Basic Operation Modes:
AUTO / COOL / DRY / HEAT (Model dependent).
Auto Operation:
When you set the air conditioner in AUTO mode, it will
automatically select cooling, heating or fan-only operation
depending on set temperature and room temperature.
The unit will control the room temperature automatically,
according to the temperature point you set.
SLEEP Operation:
When selected, the temperature will increase while cooling
or decrease while heating by 1°C / 2°F per hour for the first
2 hours. Thereafter it keeps this new temperature for 6
hours before SLEEP mode switches off.
DRYING Operation:
The temperature is regulated while dehumidifying by
intermittently switching the cooling or fan-only operation on
and off. The fan speed is set to LOW.
HEATING Operation:
This unit is a heat pump by design. By reversing the air
conditioning process, it absorbs heat from 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.
Optimal Operation:
To achieve optimal performance, please note the following:
· 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 to improve
performance.
· Limit energy usage (run time) by using the TIMER
function.
· Do not put any objects near the air inlets / outlets. Doing
so would impair performance and possibly shut down
the unit.
· Inspect the air filters periodically and clean them as
needed.
