4-4-25 Communication Error between MCU and Outdoor Unit

1.   Inspection Method

Yes

Yes

MCU Installation Quantity Setup Switch for 

Outdoor Unit PCB Compare and check the set values 

and the actual MCU installation quantity.

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

and check the display module to check the quantity 

of MCU which responds to tracking. 

Remove the communication cable which 

connects the outdoor unit to the MCU, and measure 

the 2 cables of the outdoor unit with a scope.

Is there any response from the 

MCU on the display module during tracking? 

Check the communication cable which connects the outdoor unit 

to the MCU. If there is no peculiarity, connect the MCUs one by 

one to find the MCU which interferes with the communication 

to check and change the MCU PCB. 

Is the voltage between the 2 cables 

a square wave with DC±0.7V or more?

Are the quantity of 

the actually installed MCUs and the set value 

of the installation quantity setup 

switch the same?  

Correctly set the installation quantity setup switch 

of the outdoor unit MCU, and press the reset key (K3) 

of the outdoor unit PCB to re-execute tracking. 

After two minutes, find the MCU which displays 

the communication error and check if the PCB 

address settings are overlapped.

(A communication error occurs if the indoor unit 

addresses are overlapped.)

- In this case, a communication error will occur 

in every MCU (2 or more units) with the address 

incorrectly set.

If there is no peculiarity in the address, then check 

the communication cable and change the MCU PCB. 

Change the communication cable and the connector 

of the outdoor PCB, and then change the PCB. 

Yes

No

No

No

  Essential Requirements before Changing PCB in Case of Communication Error:  Refer to p.4-80

Outdoor unit display

Indoor unit display

-

Judgment Method

• Communication Error between MCU and outdoor unit.

Special Cause

• Reference below.
