Smart Manager / Central Remote Control
Installation Manual
A connection example of Smart Manager system wiring is shown below.
Connection of wiring
Here is shown a connection example of Smart Manager wiring to indoor units, Energy monitoring relay interface,
Digital Input / Output relay interface and client PC.
Termination setting
• RS-485 termination: Terminate both ends of RS-485 wire; one end on the Smart Manager and the other on the
interface. The termination on the Smart Manager has been set at shipping. For the termination on the interface,
refer to the Installation Manual of the interface.
• TCC-LINK termination: Terminate it in indoor units. Do not terminate on the Smart Manager; leave it open.
Earthing the shield wire
• RS-485 cable’s shield wire: Connect it to the FG terminal.
• TCC-LINK cable’s shield wire: Do not connect it to the FG terminal. TCC-LINK cable must be earthed on the air
conditioner.
Group / zone / line settings of indoor units
• The settings of indoor units can be configured collectively by groups, zones or lines.
• Groups 1-64 correspond to the central control addresses 1-64 for indoor units, respectively. See “6.Central
control address (group number) setting”.
• A Smart Manager has two TCC-LINK communication lines: line 1 and line 2. Each line can contain up to 64
groups and 64 zones, and 128 groups and 128 zones can be set in total.
• A zone is a control unit consisting of a combination of any indoor units. You can make up to 64 zones pairing any
of up to 64 groups. For setting zones, see “8.Zone setting”.
Connecting interface
Connect the Energy monitoring relay interface and Digital Input / Output relay interface to the RS-485
communication cable. See the Installation Manuals of the interface for details.

Installation Manual
6 Central control address (group number)
setting
• Central control addresses must be assigned to all air conditioners to be controlled.
• Under the control of the Smart Manager / Central Remote Control, central control address equals group number.
<Preparations for central control address (group number) setting>
• Turn on the power of all indoor and outdoor units.
• This Smart Manager / Central Remote Control or a standard wired remote controller is necessary for setting
central control addresses.
• Terminate the operation of air conditioners, and then set central control addresses.
* To set central control addresses with the Smart Manager / Central Remote Control, initial communication with
all connected indoor and outdoor units must have been completed. Therefore, wait at least 10 minutes after
power-on, and then start central control address setting.
NOTE
If the address setting is made before the initial communication is completed, an address is not assigned
to some units.
• Connect terminals U1 and U2 in the outdoor unit (Header unit) to the relay connector of terminals U3 and U4.
• Set SW30-2 on the interface P.C. board of the outdoor unit (Header unit) to ON only for one system, and to OFF
for others.
* The location of SW30 is shown in the wiring diagram supplied with the outdoor unit.
<Setting central control addresses (group numbers)>
Use “manual setting from wired remote controller,” “manual setting,” or “automatic setting” to set central control
addresses.
A Manual setting from wired remote controller
Set central control addresses (group numbers) from a standard wired remote controller.
* The following setting procedure is described based on button operations of the wired remote controller RBC-
AMT32UL.
(1) Press the button and button simultaneously for at least 4 seconds.
(Note: Do not press the button during setting.)
(2) Press the button to change the CODE No. 03.
(3) Set central control addresses (group numbers) with the buttons.
• Group numbers used for the Smart Manager / Central Remote Control are central control addresses (DN item
03).
• The effective address range is 1 to 64. However, there must be no duplicate address on the same line.
• An address value of 99 indicates that the address is not set.
(4) Press the button to fix the setting.
(5) Press the button to exit the address setting mode.
* This setting procedure may vary depending on the wired remote controller model.
* Perform these steps while air conditioners are not working.
