Operating Instructions

Basic Operation Modes:
AUTO / COOL / DRY / HEAT / FAN (Model Dependent).
AUTO Mode:
When you set the unit in AUTO mode, it will automatically select COOL, HEAT, or FAN-ONLY mode
depending on the set temperature and the room temperature. The unit will control the room temperature
automatically, according to the temperature you set the unit to.
COOL Mode:
When unit is set in COOL mode, it puts the system into the cooling operation. It will continually cool the room
until the it reaches the temperature set on the display.
DRY Mode:
The temperature is regulated while dehumidifying by intermittently switching the COOL or FAN modes on and
off. The fan speed is set to LOW.
HEAT Mode:
The unit is a heat pump by design. By reversing the air conditioning process, it absorbs heat from the
outdoors and transfers it to the indoor unit. At the same time, heat loading of the air conditioner increases
due to larger differences between the indoor and outdoor temperature. As a result, the operating
performance and efficiency is reduced as the outdoor air temperature drops. If you feel that the heating
performance is insufficient, it is recommended that you supplement heating with other appliances.
FAN Mode:
When the unit is put into FAN mode, the HEAT or COOL modes are deactivated and only the fan operates.
The fan continually recirculates the air in the room.
Special Features & Functions:
SLEEP Mode:
The SLEEP function is used to decrease energy use while you sleep. During sleep you do not need the same
temperature settings to stay comfortable. This function can only be activated via the remote control. The
SLEEP function is not available in FAN or DRY modes. When SLEEP mode is activated, the temperature will
increase while cooling, or decrease while heating by, 2°F (1°C) per hour for the first 2 hours. Thereafter, it
keeps this new temperature for 6 hours before SLEEP mode will automatically switch off and return to the
original temperature before it was activated.
