relatively humidity (relative humidity higher than 80%). Adjust the horizontal louver to
the maximum air outlet position and select HIGH fan speed.
9. Heating mode (For cooling and heating models only)
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit
during heating operation. When the outdoor temperature falls, heat drawn in by the air
conditioner decreases accordingly. At the same time, heat loading of the air conditioner
increases due to larger difference between indoor and outdoor temperature. If a
comfortable temperature can't be achieved by the air conditioner, we suggest you use a
supplementary heating device.
10. Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, when the power restores, the OPERATION indicator
on the indoor unit starts flashing. To restart the operation, push the ON/OFF button on the
remote controller. For the unit with Auto-restart feature, when the power restores, the unit
restarts automatically with all the previous settings preserved by the memory function.
