1.2.1.2 Silent mode setting
In silent mode 1 / 2 / 3 and night silent mode, the outdoor fan speed decreases gradually. In super silent mode 1 / 2 / 3 / 4,
not only the fan speed decreases gradually, but also the compressor frequency decreases gradually.

Notes:
1. Fan speed (rpm) for different fan speed index refers to Table 3-4.2 in Part 3, 4.6 “Outdoor Fan Control”.
2. If the system pressure is over 3.5MPa, the system exits silent mode automatically.
