About Mode Operation

AUTO:
COOLING MODEL

When the room temperature is 4 

°

F

higher than the set temperature, the
mode will switch between Cooling and
Drying.

During the Drying mode operation, the
FAN setting should be switched to LOW
for a gently cooling effect during which
the fan may temporarily stop rotating.

If the mode automatically selected by the
unit is not satisfactory, see page 7 for in-
structions on changing the mode setting
(COOL, DRY, FAN).

AUTO (* AUTO CHANGEOVER):
HEAT & COOL MODEL (Reverse cycle)

When AUTO CHANGEOVER is selected, the air conditioner selects the appropri-
ate operation mode (Cooling or Heating) according to your room’s present tem-
perature.

When AUTO CHANGEOVER is first selected, the fan will operate at very low speed
for about one minute while the unit determines the current conditions of the
room and accordingly selects the proper operation mode.

When the air conditioner has adjusted your room’s temperature to near the ther-
mostat 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, Cool-
ing) to adjust the temperature to the value set in the thermostat. (The monitor
operation range is 

±

°

F relative to the thermostat setting.)

If the mode automatically selected by the unit is not satisfactory, see page 7 for
instructions on changing the mode setting (HEAT, COOL, DRY, FAN).

*Heating:

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 set-
ting. This period of time is provided to allow the indoor unit to warm up before
begin 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 De-
frosting operation, the OPERATION indicator light (red) will flash, and the heat
operation will be interrupted.

Cooling:

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 detecting room humidity.

The fan speed cannot be changed manually when Dry mode has been selected.

Fan:

Use to circulate the air throughout your room.

* 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 set-
ting that is lower than the current room
temperature. 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 oper-
ate).

During Fan mode:

The heat and cool functions of this unit
cannot operate in the Fan mode.
