DEFROST Mode
The air conditioner enters the DEFROST mode according to the T3
temperature value and the T3 temperature change value range plus the
compressor running time.
During the DEFROST mode, the compressor continues to runs, the
indoor and outdoor motors stop, and the indoor unit defrost lamp
illuminates and
appears.
If any one of the following items is satisfied, the defrosting finishes and
the machine reverts to the normal heating mode.
−−−−T3 rises to be higher than TCDE1
−−−−T3 keeps to be higher than TCDE2
−−−−The machine has run for 15 minutes in defrosting mode.

The indoor fan runs under auto fan in the relevant mode. The louver
operates same as in relevant mode. If the machine switches mode
between HEATING and COOLING, the compressor stops for 15
minutes and then chooses the mode according to T1−Ts. If the setting
temperature is modified, the machine chooses the running function
again.
DRY mode
Indoor fan speed is fixed at breeze and can not be changed.
The louver angle is the same as in the cooling mode.

Touch again, within 5 seconds, to engage the Forced Cooling
Mode. In Forced Auto, forced cooling or any other operation
mode, press the touch button to turn off the unit. In the forced
operation mode, all general protections and remote control
are available.
Operation rules:

AUTO−RESTART Function
The indoor unit is equipped with the AUTO−RESTART function,
which is carried out through an auto−restart module. In the event of a
sudden power failure, the module memorizes the setting conditions
prior to the power failure. The unit resumes the previous operation
setting (not including the SWING function) automatically three (3)
minutes after the power returns.
If the memorization condition is the FORCED COOLING mode, the
unit will run in the COOLING mode for 30 minutes and turn to the
