ADJUSTMENT (Refer to figure 4)

For adjustment the desired temperature, fan
speed and air flow direction (only for the
remote controller BRC1A51: FXC, FXF, FXH,
FXK, FXA), follow the procedure shown below.

Press the temperature setting button and set

the desired temperature.

Each time this button is pressed, the tem-
perature setting rises or lowers 1°C.

NOTE

• Set the temperature within the operation range.
• The temperature setting is impossible for fan

only operation.

Press the fan speed control button and select
the fan speed of your preference.

NOTE

• For machine protection the system may con-

trol the air flow rate automatically.

• The air flow rate may be adjusted automati-

cally depending on the room temperature or
the fan may stop immediately. This is not a
malfunction.

• It may take sometime for finishing to change

the air flow rate.
This is normal operation.

Press air flow direction adjust button.
Refer to the chapter “6-3 ADJUSTING THE
AIR FLOW DIRECTION” for details.

STOPPING THE SYSTEM (Refer to figure 4)

Press the on/off button once again.
The operation lamp goes off and the system
stops operation.

NOTE

• The fan may keep on running for about

1 minute after the heating operation stops
for removing the heat in the indoor unit.

• Do not turn off the power immediately after

the unit stops.
The system need at least 5 minutes for
residual operation of drain pump device.
Turning off the power immediately will cause
water leak or trouble.

EXPLANATION OF HEATING OPERATION

• In general, heating operation may take longer to

reach the set temperature than in cooling operation.
We recommend starting the operation which was
used before using timer operation.

• The following operation is performed in order to

prevent the heating capacity from dropping or
cold air from blowing.

Defrost operation

• In heating operation, freezing of the outdoor

unit heat exchanger increases. Heating
capability decreases and the system goes
into defrost operation.

• The airflow will be set to breeze or stop.
• If stopped, the display of the remote control-

ler shows “

”.

• Once the airflow is set to breeze or stop, the

air conditioner will return to the previous
state in approximately 10 to 15 minutes.

Hot start

• In order to prevent cold air from blowing out

of an indoor unit at the start of heating oper-
ation, the indoor fan is automatically
stopped. The display of the remote controller
shows “

”.

• The heating capacity drops as the outside tem-

perature falls. If this happens, use another heat-
ing device together with the unit. (When using the
appliances which produce open fire together, ven-
tilate a room constantly.)
Do not place appliances which produce open fire
in places exposed to the air flow from the unit or
under the unit.

• It takes some time for the room to warm up from

the time the unit is started since the unit is a hot-air
circulatory system to warm the entire room.

• If the hot air rises to the ceiling, leaving the area

above the floor cold, we recommend using the cir-
culator (the indoor fan for circulating air). Contact
your dealer for details.

6-2 PROGRAM DRY OPERATION

• The program dry function deprives the room

of moisture while the air conditioner is in inter-
mittent weak cooling operation so that the
room temperature will not become too low.

• The microcomputer automatically controls

the temperature and fan speed, so these
cannot be set using the remote controller.

• This function is not available if the room tem-

perature is 20°C or lower.

• This function does not controls the humidity.
• FXL and FXN type indoor unit can not oper-
