• 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.
• 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).
English
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
operation for a while. Low airflow rate is used to
"
prevent humidity increase.
PROGRAM TIMER OPERATION
Operate in the following order.
• The timer is operated in the following two ways.
Programming the stop time (
The system stops operating after the set time
has elapsed.
Programming the start time (
The system starts operating after the set time
has elapsed.
• The timer can be programmed a maximum of
72 hours.
• The start and the stop time can be simultaneously
programmed.
