distance should be used only as a guide. It depends on battery strength.
• Makesurenothingisbetweentheremotecontrollerandthereceiverthat
could block the signal.
• Donotleavetheremotecontrollerindirectsunlight,wherethewindfrom
the air conditioner can blow directly on it, or near any other heat source.
• Takecarenottodrop,throw,orwashtheremotecontrollerwithwater.
• Thesignalfromtheremotecontrollermaynotbereceivedinroomswith

Wall Mount Use
• Press from the location
you wish to mount the remote
controller and make sure the
signal is received properly.
• Pulltheremotecontroller
forward to remove it.
10. For Best Results
Do not get the remote controller too far away from the receiver.
This may cause a malfunction.
Be sure to keep the remote controller in the same room as the receiver.
Point the remote controller at the receiver.

11. Addresses
17
(EN)
In both multi and single unit installations, when more than one indoor units
are installed in the same room with a compatible wireless remote controller,
addresses can be set up to avoid crosstalk.
By setting the address switches on the receivers and matching them with the
number of addresses on the remote controller, up to six indoor units can be
controlledseparatelywiththeremotecontroller.(Whenusingunitsinaexible
combination or operating multiple units simultaneously, they cannot be
controlled individually as they are operated at the same time.)
There are separate address settings: receiver addresses for the receivers*1,
and transmitter addresses for the remote controller.
For more information, please contact the distributor where the product was
purchased.
• Thesettingprocedureisdifferentforindoorunit.(Seepage18.)
• Thesesettingsaresavedinnonvolatilememoryintheremotecontroller,so
even when its batteries are changed, the settings do not have to be made
again.
*1CZ-RWSD2U/CZ-RWST2U is of receivers (inside the indoor unit).
Checking Addresses
When you press on the remote controller, its current address appears on
the display. If this address corresponds to the address of a receiver, the
buzzer sounds. (If it is on ALL, the buzzer will always sound.)
If it is on ALL, it can be operated regardless of receiver addresses. Point the
remote controller at the receiver you wish to operate and transmit.
Matching Up Addresses
Setting Remote Controller Addresses
1. If you press and at the same time, will blink.
2. While holding down, every time you press , it cycles
from ALL123…6ALL.
Set it to the receiver address switch of the indoor unit you wish to operate.
3. When you release , the address that was displayed is set.
When you do this, if it corresponds to the receiver’s address setting, the
buzzer sounds.
