5. Address Switches
If you are installing one indoor unit or one group of
indoor units in the same room, it is necessary for you
to assign each unit its own address so that each can
be operated by its own remote control unit. You assign
the addresses by matching the switch position of each
indoor unit with the switch position of its remote control
unit. The switch of the remote control unit is shown in
Fig. 5-1.
5-1. Finding the Address Switches
Remove the lid by sliding it off. You can see the
switches inside the battery compartment. (Fig. 5-1)
(a) Turn off the Power Switch.
(b) Remove the Grille.
(c) Remove the lid of the electrical component box.
Pull out all the connectors connected to the front
P.C.B. (for wall-mounted type only).
(d) Remove the two screws securing the mounting
plate for two P.C.B.s (front & rear)
(for wall-mounted type only).
(e) Pull out the P.C.B.s to access the address
switch locating on the rear P.C.B. (Fig. 5-2) (for
wall-mounted type only).

Switch Positions for 2 Units or 2 Groups of Units
Table 5-1 shows the positions you can use for up to 2
units or 2 groups of indoor units installed in the same
room. Two remote control units are necessary to allow
the respective units or group to be controlled indepen-
dently.
An indoor unit cannot be controlled if its remote control
unit is too far away (more than 26 ft.). If the remote
control unit does not work correctly, bring it closer to
the unit being operated and try again. There should be
no obstacles between the remote control unit and the
indoor unit. For this reason, if the remote control unit is
to be used from a fixed position, check the operation
before mounting.
