• The function of this program is to decrease the
humidity in your room with the minimum tem-
perature decrease.
• Micro computer automatically determines
TEMPERATURE and FAN SPEED.
• This system does not go into operation if the
room temperature is below 16˚C.
Refer to figure 3 on page [1]
• For cooling only type, “COOLING”, “FAN” and
“DRY” operation are able to select.

[EXPLANATION OF HEATING OPERATION]
DEFROST OPERATION

heating effect decreases and the system goes
into DEFROST OPERATION.
• The indoor unit fan stops and the remote control-
ler display shows “
”.
• After 6 to 8 minutes (maximum 10 minutes) of
DEFROST OPERATION, the system returns to
HEATING OPERATION.
Regarding outside air temperature and heat-
ing capacity
• The heating capacity of the air conditioner
declines as the outside air temperature falls. In
such a case, use the air conditioner in combina-
tion with other heating systems.
• A warm air circulating system is employed, and
therefore it takes some time until the entire room
is warmed up after the start of operation.

automatically until the temperature inside the air
conditioner reaches a certain level. At this time,

• When the warm air stays under the ceiling and
your feet are cold, we recommend that you use a
circulator (a fan to circulate the air inside the
room). For details, consult your dealer.
For programming TEMPERATURE, FAN SPEED
and AIR FLOW DIRECTION, follow the procedure
shown below.
