OPERATING TIPS
Instructions relating to heating (*) are applicable only to "HEAT & COOL MODEL" (Reverse Cycle).
Mode operation
AUTO (in COOLING model):
When AUTO (automatic changeover) operation fi rst selected, the fan will operate at very low speed for about a few
minutes, during which time the indoor unit detects the room conditions and
selects the proper mode.
Room temperature is higher than the defi ned temperature in temperature setting
→ Cooling mode or dry mode
Room temperature is close to or lower than the defi ned temperature in tem-
perature setting → Monitor operation
When the indoor unit has adjusted your room's temperature to near the tem-
perature setting, it will begin monitor operation. In the monitor operation mode, the fan will operate at low speed. If the
room temperature subsequently changes, the indoor unit will once again select the appropriate operation (cooling) to
adjust the temperature to the value set in the temperature setting.
If the mode automatically selected by the unit is not what you wish, select one of the mode operation (COOL, DRY,
FAN).
AUTO [in HEAT & COOL (Reverse Cycle) model]:
When AUTO (automatic changeover) is selected, the air conditioner selects the appropriate operation mode (cooling
or heating) according to your room's present temperature.
When AUTO (automatic changeover) operation fi rst selected, the fan will operate at low speed for about a few minute,
during which time the indoor unit detects the room conditions and selects the proper operation mode.
Room temperature is higher than the defi ned temperature in temperature
setting → Cooling mode or dry mode
Room temperature is close to the defi ned temperature in temperature setting
→ Determined by outdoor temperature
Room temperature is lower than the defi ned temperature in temperature
setting → Heating 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 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 operation (HEAT, COOL,
DRY, FAN).
HEAT*:
Use to warm your room.
When heating mode is selected, the air conditioner will operate at very low
fan speed for about 3 to 5 minutes, after which it will switch to the selected
fan setting. This period of time is provided to allow the indoor unit to warm
up before beginning full operation.
When the room temperature is very low, frost may form on the outside unit,
and its performance may be reduced. In order to remove such frost, the unit
will automatically enter the defrost cycle from time to time. During automatic
defrosting operation, the heat operation will be interrupted.
After the start of heating operation, it takes sometime before the room gets
warmer.
COOL:
Use to cool your room.
DRY:
Use for gently cooling while dehumidifying your room.
You cannot heat the room during dry mode.
During dry mode, the unit will operate at low speed; in order to adjust room
humidity, the indoor unit's fan may stop from time to time. Also, the fan may
operate at very low speed when adjusting room humidity.
The fan speed cannot be changed manually when dry mode has been se-
lected.
FAN:
Use to circulate the air throughout your room.

Heating
During heating mode:
Set the thermostat to a temperature setting
that is higher than the current room tem-
perature. The heating mode will not operate
if the thermostat is set lower than the actual
room temperature.
During cooling/dry mode:
Set the thermostat to a temperature setting
that is lower than the current room tem-
perature. The cooling and dry modes will
not operate if the thermostat is set higher
than the actual room temperature (in cooling
mode, the fan alone will operate).
During fan mode:
You can not use the unit to heat and cool
your room.
