Note:
1. Power input restrict selection: OFF-invalid; ON-valid(≤3500W)
2. Quiet operation: If OFF, the outdoor unit will calculate and obtain the average ambient temperature of the unit within the
last 24 hours, Tao_average_24. Then compare the current ambient temperature with the ambient temperature average
Tao_average_24, and combine it with the previous ambient temperature trend to determine whether it can enter Quiet
operation (low compressor speed and low O.D. fan speed).
