If the warm air collects near 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.

When the indoor temperature exceeds the set 
temperature, the air conditioner discharges a 
gentle breeze (switches to whisper mode).

Characteristics of the program dry operation

This operation lowers the humidity without

lowering the indoor temperature. The indoor
temperature when the operation button is pressed
will be the set temperature. At this time, the airflow
rate and humidity are set automatically, so the
remote controller does not display the airflow rate

and set temperature. To efficiently lower the indoor

temperature and humidity, first lower the indoor 
temperature using the cooling operation, and
then use program dry operation. When the indoor
temperature is lowered, air discharge from the air
conditioner may stop.

If the program dry operation is used when the 
indoor temperature is low, frost is attached to the 
heat exchanger of the indoor unit. In this case, the 
system automatically switches to defrosting

PROGRAM TIMER OPERATION

If the cooling operation is used when the indoor 
temperature is low, frost adheres to the heat 
exchanger of the indoor unit.
This can decrease the cooling capacity. In this 
case, the system automatically switches to 
defrosting operation for a while.
Low airflow rate is used to prevent humidity 
increase.

When the outdoor temperature is high, it takes 
some time until the indoor temperature reaches 
the set temperature.

Characteristics of the heating operation

(1) DEFROST OPERATION

As the frost on the coil of an outdoor unit 
increase, heating effect decreases and the 
system goes into DEFROST OPERATION.

The indoor unit fan stops and the remote

 controller displays shows “

  (DEFROST/ HOT START).

After 6 to 8 minutes (maximum 10 minutes) of 
DEFROST OPERATION, the system returns to 
HEATING OPERATION.

A hissing and “Shuh” sound may be heard 
during this particular operation.

(2) HOT START

In order to prevent cold air from blowing out of 
an indoor unit at the start of heating operation, 
the indoor fan is automatically stopped. The 
display of the remote controller shows 

” (DEFROST/HOT START).

(3) OPERATION START

For ordinary heating, it will take longer for the 
room temperature to reach the set temperature 
than with cooling. We therefore recommend 
starting the unit ahead of time using the timer 
operation.

Outside temperature and heating capacity

The heating capacity of the air conditioner 
declines as the outside air temperature falls. 
In

 

such a case, use the air conditioner in

combination with other heating systems. (When a 
combustion appliance is used, ventilate the room 

regularly.) Do not use the combustion appliance 
where the air from the air conditioner is blown 
directly toward it.

PROGRAMMING TIME

Press the PROGRAMMING TIME button and 

set the time for stopping or starting the 

system.

When this button is pressed, the time 
advances by 1 hour.

When this button is pressed, the time 
goes backward by 1 hour.
