*The performance drops when operating in the LOW NOISE OPERATION.
The Current Value is limited to reduce the power consumption by External Input.
During the PEAK CUT OPERATION,
"CURRENT OVERLOAD OPERATION", "ECONOMY OPERATION" and "LOW NOISE OPERATION" are effective,
and the outdoor unit operates by lowest current of them.
However, this function becomes invalid during DEFROST OPERATION.
*Percentage is rated electrical power ratio
The compressor frequency and the outdoor unit fan speed are limited to reduce the operation noise by External Input.
During the LOW NOISE OPERATION,
"CURRENT OVERLOAD OPERATION", "ECONOMY OPERATION" and "PEAK CUT OPERATION" are effective,
and the outdoor unit operates by lowest current of them.
However, during the DEFROST OPERATION, the compressor operates by the frequency for DEFROST OPERATION.
