Sleep Operation
The SLEEP function is used to decrease energy
use while you sleep (and don't need the same
temperature settings to stay comfortable). This
function can only be activated via remote control.
Press the SLEEP button when you are ready to
go to sleep. When in COOL mode, the unit will
increase the temperature by 2°F after 1 hour, and
will increase an additional 2°F after another hour.
When in HEAT mode, the unit will decrease the
temperature by 2°F after 1 hour, and will de-
crease an additional 2°F after another hour.
It will hold the new temperature for 5 hours, then
the unit will turn off automatically.
Note:The SLEEP function is not available
in FAN or DRY mode.
