3. 1:1 model connection interface wiring connection
CAUTION
1) When controlling DI, SDI series collectively, 1:1 model connection interface (This option) is required.
2) In case of group operation, twin-triple operation, the 1:1 model connection interface is necessary to be
connected to the header unit.
3) Connect the central control devices to the central control system wiring.
4) When controlling DI, SDI series only, turn on only Bit 1 of SW01 of the least line of the system address No.
(OFF when shipped from the factory)
5) In the following cases, change the communication type to TCC-Link with the wired remote controller.
Refer to 28 Communication type setting of 5-2. Control Specifications.
• When performing group control in combination with the indoor unit dedicated to TCC-Link (other than RAV-

series).
• When connecting to the central control device dedicated to TCC-Link.
∗∗∗∗∗
In case of DI, SDI series, the address is necessary to be set up again from the wired remote
controller after automatic addressing.
