Operation
• During the second hour following the initiation of
Sleep mode, the temperature automatically increases
by another 2 °F (1 °C). Conversely, in Heat Pump
mode, the setpoint decreases another 2 °F (1 °C).
Dry (dehumidification) mode
The Dry mode provides mild dehumidification for room
temperatures above the setpoint and when additional
cooling is not required.
1. Press and release the Mode icon until the Dry (DR)
mode displays.
The Mode icon illuminates steadily at 100%
brightness.
The LED display shows DR for five seconds and then
alternates between DR and the temperature display
every five seconds.
All unselected icons illuminate at 50% brightness.
2. Press the ( + / ) icon to set the temperature. The
–
( + / ) icon illuminates at 100% brightness during
–
the selection, then remain at 50% brightness after
releasing the button.
3. To change the fan speed, select a mode other than
the Dry mode. The default fan speed is set to Low
(regardless of fan speed selection).
When the Dry mode is active:
• The temperature is set to the desired setpoint and the
compressor cycles on and off at approximate intervals
of six minutes to extract moisture from the air while
not lowering the room temperature. Dry mode is not
a substitute for a standalone dehumidifier.
• The AC will not dehumidify if the room temperature
is below 64 °F (18 °C). The minimum setpoint is
65 °F (18 °C).
• If the setpoint falls below 65 °F (18 °C), the LED
display flashes DR to indicate the temperature is
below the necessary threshold.

set point (above for cooling or below for heating).
The fan is controlled automatically to help retain the
setpoint.
• The setpoint temperature displays rather than the
