Error detection condition
Over-current was detected several
seconds after header compressor
had started.
While header compressor stopped,
current flowed more than the
specified current and was detected.
Compressor 1 case thermostat
performed protective operation.
Low-pressure Ps detected operation
lower than 0.02MPa.
The operating compressor detected
oil shortage continuously for 2 hours.
