It is available to operate the air-conditioning unit and to monitor the operation status with the external control unit (remote display)
by sending the input/output signal through CNT connector on the indoor control PCB.
①
Connect a external remote control unit (procured locally)
to CNT terminal.
②
In case of the pulse input, switch OFF the DIP switch
SW2-1 on the interface PCB.
③
When setting operation permission/prohibition mode,
switch OFF the DIP switch SW2-3 on the interface PCB.
Connection of Superlink E board
Functions of CNT connector
①
Switch ON the DIP switch SW2-2 (Factory setting: ON) on the interface PCB.
②
Wiring connection between the interface and the Superlink E board.
③
Clamp the connection cables with cable clamps.
Regarding the connection of Superlink E board, refer to the instruction manual of Superlink E board.
For electrical work, power source for all of units in the Superlink system
must be turned OFF.
Caution:Wireless remote control attached to the indoor unit can be used in parallel, after
connecting the wired remote control. However, some of functions other than
the basic functions such as RUN/STOP, Temperature Setting, etc. may not work
properly and may have a mismatch between the display and the actual behavior.
