Basic Operation Modes:
AUTO / COOL / DRY / HEAT (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.
DRY Mode:
The temperature is regulated while dehumidifying by
intermittently switching the COOL or FAN-ONLY 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. 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.
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.
To achieve optimal performance, please note the
following:
DO NOT put any objects near the air inlets/outlets.
Doing this would impair performance and could
cause the unit to shut down.
• Adjust the airflow direction correctly, so that it is
not towards people or at an extreme angle.
• Adjust the temperature to achieve moderate
comfort levels. An excessively low or high
temperature setting wastes energy.
• Keep windows and doors closed, as this will
improve performance.
• Limit energy usage (run time) using the TIMER
function.
• Inspect the air filters periodically, and clean them
as needed.
