FEATURE1.
FEATURES
Peak cut operation
z
Peak cut mode
Suppresses maximum capacity to perform energy-saving operation, preventing breaker tripping.
This function operates by setting a peak current value and reducing the power consumption.
* Performance drops by reducing the power consumption preferentially.
Level 1 ... Suppresses the power consumption to almost 0% by stopping the compressor.
Level 2 ... Suppresses the power consumption to 50% of the rated power consumption value.
Level 3 ... Suppresses the power consumption to 75% of the rated power consumption value.
Level 4 ... Suppresses the power consumption to the rated power consumption value (100%).

EXTERNAL INPUT & OUTPUT13.
EXTERNAL INPUT13-1.
ON/OFF of the "Low noise mode" and "Peak cut mode" functions can be specied by external
signal.
LOW NOISE MODE
The following reduces the operating sound of the outdoor unit from the normal sound. •
The air conditioner is set to the "Low noise mode" when closing the contact input of a commercial
timer or ON/OFF switch to a connector on the outdoor control PC board.
* Performance may drop depending on the outside air temperature condition, etc.
