6. Plug into a grounded 3-prong outlet and press “Reset” on the power cord supply. Lastly, press the on/off button to power on the unit.

Operation

Control Panel Operation

Operating Modes:

Auto Mode:

• When you set the unit to Auto mode it will automatically select Cooling, Heat, 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.

Cool Mode:

• When the unit is set to “Cool” mode it will cool the room to maintain the desired set temperature.
• When the desired temperature has been reached, the unit will automatically maintain the temperature.
• Press Up and Down buttons to adjust the desired temperature and press the Fan button to adjust fan speed.

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.
• In Fan Only mode, the temperature is not adjustable.

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.
• The fan speed is set to Low automatically.

Heat Mode:

• When the unit is set to “Heat” mode, it will heat the room to maintain the desired set temperature.
• When the desired temperature is reached, the unit will automatically maintain the temperature.
• The fan speed is not adjustable in heat mode

Note: Heat function is intended to provide supplemental heating in addition to an existing heat source. The heat function has a lower BTU rating than the cool mode and therefore does not treat the same quire footage. The maximum heating capacity of the unit is 15° F above the ambient room temperature

Additional Tips:

To Use the Timer (Auto Start/Stop) Feature:
Setting an Auto Start: While the unit is off, press the Timer button ONCE. The timer on indicator will illuminate. You then have 3-5 seconds to set the start time. Use the Up or Down buttons to change the time by 1/2 hour increments up to 10 hours or 1 hour increments up to 24 hours. The selected time will display for 5 seconds and then revert to the previous display.

Setting an Auto Stop: While the unit is off, press the Timer button TWICE. The timer off indicator will illuminate. You then have 3-5 seconds to set the stop time. Use the Up or Down buttons to change the time by 1/2 hour increments up to 10 hours or 1 hour increments up to 24 hours. The selected time will display for 5 seconds and then revert to the previous display. Turning the unit on or off at any time, or adjusting the timer setting to 0.0 will cancel the timer program.
Digital Display:

• Displays the set temperature in °C or °F and the Auto-Timer settings. While operating in Fan Only mode, it shows the current room temperature.
• To switch between °C and °F, press and hold the Up and Down Temp and Timer buttons at the same time for three (3) seconds.
