Description
1. Purpose
This operation is to operate only one
indoor unit using one remote controller.
2. Description
When operating one indoor unit in a
situation where two indoor units have
been installed in the same room or
nearby rooms, this operation prevents the
remote controller signal from being
received simultaneously by both units,
thus preventing both units from operating.
3. Operation
The indoor unit on which the remote
controller selection has been set to B
receives the signal of the remote control-
ler also set to B.
(At the factory the remote controller
selection is set to A on all the indoor
units. There is no A setting display.)
1. Setting the remote controller
Q
Slide and open the remote controller cover and remove the
batteries.
R
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.
S
Insert the batteries. “B” appears in the remote controller
display.
* Even after the jumper wire has been cut, switching
between A and B is still possible by pushing the CHECK
button and FIX button together.
The A or B setting, which was switched by pushing the
CHECK button and FIX button together, is restored to the
setting established prior to the switching when the battery
is replaced or the RESET button is pushed.
2. Setting the unit
Push the RESET button (Indoor unit) 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.
