6. How to perform zone registration
To operate the central controller properly, zone registration is required after
finishing the test run (and after setting all indoor unit addresses) using one of
the following methods.
Procedures common to all units
1. Connect the U1/U2 terminals to the relay connectors of the U3/U4 terminals
inside the outdoor unit (central unit).
2. Leave the SW30-2 switch on the outdoor unit (central unit) interface board at
the ON position for one system only, and set all the other switches to OFF.
(For details on the SW-30 position, refer to the wiring diagram provided with
the outdoor unit.)
(a) Zone registration using the remote controller (RBC-AMT21E)
Refer to page 16
(b) Zone registration using the central controller (TCB-SC642TLE)
Refer to page 17
(c) Automatic zone registration using the central controller (TCB-SC642TLE)
Refer to page 18
For methods (a) and (b), you should make a zone registration table manually
before performing the registration as shown on the page 15.
For method (c), zone registration is executed automatically, proceeding from
small indoor unit address and small central addresses to larger numbers in
numerical order. For example:
For methods (b) and (c)
These methods are not supported by the RAV models.
For RAV models, initiate the zone registration described in (a).
Wait at least 10 minutes after the power has been turned on before starting to
set the addresses.
It may take up to 10 minutes (although it usually takes 3 minutes) to establish
initial communication between the indoor and outdoor units. If the addresses
are set before this communication is completed, the central address may fail to
be set in some of the indoor units.

NOTE
1. An indoor unit address is assigned to each indoor unit during automatic
address operation. Each indoor unit address combines an R.C. address
and indoor unit number as follows:
This address is displayed on remote controller for UNIT No. when the UNIT
button is pressed.
2. The central address represents the zone and group number. These
addressed are assigned in ascending numerical order.
3. For details on how to set the addresses when the TCC-LINK adapter is
connected for central control, refer to these instructions and to the
installation instructions of the TCC-LINK adapter.
