mail is generated accordingly.
