Check the indoor unit(s).
2-1 Check that you have connected the power and communication
cables correctly. (Communication cables should be connected with
F1 and F2 terminals)
- If the power cables and communication cables are mixed up or
connected incorrectly, the PCB will be damaged.
2-2 Ensure the address of indoor units.
- Choose appropriate address between 0 and F.
- Each indoor unit must have different address.
2-3 Check the thermistor sensor, drain pump/hose, and electronic
expansion valve are connected correctly.

If the outdoor unit is powered on, it will start tracking to check user's
option(s) and number of indoor unit. It takes about 20 seconds.
- At this time, the SEG 1 and 2 on outdoor unit PCB display the number of
indoor unit registered and the SEG 3 and 4 display the number of
indoor units which responded.
