4.2.3.3 A7 Outdoor Silence Mode
Introduction:
This function is mainly used in scenarios where the user requires low ambient noise. Smart night
silence mode and forced silence mode are available.
In smart night silence mode, the highest ambient temperature during the day is automatically
determined, and then silent operation is entered after a certain duration.
To ensure low-noise operation at night. Smart night silence mode has nine options:
Silence Mode Code Noise Level
Mode 1 01
Low noise
Mode 2 02
Mode 3 03
Mode 4 04
Mode 5 05
Mode 6 06
Mode 7 07
Mode 8 08 Medium-low noise
Mode 9 09 Ultra low noise
Highest temperature during the day generally appears during 13:00 and 15:00.
In forced silence mode, the system operates in low-noise mode regardless of day or night. This mode
has three options:
Silence Mode Code Noise Level
Mode 10 10 Low noise
Mode 11 11 Medium-low noise
Mode 12 12 Ultra low noise
After a silence mode is set, the system capability will be attenuated. Therefore, the noise and the
capability need to be balanced when a silence mode is selected.
No silence is set by default, that is, "00" status.
