Abstract

An object is to provide a remote controller of an air-conditioning system that enables operation state diagnosing with high accuracy even after a long-term use.

A remote controller of an air-conditioning system having an outdoor device, and an indoor device connected to the outdoor device includes a communication unit that is capable of performing bidirectional communication with the indoor device in a wired or wireless manner, and a memory that has stored therein a plurality of operation-state diagnosing tables for every operation mode that are used in maintenance and inspection of the air-conditioning system. An appropriate one of the operation-state diagnosing tables is used according to an operation mode and as operation time of the air-conditioning system.

Claims

1. A remote controller of an air-conditioning system including an outdoor device, and an indoor device connected to the outdoor device, the remote controller comprising:

a communication unit capable of performing bidirectional communication with the indoor device in a wired or wireless manner; and

a memory that has stored therein a plurality of operation-state diagnosing tables for every operation mode that are used for extracting necessary inspection items from an operation state in maintenance and inspection of the air-conditioning system, wherein

an appropriate one of the operation-state diagnosing tables is used according to an operation mode and an operation time of the air-conditioning system.

2. The remote controller of the air-conditioning system according to claim 1, wherein determination is made whether current operation times of the indoor device and the outdoor device are equal to or less than set operation-time threshold values, respectively, and the operation-state diagnosing tables stored in the memory can automatically be switched based on a result of the determination.

3. The remote controller of the air-conditioning system according to claim 1, wherein the operation-state diagnosing tables are correctable.
