Termination resistance setting
• TU2C-LINK / TCC-LINK termination resistance setting ............<For TCC-LINK>
Leave just 1 line of the termination resistance in the
interface board of the outdoor unit (centre unit) ON, and
turn all the others OFF. (Refer to the wiring diagram
attached to the outdoor unit for the position of SW.)
<For TU2C-LINK>
For the central control wiring (Uh line), set the termination
resistance that is farthest away on the wiring between this
central controller and the other unit (VRF, light
commercial, air to air heat exchanger, general purpose
control interface, air to water heat pump) to ON.
Refer to the manual of each model for the termination resistance setting method.
Shield grounding process
• Central control wiring shielded wire ...........................................When using the central remote controller with one unit,
open the shielded wire of the central control wiring and
perform insulation processing.
When using the central remote controller with multiple
units, connect the shield of the central control wiring to the
closed end and open the shield at the final end of the
central remote controller to perform insulation processing.
Perform the central control wiring shield grounding on the
air conditioner side.
REQUIREMENT
• Be sure to install a circuit breaker or all-pole isolating switch (with a contact breaking distance of at least 3 mm) on the
primary side of the power supply.
• Fasten the screws to the terminal block with torque of 0.5 N•m.

5-2. Setting up equipment data in the indoor unit
Obtain the equipment data of the indoor unit that is controlled by the BN interface from the indoor unit via the Uh Line
communication cable.
Preparing to set up equipment data in the indoor unit
• Central Control address must be set in the indoor unit you want to control.
For information on how to set the address, refer to the installation manual of each indoor unit.
• Turn on all indoor and outdoor units. Set up as follows, waiting 10 minutes after turning on all the units.
Setup work
• Turn on the BN interface.
• When 10 minutes has elapsed since turning on the BN interface, hold down the shutdown button for 4 seconds or longer.
L1 LED goes on.
• When the BN interface has started up normally, start reading the equipment data of the interface unit. During this operation
L1 LED will be on while L2 LED will be blinking on the BN interface.
• When reading of equipment data in the indoor unit ends normally, the BN interface will automatically start preparing for
BACnet communication. L1 LED on the BN interface is blinking.
• When the preparations for BACnet communications end normally, L1 LED and L2 LED of the BN interface will start
blinking.
• If an error occurs during reading of equipment data from the indoor unit or when preparing for BACnet communications,
L1 LED and L2 LED of the BN interface will go on.
Determining the cause of such an error will require the use of engineering tools. For details, contact your dealer.
5-3. Cause of problem occurring during setup
6Turning off the BN interface
Press the shutdown button, then wait 5 minutes before turning it off.
CAUTION
As the air-conditioning search mode will be engaged if the shutdown button is pressed for 4 seconds or longer, do not hold down
the button.
Cause of problem Cause Action
The indoor unit cannot be found.
The indoor and outdoor units have not been
turned on.
Make sure that indoor and outdoor units are
turned on.
The indoor and outdoor units are being
initialized and it is not possible to
communicate with them.
LINK(Uh) LED does not blink at all
Make sure that indoor and outdoor units are
turned on.
Make sure they have been on for at least
10 minutes.
The Uh Line cables have been incorrectly
connected. Connect the cables correctly.
The central control address has not been set
in the indoor units.
Make sure that the central control address has
been set in the indoor units.
The central control address set in
the indoor units are not unique.
The same central control address has been
set in a number of indoor units.
Make sure that the central control address has
been correctly set in the indoor units.
