LED error indication does not disappear even if the power is reset when the following error occurs.
<Important>
- Compressor failure
- Low pressure error
- Current sensor error
The following is the reason why this error does not disappear.
These errors can not be judged without operating the system, and the serviceman
would not be able to check it if the system power is turned off before visiting the site for repair.
To reset this error and operate the system, DIP-SW4-4 setting shall be changed.
