10-5-4. If the air conditioner operates
incorrectly
• If two indoor units are installed in the same room
or adjoining rooms, when the user tries to operate
only one unit, both units may receive the same
remote controller signal and operate. This can be
prevented by changing one of the indoor units and
remote controllers to setting “B”
(The default setting for both units is “A”).
• If the indoor unit and remote controller settings
are different, the remote controller signal is not
accepted.
1. 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.
2. Setting the unit
Push the RESET button to start automatic
operation.
3. Push the button of the remote controller
that was set in step 1 to stop the air
conditioner.
(This operation will change the setting to “B”.)
4. Check that the remote controller operates the
indoor unit.
