In AREA setting, the horizontal air

ﬂow direction changes automatically

according to the detection of i-see

Sensor which detects the ﬂoor/wall

temperature to air-condition the room

evenly.

i-see control operation

i-see Sensor constantly measure

ﬂoor/wall temperature to automatically

adjust to the set temperature by

estimating the temperature actually

perceived by a person inside the room

(“sensible temperature”).

●The air coverage is the figure up to the

position where the air speed is 1 ft./

sec., when air is blown out horizontally

from the unit properly at the High speed

position.

The coverage should be used only

as a general guideline since it varies

according to the size of the room and

furniture arranged inside the room.

7-1. TIMER SHORT MODE

For service, set time can be shortened by short circuit of JPG and JPS the indoor electronic control P.C. board.

The time will be shortened as follows. (Refer to 9-7.)

Set time: 1-minute 1-second

Set time: 3-minute 3-second (It takes 3 minutes for the compressor to start operation. However, the starting time is

shortened by short circuit of JPG and JPS.)

7-2. P.C. BOARD MODIFICATION FOR INDIVIDUAL OPERATION

A maximum of 4 indoor units with wireless remote controllers can be used in a room.

In this case, to operate each indoor unit individually by each remote controller, P.C. boards of remote controller must be

modified according to the number of the indoor unit.

How to modify the remote controller P.C. board

Remove batteries before modification.

The board has a print as shown below:

The P.C. board has the print “J1” and “J2”. Solder “J1” and “J2” according to the number of indoor unit as shown in Table 1.

After modification, press the RESET button.

NOTE: For modification, take out the batteries and

press the OPERATE/STOP (ON/OFF) but-

ton twice or 3 times at first.

After finish modification, put back the bat-

teries then press the RESET button.

How to set the remote controller exclusively for particular indoor unit

After you turn the breaker ON, the first remote controller that sends the signal to the indoor unit will be regarded as the remote

controller for the indoor unit.

The indoor unit will only accept the signal from the remote controller that has been assigned to the indoor unit once they are

set.

The setting will be cancelled if the breaker has turned OFF, or the power supply has shut down.

Please conduct the above setting once again after the power has restored.
