Apparatus and method for detecting a communication abnormality in a multi-type air conditioner
First Claim
1. An apparatus for detecting a communication abnormality in a multi-type air conditioner by performing data communication with peripheral devices, the peripheral devices including an outdoor unit, a plurality of indoor units, a repeater and a wired remote controller, the apparatus comprising:
- a level converter for serving as an interface to allow multiplex communication between the apparatus and the peripheral devices; and
an abnormality detector connectable with the peripheral devices from a remote site through the level converter, the abnormality detector detecting a communication abnormality in the peripheral devices by automatically changing an operation mode thereof into a slave or master mode depending on whether an operation mode of each of the peripheral devices connected thereto is the master or slave mode.

Abstract
An apparatus and method for detecting a communication abnormality in a multi-type air conditioner is disclosed. The apparatus, which performs data communication with peripheral devices having an outdoor unit, a plurality of indoor units, a repeater and a wired remote controller, includes a level converter for serving as an interface to allow multiplex communication between the apparatus and the peripheral devices; and an abnormality detector connectable with the peripheral devices from a remote site through the level converter, the abnormality detector detecting a communication abnormality in the peripheral devices by automatically changing an operation mode thereof into a slave or master mode depending on whether an operation mode of each of the peripheral devices connected thereto is the master or slave mode. Thus, when the communication abnormality occurs, the communication abnormality can be detected in a convenient way by using the apparatus.
