Test run
To perform test run of the BN interface, BACnet communication settings and the equipment data of the connected indoor units
are required.
5-1. BACnet communication settings
Set the IP address of the BN interface and the device object instance number of the BACnet communications. These setting
can set from Setting File Creation Software. For details, contact your dealer.
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 TCC-LINK
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.
