Control plural indoor units with one remote control
Up to 16 indoor units can be connected.
1.
Connect the XY terminal with 2 cores wire. As for the
size, refer to the following note.
2. For Packaged air-conditioner series, set the indoor
unit address with SW2 on the indoor unit PCB from
[0] to [F] so as not to duplicate.
For the shop series
For VRF series, set the indoor unit address with SW1, SW2 and SW5-2 on the indoor unit PCB from [000]
to [127] so as not to duplicate.
For the building air- conditioning and gas heat pump series
Set the indoor unit and outdoor unit numbers by manually specifying the addresses.
Use the rotary switches SW1 and SW2 provided on the indoor unit PCB (printed circuit board) to set the
indoor unit numbers so that they are not duplicated.
Master/Slave setting when using plural remote control
Up to two receivers can be installed in one indoor unit group.
Wireless remote control's operable area
1. Standard reachable area of the signal
[condition] Illuminance at the receiver: 300lux
2. Correlation between illuminance at the receiver
and reachable area of the signal in a plain view.
The drawing in the right shows the correlation
between the reachable area of the signal and
illuminance at the receiver when the remote
control is operated at 1.0m high under the
condition of ceiling height of 2.4m. When
the illuminance becomes double, the area is
narrowed down to two thirds.
3. Installation tips when several receivers are installed close
Minimum distance between the indoor units which can avoid cross communication is 5m under the condition
of 300lux of illuminance at the receiver.
Backup switch
A backup switch is provided on the receiver. Even
when the operation from the wireless remote
control lost, or control failure), still it possible
to operate as temporary means. Press the switch
directly when operating it.
1. The air-conditioner starts the operation with
the condition of Auto mode, 23°C of set
point, High fan speed and horizontal louver
position.
2. The air-conditioner stops the operation when
the switch is pressed when in operation.

How to read the 2-digit display
On the receiver of a wireless kit, a two-digit (7-segment) display is provided.
1. An indication will be displayed
for one hour after power on.
2. An indication will be displayed for 3.5 seconds after transmitting a “STOP” command from the
wireless remote control or the operation of the backup switch to stop the unit.
3. An indication appearing in (1) or (2) above will go off as soon as the unit starts operation.
4. When there are no error records to indicate, addresses of all the connected units are displayed.
5. When there are some error records remaining, the error records are displayed.
6.
Error records can be cleared by transmitting a "STOP" command from the wireless remote control,
while the backup button is pressed.
