1. Self-diagnosis of indoor and outdoor units: Allows you to monitor and view the unit's communication data. If problems occur, it automatically runs a simulation test to test the indoor and outdoor units step by step. Finally, it determines the type of malfunction.

2. Indoor unit test: In case of communication malfunction or if the indoor unit malfunction needs to be verified independently, the tester simulates communication between the outdoor unit and the indoor unit, and in the meantime intercepts and acquires the data of the indoor unit.

3. Outdoor unit test: In the event of a communication malfunction or if an outdoor unit malfunction needs to be verified independently, the tester simulates communication between the indoor and outdoor units, simultaneously intercepting and acquiring data from the outdoor unit. In this mode, remote control data can be directly received.
