press the Timer button to initiate the Auto-on start program, press it again within five seconds will initiate

the Auto-off stop program. 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 system will automatically revert back to display the previous temper

ature setting if there is no operation in a five seconds period.

6.8.2. Sleep function

Press this button, the selected temperature will increase (cooling) by 1

℃

℉

30 minutes. The

temperature will then increase (cooling) by another 1

℃

℉

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.
