1. Setting method
Assign the same pair number to the wireless remote controller as that of the
indoor unit. If not doing so, the remote controller cannot be operated. Refer to
the installation manual that came with the wireless remote controller for how to
set pair numbers of wireless remote controllers.

2. Setting example
(1) To use the units in the same room
[Fig. 8-4-3] (P.6)
① Separate setting
Assign a different pair number to each indoor unit to operate each indoor unit
by its own wireless remote controller.
[Fig. 8-4-4] (P.6)
② Single setting
Assign the same pair number to all the indoor units to operate all the indoor
units by a single wireless remote controller.
[Fig. 8-4-5] (P.6)
(2) To use the units in different rooms
Assign the same pair number to the wireless remote controller as that of the
indoor unit. (Leave the setting as it is at purchase.)
3) How To Install

Ⓒ Signal Receiving Unit
(1) Select the installation site.
The following must be observed.
① Connect the signal receiving unit to the indoor unit with the supplied remote
controller wire. Note that the length of the remote controller wire is 5 m (16
ft). Install the remote controller within the reach of the remote controller wire.
② When installing on either the switch box or the wall, allow space around the
Signal Receiving Unit as shown in the figure in [Fig. 8-4-6].
③ When installing the Signal Receiving Unit to the switch box, the Signal
Receiving Unit slipped downward for 6.5 mm (1/4 inch) as shown in the
figure in [Fig. 8-4-6].
④ Parts which must be supplied on site.
Switch box for one unit
Thin-copper wiring pipe
Lock nut and bushing
⑤ The thickness of the ceiling to which the remote controller is installed must
be between 9 mm (3/8 inch) and 25 mm (1 inch).
⑥ Install the unit on the ceiling or on the wall where the signal can be received
from the wireless remote controller.
The area where the signal from the wireless remote controller can be
received is 45° and 7 m (22 ft) away from the front of the signal receiving
unit.
⑦ Install the signal receiving unit to the position depending on the indoor unit
model.
⑧ Connect the remote controller wire securely to the order wire. To pass the
remote controller wire through the conduit, follow the procedure as shown in
Fig. 8-4-8.
[Fig. 8-4-8] (P.7)
Ⓐ Fix tightly with tape.

Note:
• The point here the remote controller
on the indoor unit model.
Take into account that the remote controller wire cannot be extended when
selecting the installation site.
• lf the Signal Receiving Unit is installed near a fluorescent lamp specially
inverter type, signal interception may occur.
Be careful for installing the Signal Receiving Unit or replacing the lamp.
2. Installation on the switch box or on the wall
(1) Use the remote controller wire to connect it to the connector (CN90) on
