Cause
-
Compressor start fails 42 times in succession and the
reason for the final failure is current cut.
After the compressor starts, it stops due to current cut at
less than 20 rps.
When operation is stopped by current cut at 20 rps or
higher.
When the DC voltage (DC 280 V) exceeds 350 V.
When it is judged that the power transistor was damaged
at the time the compressor started.
When it is judged that the power transistor was damaged
at the time the compressor started.
When PWM calculation results of 0% continue for 3
minutes or longer.
When PWM calculation results of 90% and an input current
lower than the set value continue for 3 minutes or longer.
When an abnormal stop occurs 3 times with automatic
recovery within 20 minutes after the outdoor unit's power
supply was turned on.
When the power supply voltage drops during operation.
When a fan speed of 75 rpm or lower continues for 30
seconds or longer.
When there is a current safe stop in current safe I mode
during cooling operation.
When there is a current safe stop in current safe I mode
during heating operation.
When there is a current safe stop in current safe II mode
during cooling operation.
When there is a current safe stop in current safe II mode
during heating operation.
When there is a current safe stop in current safe III mode
during cooling operation.
When there is a current safe stop in current safe III mode
during heating operation.
When there is a current safe stop in current safe III + 3A
mode during heating operation.
