Air Conditioner Operation & Features

ECO button

(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 restarts.

MODE button

To select each of the operating modes, press Mode button. Each time you press the button, a mode

is selected in a sequence that goes from Auto, Cool, Dry and Fan. The indicator light beside the selected

mode will illuminate and remain illuminated once the mode is selected.

1.) Operation of AUTO mode:

only operation depending on the selected temperature and the room temperature.

The air conditioner will control room temperature automatically based on the temperature you

have selected.

In this mode, the fan speed cannot be adjusted and will automatically start at a speed

according to the room temperature.

the desired temperature. When COOL Mode is selected, the fan speed can be adjusted by

pressing the fan button.

3.) Operation of DRY mode:

conditioned space is a closed or sealed area, some degree of cooling will continue. In DRY mode,

the fan speed is not adjustable.

4.) To operate FAN ONLY:

Use this function only when cooling is not desired, such as when the need arises for air circulation

or as a means to exhaust stale air (on some models). Remember to open the vent during this

function, but keep it closed during cooling for maximum cooling eﬃciency. Any fan speed can be

selected in this mode.

In FAN ONLY mode, the temperature setting cannot be adjusted.

Operation of the buttons:

section further in the manual.
