If it is detected that the system amperage exceeds the specified value(about 22 A), the unit will stop when indoor ambient
temp reaches setting temp.If the compressor has been stopped for 3 minutes and it is detected that the system's current
resumes normal, the unit will resume original running state.If protection time is over 6, LED will blink and display E5, in which case,
original running state can't resume, so it is needed to press ON/OFF button to stop and then repress this button to restart the
