3.6 Automatic run mode
If there is no man-machine communication function after the unit is started, the indoor fan operates at
the ultra-low fan speed for 20 seconds before selecting a run mode. The room temperature are detected
during this period to select run mode. The mode of first to run decided by following qualification:
a) When T
room
– T
set
＞
3
℃
，
it starts in the cooling mode;
b) When -3

room
– T

，
it starts in the fan mode;
c) When T

– T

＜
-3 , it starts in the heating mode.
℃
After the first run in the cooling or heating mode, the mode will be changed as the following:
a) When Troom – Tset
＞
3 , it will be changed to the cooling mode;
℃
b) When Troom – Tset
＜
-3 , it will be changed to the heating mode;
℃
c) When these conditions are not met, it will remain in the previous run mode.
When the setting temperature is changed, re-judgment will be made for the run mode according to
the descriptions mentioned above; when the compressor is halted for 10 minutes, the re-judgment will be
made for the run mode.
3.7 Indoor fan
1. When the fan speed is set to “high”, “medium” or “low” speed, the fan runs at preset speed. But if the
