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 up to 24 hours. The control will count down the time remaining
until start.
The selected time will display for five (5) seconds and then will automatically revert back to
display the previous temperature setting or room temperature when the unit is on.
Turning the unit ON or OFF at any time or adjusting the timer setting to 0.0 will cancel the Auto
Start/Stop program.
The timer is not a permanent setting. The user must set the timer each they wish to use it.
Sleep Button
To initiate, press the Sleep button. 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 6 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 again pressing the Sleep button.
Energy Saver Button
To start the Energy Saver feature, press the Energy Saver button. This feature is available on Cool,
Dry, and Auto. The fan continues 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.
Check Filter Button
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, simply press the Check Filter button
