1) When the “Automatic”

operation mode is
selected,  “Automatic”
does not change by
pressing the fan speed
select button.

2) The room temperature

setting is not displayed.

3) Pressing the room

temperature control button
develops transmit mark
“        ” and sounds a
receive sound but does
not display the room
temperature setting.

Q20

Wireless remote controller

The room temperature
sensing thermistor in the
indoor unit detects the room
temperature and, according
to the particular temperature,
automatically performs
“Cooling” or “Dehumidifying”
operation.
The value indicated not at an
“Automatic” but manual
operation is not the actual
room temperature but the
room temperature setting.

When the room temperature
setting is “16”, pressing the
room temperature control
button  “ V ” causes no
transmission. At “32”,
pressing  “      ” causes no
transmission either.

Q21

The room temperature is
settable within the range of
16 - 32 and not beyond.

A21

The timer cannot be set.

Q22

Is the current time set?
The timer cannot be set
unless the clock is adjusted
correctly.

A22

V

The current time disap-
pears soon.

Q23

The current time disappears
soon and the timer settting
indication takes a
precedence.

A23

When setting the current time,
its indication blinks for
approximately 3 minutes.

1)

When the operation mode
is  “Automatic”, the fan
speed is automatically
fixed to “Automatic”.

2)

At an “Automatic”
operation, the room
temperature setting is not
displayed.
The room temperature is
automatically set as
follows.

At cooling

Set at 27

°

C.

At dehumidifying

Set to a temperature
slightly lower than the
room temperature.

At heating

Set at 23

°

C.

3)

At an “Automatic”
operation, the room
temperature setting is not
displayed.
However, every pressing
“      ” or “ V ” button
changes 1

°

C within the

range of:
27

±

3

°

C when cooling,

23

±

3

°

C when heating.
