• Communication error between indoor and outdoor units

Indoor unit display

Criteria

Cause of problem

Outdoor unit display

1. How to check

Yes

Compare the number of setting values of

setup switch for the number of indoor unit

installed for the outdoor unit PCB and the

number of actual indoor units installed.

Press the reset key (K3) of the outdoor unit PCB

then check the display part to see the number

of indoor units responding to the tracking.

Remove communication line from the outdoor

unit to indoor units then measure 2 lines on the

outdoor unit with SCOPE.

Is there any response from indoor units

on the display part during tracking?

Check the communication line from the outdoor unit

to indoor units and if there is no problem, find an

indoor unit that hampers communication by making a

connection to each unit and replace the indoor unit PCB

after checking out lines.

At that time, is the power between

the 2 lines a square wave with DC±0.7?

Is the number of actual

indoor units installed and the number

of setting values of setup switch for the number of

indoor unit installed

identical?

Set the correct number of indoor units on the

outdoor unit switch and press the reset key (K3)

on the outdoor unit PCB to execute tracking.

After 2 minutes, find an indoor unit that shows a

communication error then check if PCB address

setup has overlapped.

(If an indoor unit's address is overlapped,

communication error occurs)

- In that case, all indoor units with wrong

address setup for more than 2 will have

communication error.

If there is any problem with the address,

check the communication line then replace

indoor unit PCB

Check the outdoor unit PCB communication line

and connector then replace the PCB

Yes
