8-2-1. 1:1 Model Connection Interface (TCC-LINK adapter)
1. Function
This model is an optional P.C. board to connect the indoor unit to 1:1 model connection interface.
2. Microprocessor block diagram
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 con-
nected 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)
∗∗∗∗∗
In case of DI, SDI series, the address is necessary to be set up again from the wired remote
controller after automatic addressing.
