6Setting
The following settings are necessary to use Modbus Interface.
• SW1 Modbus Interface address set switch
When two or more Modbus Interface are used, set a different address for SW1 to avoid address
duplication. Assign addresses in an ascending order.
CAUTION
• For the Modbus Interface whose address SW1=1, perform terminator resistor setting.
• When the SW1 setting has been changed, press the reset switch SW7. The new address setting is read.
• To clear all accumulated operating values to 0, set SW2 to 3 and press the reset switch SW7, and then set SW2
to 0 and press the reset switch SW7 again.
• To set the delayed response mode, set SW2 to 4 and press the reset switch SW7. With this mode, a slave delays
responding to the requests from the master for 250ms.
Leave SW2 set to 4 to keep the response mode set as delayed response mode.
• When the setting of bit3 and bit4 of SW3 has been changed, press the reset switch SW7. The new set value is read.
• SW2 Test switch Not used during operation. Set these switches to zero (0) or “all OFF”.
• SW3 Test switch Bit1: Switches the Modbus Interface software.
Bit2: Switches the LED5 display for test runs.
Bit3, 4: RS-485 baud rate setting (9600/19200/38400) bps.
• SW4 Test switch Not used during operation.
• SW5 RS-485 terminator resistor select switch
Set “120 ohm” only when the Modbus interface address SW=1, and set “open” for other Modbus
interfaces.
• SW6 TCC-LINK terminator resistor select switch
The TCC-LINK terminator resistor is set on the air conditioner side. Set SW6 to “open”.
• SW7 Reset switch
When performing an address setting with SW1, push this reset switch after the address setting to read
the set value.

7Test run check
Before starting test run
• Set the indoor unit central control address so that it does not match any other indoor unit addresses.
• Be sure to press the reset switch SW7 on the Modbus Interface when the indoor unit central control address
setting has been changed or added.
Test run
(1) Check the communication status between Modbus Interface and indoor unit or TCB-IFCG1TLE with LED5.
Check that the communication between Modbus Interface and each indoor unit or TCB-IFCG1TLE connected
is normally performed by selecting an indoor unit or TCB-IFCG1TLE using SW1 to SW3.
Confirming procedure:
• Set bit2 of SW3 to “ON” during normal operation.
• Set the central control address of the target indoor unit with SW1 and SW2. Set SW1 and SW2 according to
the “Indoor unit central control address and SW1/SW2 setting” table below.
• Communication status is displayed by LED5.
