To Select the Operating Mode:
To choose the operating mode, press the Mode button . Each time you press the button a
mode is selected in a sequence that goes from Auto, Cool, Dry, to Fan. The indicator light
adjacent to the mode label will be illuminated and remain on once the mode is selected.
To Operate in Auto Mode:
 When you set the unit to “Auto” mode it will automatically select cooling or fan only
operation depending on the temperature selected and the current room temperature.
 Once the temperature you selected is achieved, the unit will automatically maintain the
room temperature.
 In this mode the fan speed cannot be adjusted. It will start automatically at a speed
calibrated to the actual room temperature.
To Operate in Fan Only Mode:
 Use this function only when cooling is not desired, such as for room circulation or to
exhaust air (remember to open the vent). You can choose any speed you prefer.
 In this mode, the display will show the actual room temperature as in the cooling mode.
 In Fan Only mode, the temperature is not adjusted.
To Operate in Dry Mode:
 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.
To Use the Energy Saver Feature:
To start the Energy Saver, press the Energy Saver button . This feature is available on
“Cool”, “Dry”, and “Auto”. The fan will continue to run for 3 minutes after the compressor
shuts off. The fan then cycles on for 2 minutes at 10 minute intervals until the room
temperature is above the set temperature, at which point the compressor turns back on and
cooling starts.
To Use the Timer (Auto Start/Stop) Feature:
 When the unit is on or off, press the Timer button and the “Timer On” indicator light
illuminates. It indicates that the Auto Start program is initiated.
 To switch the timer off press the Timer button again and the “Timer Off” indicator
light illuminates. It indicates that the Auto Stop program is initiated.
 Press or hold the Up or Down button to change the Auto Time by ½ hour
increments up to 10 hours, or 1 hour increments thereafter up to 24 hours. The control
will count down the time remaining until start.
 The selected time will register in five (5) seconds and the system will automatically
revert back to display the previous temperature setting or room temperature when the
unit is on.
Note: When the unit is off there is no display.

13
To Use the Check Filter Feature:
This feature is a reminder to clean the Air Filter for more efficient operation. The LED light will

Filter indicator, simply clean the filter as indicated in the maintenance section of this manual
and press Check Filter button .
Digital Display:
Displays the set temperature in °C or °F and the Auto-Timer settings. While on Fan Only
mode it shows the room temperature.
Air Louvers
The 4-way air directional louvers allow you to direct the air flow Up, Down, Left, and Right
throughout the room as needed. To adjust the air directional louvers side to side use the center
handles as you move side to side.
Additional Tips:
The “Cool” mode has an automatic three (3) minute timed delay start if the unit is turned off and
on quickly. This prevents overheating of the compressor and possible circuit breaker tripping.
The fan will continue to run during this time.
The control is capable of displaying the temperature in degrees Fahrenheit or degrees Celsius.
To convert from one to the other, press and hold the Up and Down Temp/Timer buttons at the
same time for three (3) seconds
