● The selected time will register in 5 second and the system will automatically revert back to
display the previous temperature setting.
● Turning the unit ON or OFF at any time will cancel the Auto Start/Stop function.
DRY:
This mode is used to decrease the humidity in the room.
COOL:
The temperature setting are adjustable between 17 °C to 30 °C. Cooling begins automatically
when the room temperature is 1 °C above the set point, and stops when the room temperature
is 1 °C below the set point. The fan will not stop running.
HEAT:
The temperature settings are adjustable between 17 °C to 30 °C in heating mode.
The default temperature setting is 24 °C in heating mode and the fan speed is optional.
Notes: 1. When changing the temperature setting, the fan motor operates at LOW speed for
3 minutes first for compressor protection feature before heating begins.
2. When heating stops, there may be a slight delay of 30 seconds for the fan motor to
stop.
3. If the condenser temperature is below 35 °C, the fan will run in LOW speed despite
the FAN setting. If the condenser temperature is above 38 °C, the fan will run at the
FAN setting.
4. If the compressor is shut down by a malfunction, the fan will immediately shut down
with the compressor.
AUTO:
The fan motor remains on MED speed in AUTO mode. The unit will select the appropriate
operating mode from FAN, COOL or HEAT(For reverse cycle models only) based upon the
temperature difference between the actual and desired room temperature. If the actual room
temperature is 2 °C above the set point, the unit operates in cooling mode. When the actual
room temperature is not 2 °C or higher above the set point and not 2 °C or lower below the set
point, the unit will select the FAN mode. When the actual room temperature is 2 °C below the
set point, the unit will operate in HEAT mode(For reverse cycle models only).
Note: 1. If activating the SLEEP mode when the unit is operating on AUTO mode, the fan
motor will changed into LOW speed mode immediately.
SLEEP:

"SLEEP" feature. Press and hold the "SWING" keypad for 2 seconds or use the remote control
again to deactivate the "SLEEP" feature. In the Cooling mode, the cooling temperature set point
will increase 1 °C per hour after the "SLEEP" mode is selected. Two hours later, the set point
will continue at this temperature and the fan motor will remain on LOW speed. In the Heating
mode, the heating temperature set point will decrease 1 °C per hour after the "SLEEP" mode
is selected. Two hours later, the set point will continue at this temperature and the fan motor
will remain on LOW speed.This new temperature will be maintained for 7 hours, then the unit
exits sleep mode and is off. Using the "SLEEP" mode will reduce noise creating a comfortable
sleeping environment.
Note: When activating the SLEEP mode in AUTO mode, the set temperature will not change
over time.
