Features

To Adjust Fan Speeds

Press the Fan Speed button to select the FAN Speed in four steps - Auto, Low, Med, or High. Each time the button is pressed, the fan speed mode is shifted.

For some models, the fan speed can not be adjusted under HEAT mode. In DRY mode, the fan speed is controlled at low automatically.

Sleep

Press the Sleep button to initiate the sleep mode. In this mode the selected temperature will increase (cooling) or decrease (heating) by 2°F / 1°C 30 minutes after the mode is selected. The temperature will then increase (cooling) or decrease (heating) by another 2°F / 1°C after an additional 30 minutes.

This new temperature will be maintained for 7 hours before it returns to the originally selected temperature. This ends the Sleep mode and the unit will continue to operate as originally programmed. The Sleep mode program can be cancelled at any time during operation by pressing the Sleep button again.

Check Filter

Press the Filter button to initiate this feature. This feature is a reminder to clean the air filter for more efficient operation.

The LED (light) will illuminate after 250 hours of operation. To reset after cleaning the filter, press the Filter button and the light will go off.

Eco - Energy Saver

Press the Eco button to initiate this feature. This feature is available on COOL, DRY, AUTO, (only AUTO-COOLING and AUTO-FAN) modes. 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 time the compressor turns back on and Cooling starts.

To Select the Operating Mode

To choose 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, Heat (on some models) and Fan only. The indicator light above will be illuminated and remain on once the mode is selected.

The unit will initiate the Energy Saver function under Cool, Dry, Auto (only Auto-Cooling and Auto-Fan) modes.

To Operate on Auto Feature:

■ When you set the air conditioner in AUTO mode, it will automatically select cooling, heating (on some models) or fan only operation depending on what temperature you have selected and the room temperature.

■ The air conditioner will control room temperature automatically to the temperature set point.

■ In this mode, the fan speed cannot be adjusted, it starts automatically at a speed according to the room temperature.

To Operate on Fan Only:

■ Use this function only when cooling is not desired. You can choose any fan speed you prefer.

■ During this function, the display will show the actual room temperature, not the set temperature in the cooling mode.

■ In Fan only mode, the temperature is not adjustable.

To Operate on Dry Mode:

■ In this mode, the air conditioner will generally operate in the form of a dehumidifier. Since the conditioned space is a closed or sealed area, some degree of cooling will continue.

Timer: Auto Start / Stop

■ When the unit is on or off, first press the Timer button, the TIMER ON indicator light illuminates. It indicates the Auto Start program is initiated.

■ When the time of TIMER ON is displayed, press the Timer button again, the TIMER OFF indicator light illuminates. It indicates the Auto Stop program is initiated.

■ Press or hold the UP or DOWN button to change the Auto time by 0.5 hour increments, up to 10 hours, then at 1 hour increments up to 24 hours. The control will count down the time remaining until start.

■ The selected time will register in 5 seconds, and the system will automatically revert back to display the previous temperature setting or room temperature when the unit is on. (When the unit is off, there is no display.)

■ Turning the unit ON or OFF at any time or adjusting the timer setting to 0.0 will cancel the Auto Start/Stop timed program.

Additional Features

The “Cool” circuit has an automatic 3 minute delayed 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.

There is a 2 second delay for the compressor to stop when selecting FAN ONLY/HEAT. This is to cover the possibility of having to roll through to select another mode.

The control will maintain the set temperature within 1°F between 62°F and 86°F in cool or heat mode (on some models).

After a power outage, the unit will remember last setting and return the unit to that setting when power is restore.

Air Direction

Air directional louvers control air flow direction. The louvers will allow you to direct the air flow up or down and left or right throughout the room as needed until the desired left/right direction is obtained. Pivot horizontal louvers until the desired up/down direction is obtained.

Ventilation

To open the ventilation port, remove the adjustable air discharge louvers by gently pulling forward the right end until it is released from the pivot point. Shift the louvers to the right to release the left end from its pivot point. To open the ventilation port, pull the lever forward. The lever will lock in place. To replace the air discharge louvers, reverse the above procedure

Remote Wall Thermostat (Heat/Cool models only)

All heat/cool models are capable of being controlled by a 24 VAC remote wall thermostat. The thermostat control connection board is located behind a metal cover on the right side of the metal chassis cover. To open the cover, remove the Phillips head screw and lift from the slots at the bottom. To properly connect the wiring from a remote wall thermostat, follow these steps:

1. Order the 8-pin connector from GE Appliances Service. Call 1-800-626-2002 and order WP26X24981. A connector is required for each unit being controlled by a wall thermostat
2. Install the remote thermostat according to the directions included with it.
3. Using wire nuts included with the 8-pin connector, connect the wiring from the wall thermostat per the following; (Proper connection of the wiring is critical. Improper hookups could result in damage to the air conditioner components and may not be covered by the product warranty) After properly making the wire nut connections, wrap the 7 connectors together with electrical tape and push them into the lower right corner of the control box opening to keep them out of the way.
