When Auto mode is fi rst selected, the fan will operate at a low speed for
about a few minutes, during which time the indoor unit detects the room
conditions and selects the operation mode.
When the air conditioner has adjusted your room's temperature to near
the thermostat setting, it will begin monitor operation.
In the monitor operation mode, the fan will operate at a low speed. If the
room temperature subsequently changes, the air conditioner will once
again select the appropriate operation (Heating, Cooling) to adjust the
temperature to the value set in the thermostat.
If the mode automatically selected by the unit is not what you wish,
select one of the mode operations (Heating, Cooling, Dry, Fan).
■ Cooling mode
Use to cool your room.
NOTES:
• Set the temperature lower than the current room temperature,
otherwise, the fan alone will operate.
• The indoor unit fan may stop from time to time because of the Fan
control for energy saving (refer to page 3).
■ Dry mode
Use for gently cooling while dehumidifying your room.
NOTES:
• You cannot heat the room.
• Set the temperature lower than the current room temperature,
otherwise, the operation will not operate.
