OPERATION
Sequence of Operation
2. Dry mode
While selected to Dry mode, AC works at set temperature to 44.6°F for 3 minutes. After that the set temperature change to be
RT 3.6°F, the compressor works as cooling mode, and indoor fan motor operates at low speed.
The fan speed can not be changed while in dry mode, but the air direction can be adjusted.
3. I FEEL Mode
3.1 The operation mode and initial ST are generated by the Initial RT, and the operation mode is enabled once unless
AC is switched off and powered on again. While I FEEL is changed from other mode , the AC will operate based on the
RT temperature judgement.
3.2 PCB with Auto Restart Function, while power on again,
a). With Auto Restart Function activated, AC runs according to the temperature judgement.
b). If without Auto Restart Function or the function is shut off, AC works on stand by.

When AC works in Dry mode after judgement, the display temperature ranges from 60°F to 80°F, and the set temperature ranges from
41°F to 87.8°F.
When AC works in Fan mode, the set temperature is xed to 73.4°F, and displays room temperature.
In I FEEL mode (I FEEL cooling or heating), and the PCB receives instructions of temperature adjustment as increasing or decreasing
from remote control, the unit sets ST as the current room temperature±1°F.
(in heating mode, the RT need to be compensated), I FEEL temperature adjusts : ±3.6°F and buzzer responds but controller
takes no action. The set temperature range is from: 60.8°F -87.8°F.
Only works on Cooling or Heating of I FEEL mode, the unit has above temperature control process. In I FEEL Dry or Fan
mode, the buzzer responds, but does not have control of any other operation.
