Warning
• Service should be performed by a qualified electrician
Attempting to carry out service work on your own, and doing so incorrectly, may result in electric
shock or fire.
• Electrical work must be performed by a qualified electrician in accordance with
this Service Manual. The work must satisfy all local, national and international
regulations
Inappropriate work may result in electric shock or fire.
• Be sure to turn off the power before starting work
Failure to do so may result in electric shock.
• Use only the power adapter supplied with this unit
A power adapter other than that supplied with this unit may provide a different voltage and have
different polarity (+) (−), which could lead to fire, explosion or generation of heat.
• Do not modify the unit
Doing so may result in excessive heat or fire.
The following instructions
must be observed.

1Product Overview
BN interface relays communications between Building Management Systems and VRF Systems in order to observe and control
the VRF Systems from Building Management Systems. The communication protocol used between Building Management
Systems and the BN interface is BACnet, an open network communication protocol for building automation.
BACnet Protocol Revision is ANSI/ASHRAE Standard 135-2012 (Revision15).
This product is for use when connected to TU2C-LINK Uh Line (hereinafter referred to as Uh Line).

NOTE
*1 The setting of each property changes with the model. *2 This object can be used by the TU2C-LINK model.
In order to issue a notice code, the notice code must be registered on the air conditioner side. For details of notice code, refer to the air conditioner service manual.
*3 In the case of Auto cool temperature setting ≥Auto heat temperature setting, both setting values will be transmitted to the indoor unit.
In the case of Auto cool temperature setting < Auto heat temperature setting, the setting values will not be transmitted.
To change the value of "Auto cool temperature setting" or "Auto heat temperature setting", perform the change while operation mode is "Auto". Precautions when changing the value of "Auto cool temperature setting" or "Auto heat temperature setting" on the same indoor unit.
• Before performing the change, wait at least 10 seconds after the last change. • Do not change both the "Auto cool temperature setting" and "Auto heat temperature setting" values in one "WritePropertyMultiple" service operation.
