10-8-4. Remote Controller Selector Switch
Setting
Remote controller selector switch
• If two indoor units are installed in the same room
or adjoining rooms, the second unit can inadvert-
ently receive a remote controller signal and start
operation when operating the first unit. This can be
prevented by setting one of the indoor units and
the corresponding remote controller to the B
setting (the A setting is the default setting).
1. Setting the selector switch on the main unit
• Remove the front panel, and then set the
selector switch to “B”.
• After making the switch setting, remount the
front panel.
2. Setting the remote controller
1) Slide open the remote controller cover and
remove the batteries.
2) Cut the jumper wire inside the battery
compartment using nippers.
• The jumper wire should not remain in
contact after being cut. Also, be careful
not to let plastic scraps, jumper wire
cuttings or other debris enter the inside of
the remote controller.
3) Insert the batteries. “B” appears in the
remote controller display.
3. Check that the indoor unit can be operated by
the modified remote controller.
