5 Modes and Operating Conditions
5.1 Terms and Definitions
TA: Ambient indoor temperature.
TS: Set temperature.
5.2 Cooling Mode (Blue Light)
The cooling temperature can be set from 64 to 90℉.
The timer function works in cooling mode.
The compressor will run when the difference between the set temperature and the actual ambient room
temperature conforms to the chart below:
When TA≤TS (for 1 minute) the compressor turns off.
When TA>TS+2℉ the compressor turns on.
5.3 Fan Only Mode (Green Light)
If the temperature can’t be controlled by the selected mode and the room ambient temperature is shown
on the display the unit will default to fan only mode.
The readout can only display a temperature of 32 to 99 ℉ (0 to 37℃.) lf the temperature is out of that
range the display will show LO or HI.
The Timer function works in fan only mode.

5.4 Dehumidify Mode (Yellow Light)
In this mode, the air conditioner will operate as a dehumidifier. Because the conditioned space is closed
or sealed, some degree of cooling will continue to occur.
If the room temperature is below 77ºF, the fan will always run on low speed while in dehumidify mode.
If you do not use the exhaust hose in Dehumidifying mode, you must manually drain the water from the
unit. Additionally, the ambient temperature in the room will probably rise by a few degrees if you do not
use the exhaust hose.
You will be not be able to change the thermostat temperature or fan speed while in dehumidify mode.
5.5 Automatic Mode
In Automatic mode, the unit will cool or dehumidify depending on the ambient temperature.
As the temperature in the room changes, the mode and fan speed will change automatically.
The front panel lights will change depending on the mode.
5.6 Overflow Prevention
When water is detected in the reservoir for 3 seconds overflow prevention will occur.
The water light turns on.
5.7 Compressor Protection
If power is interrupted, the compressor will only restart after a 3 minute delay.
