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 tem-
perature setting → Cooling mode or dry mode
Room temperature is close to or lower than the defi ned temperature
in temperature setting → Monitor operation
When the indoor unit has adjusted your room's temperature to near the temperature setting, it will begin monitor opera-
●
tion. 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 tem-
perature setting → Cooling mode or dry mode
Room temperature is close to the defi ned temperature in tempera-
ture setting → Determined by outdoor temperature
Room temperature is lower than the defi ned temperature in tem-
perature setting → Heating mode
When the air conditioner has adjusted your room's temperature to near the thermostat setting, it will begin monitor opera-
●
tion. 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
●
selected.
FAN: Use to circulate the air throughout your room.

Heating
During heating mode:
Set the thermostat to a temperature set-
ting that is higher than the current room
temperature. 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 cool-
ing mode, the fan alone will operate).
During fan mode:
You can not use the unit to heat and cool
your room.
