6Setting
The following settings are necessary to use the LN interface.
TCC-LINK
REQUIREMENT
The set data is read only when the power is turned on.
When changing the SW1/SW2 setting, push the reset switch SW6 after setting.
Indoor unit central control address and SW1/SW2 setting
• SW1/SW2 Set the number of indoor units to be connected.
Set the maximum of the indoor unit central control address according to the table below.
The factory setting is “3F” (64 units connected).
(*) Set the indoor unit central control address from 1 to 64 consecutively.
This means that the maximum of the central control address equals the number of connected
indoor units.
However, if an address is omitted, the maximum of the central control address differs from the
number of connected indoor units. In this case, set the maximum of the central control address
according to the table below.
Note:
The system works normally when the set value is larger than the maximum.
However, it will result in communication loss.

7Trial Operation
REQUIREMENT
• Be sure to specify each unique central control address of the indoor unit.
• Be sure to push the reset switch, SW6 on the LN interface after changing or adding the central control address
of the indoor unit.
Check the communication status between LN interface and indoor units. It can be checked even when the
LONWORKS®system is not running.
By using SW1, SW2, and SW3, check the communication status of each connected indoor unit with LED4 and
LED5.
Checking TCC-LINK communication status
Set bit 2 of SW3 to “ON” during normal operation.
Set the central control address of the target indoor unit with SW1 and SW2 according to “Indoor unit central control
address and SW1/SW2 setting”
Example:
When checking communication status of indoor unit of central control address 25:
Set bit 2 of SW3 to “ON”, SW1 to “1”, and SW2 to “8”.
Indication of TCC-LINK communication status
LED4 and LED 5 show communication status of the indoor unit selected by SW1 and SW2.
End of TCC-LINK communication status check
Re-set SW1 and SW2 to the number of connected indoor units, and set bit2 of SW3 to “OFF”.
REQUIREMENT
Be sure to re-set SW1 and SW2 correctly.
Wrong setting may result in a malfunction when the unit is reset.

Normal ON OFF
Normal ON ON Communication with the indoor unit was established previously, but is
disabled currently.
No indoor unit OFF ON Communication with the indoor unit has never been established.
Invalid indoor unit OFF OFF More indoor units are connected than the LN interface can control.
