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.

11. Addresses
19
(EN)
ENGLISH
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 flexible
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 (CZ-RWSK2). (See page 20.)
• 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-RWSD2N/CZ-RWST3N is of receivers (inside the indoor unit); CZ-
RWSL2N is of an operation panel (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*2, 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.
*2CZ-RWSL2N is an operation panel (indoor unit).
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.
