6.1.2 Basic Functions
Once energized, the compressor should in no way be restarted unless after 3-minute time interval at least. For the first
energization, the compressor will be started without 3-minute lag. Once started, the compressor will not be stopped
within 6 minutes with the change of room temperature.

After startup of unit under or to cooling mode from other mode when ambient temp 30 , or amibient temp is 3 higher
or much higher than setting temp , indoor fan after startup of compressor will be forced to run at super high speed and
then switch into setting speed after 10 min or after temp reaches so that the unit stops.Once indoor fan runs at setting
speed after startup of compressor, it won't be forced to run at super high speed.Under this mode, switchover valve is
de-energized and temp range is 16-30
6.1.2.1.2 Pretection
Antifreezing Protection
If it is detected that the system is under antifreeze protection,E2 will be displayed, the compressor and outdoor fan
will be stopped, and the indoor fan will run at preset speed. When antifreeze protection is released and the compressor
has been stopped for 3 minutes,LCD display will resume, and the unit will resume its original operating status.(Buttons are
not shielded during defrosting protection.)
Overcurrent Protection
If it is detected that the system amperage exceeds the specified value(about 22 A), the unit will stop when indoor ambient
temp reaches setting temp.If the compressor has been stopped for 3 minutes and it is detected that the system's current
resumes normal, the unit will resume original running state.If protection time is over 6, LED will blink and display E5, in which case,
original running state can't resume, so it is needed to press ON/OFF button to stop and then repress this button to restart the
unit.
