[. . . ] · Turn off the main power supply switch or breaker before attempting any electrical work. Failure to do so may cause electric shock. · Perform installation work properly according to this Installation Manual. Improper installation may result in electric shock or fire. [. . . ] Any modification may cause a malfunction, resulting in overheating or fire. CAUTION · Perform wiring correctly in accordance with the specified the current capacity. Failure to do so may result in short-circuit, overheating, or fire. · Connect the specified cables for the terminals securely to prevent external forces from affecting them. Failure to do so may result in disconnection, overheating, or fire. 2 (EN) TCS-NET Relay Interface Installation Manual 2 Introduction Applications/Functions/Specifications Applications · The TCS-NET Relay Interface is used to connect air conditioners (with TCC-LINK installed) to the air conditioner control system or BACnet system. Functions · The TCS-NET Relay Interface converts signals between TCC-LINK and RS-485.

Use the attached screws. No good REQUIREMENT Do not install the unit in any of the following places. · Humid or wet place · Dusty place · Place exposed to direct sunlight · Place where there is a TV set or radio within one meter · Place exposed to rain (outdoors, under eaves, etc. ) Installation Space and Maintenance Space A side space for connecting through cable inlets and an upper space for maintenance must be reserved before installation. Turn bit 1, 2 and 3 of SW5 ON. Set the TCS-NET Relay Interface address with SW1. Assign 1 to 8 to each address to avoid duplication. CAUTION: The SW1 setting is read when the power is turned on. Push the reset switch SW7 after changing the address. 7 (EN) Remote controller CAUTION: RS-485 signals A and B have polarity. Be careful when connecting the RS-485 wires. Central remote controller The shield of RS-485 cable should be open and insulated. It is not connected to the terminal block. 1 Indoor unit Outdoor unit Remote controller Crimp 3 wires with a closed end wire joint.

SW6 SW1 8 Indoor unit Indoor unit NL TCS-NET Relay Interface Installation Manual 6 Setting The following settings are necessary to use TCS-NET Relay Interface. · SW1 TCS-NET Relay Interface address set switch When two or more TCS-NET Relay Interface are used, set a different address for SW1 to avoid address duplication. Assign addresses in an ascending order. CAUTION · Set relay interface addresses according to the air conditioner address table. For the relay interface whose address SW1=1, perform terminator resistor setting. · When the SW1 setting has been changed, push the reset switch SW7. [. . . ] · When the SW1 setting has been changed, push the reset switch SW7. The new address setting is read. · SW2 · SW3 · SW4 · SW5 · SW6 Test switch Test switch Test switch · SW7 Not used during operation. Set these switches to zero (0) or "all OFF". RS-485 terminator resistor select switch Set "Resistor set (120 ohm)" only when the relay interface address SW=1, and set "open" for other relay interfaces. SW1 SW4 TCC-LINK terminator resistor select switch The TCC-LINK terminator resistor is set on the air conditioner side. [. . . ]
