Procedure to setup address 65 to 128 from the remote controller
Under TCC-Link settings (factory shipping settings), setting addresses from 65 and above are not available
from the remote controller. Setting the indoor address or the zone address to 65 to 128 must be done under
TU2C-Link settings, which can be performed by the procedures shown below.
* Be sure that all of the outdoor units, indoor units, and the remote controller in the same system support
TU2C-Link.
TU2C-Link communication is not available if any of these do not support TU2C-Link.
Method 1 (Changing the address after automatic address setup)
Follow the procedures below if the power supply and communication line wiring work has been completed.
1) Turn the power for every outdoor unit and indoor unit on.
2) Perform "Automatic address setup" from the header outdoor unit.
The system address, indoor address, and the group address will be set for every indoor unit in the
system automatically.
3) Perform "Communication setting" from the header outdoor unit.
TU2C-Link will be set if all the outdoor units, indoor units, and the remote controller support TU2C-Link.
(Outdoor DN code (O.DN) [082]=0003, indoor DN code (I.DN) [FC]=0003)
For the units in the farthest rooms, the indoor termination resistance will automatically be set to on.
(Indoor DN code (I.DN) [1FC]=0001 (ON))
4) Change the indoor address (or the group address) to any address within 1 to 128 according to the
method to change the indoor address using the remote controller.
* If there are more than 65 indoor units connected:
Addresses above 65 will automatically be set by automatic address setup even if TCC-Link settings are
implemented.
While the TCC-Link settings are set, indoor units which are assigned with the addresses 65 to 128 will
not work, until setting the TU2C-Link settings by performing communication settings after the automatic
address setup, which will render the indoor units 65 through 128 available.
* The check code [E16] or [L08] will show up if operation is attempted while the TCC-Link setting is
implemented and the indoor units with the indoor address 65 to 128 are connected.
