From the left side:
LED1 (Run): When the AC communicated well with the NIM, it will be light; otherwise it will be extinguished.
But when the system stayed in the remote controller lock mode and mode lock state, it will flash with frequency
of 1Hz.
LED2 (Link):It will be light when there is any communication between the AC and Intelligent A/C control and
monitor system including any receiving and sending the signal.
LED3 (ERR):It will flash with frequency of 1Hz when the communication malfunction occurs between the AC
and Intelligent A/C control and monitor system or other malfunctions come from the NIM. It will extinguish in
normality.
