The LCD does not turn off. Has a check code been detected? The LCD will still be on when a check code has been detected. Erase 
the check code.
Sometimes the LCD becomes 
black for a moment.
The LCD's antistatic control is 
working.
Temporarily stop the LCD periodically to prevent LCD burn-in. Not a 
malfunction.
The setting displayed on the 
local remote control does not 
match the setting displayed 
on this Unit.
Does the operated air conditioner 
match the actual air conditioner?
Operate another air conditioner and check if the actual air 
conditioner operates.
I would like to frequently 
change detailed settings such 
as the set temperature and 
operation mode for all air 
conditioners.
Only "ON" and "OFF" can operate all 
air conditioners at once.
You can set the set temperature and operation mode, etc. for all air 
conditioners group by group. Please group the air conditioners.
When local remote control 
operation is prohibited, if there 
is a power failure, the local 
remote control prohibited 
status will be cancelled when 
the power returns.
- Ask service personnel if you want to continue the local remote 
control prohibited status after returning from a power failure.
FILTER information can be 
reset even when the FILTER 
sign is not displayed.
The FILTER signs lights up 
depending on the accumulated 
operation time.
As the operation time accumulates, the FILTER sign lights up when 
the preset operation time is reached.
The FILTER sign information can be reset to clear the accumulated 
time for cases such as when FILTER cleaning is carried out before 
the FILTER sign turns on.
I want to check the software 
version.
