This function is used when users require lower environment noises, including night-time
automatic silent mode and forcible silent mode.
For the night-time automatic silent mode, the system can automatically judges the highest
daytime environment temperature and then starts silent operations in a certain interval to
guarantee night-time low-noise operation. There are nine types of night-time automatic silent
modes for selection:
Starting the Silent Mode X Hours after the
Daytime Temperature Reaches the Highest
Stopping the Night-time Silent
Mode after Continual Operations
for Y Hours

mode
Note: The highest daytime temperature is generally in 13:00-15:00.

night-time. The forcible silent mode fails in three categories:

mode
Notes: The system capacity may fall off after the silent mode is set. Therefore, try to balance
the noise with the capacity in selecting a silent mode category. The factory setting is ―00‖.
