6. MULTIPLE REMOTE CONTROL DISPLAY
You can control several units with a multiple remote control display, by
wiring an optional multiple display adapter (PAC-SA88HA-E) with relays
and lamps on the market.
How to wire
(1) Connect the multiple display adapter to the connector CN51 on the
indoor controller board.
(2) Wire three of the five wires from the multiple display adapter as shown
in the figure below.

7. AUTO RESTART FUNCTION
By setting the dip switch SW1-8 to ON, the air conditioner can be started/stopped by power supply ON/OFF.
If the air conditioner is OFF before the power failure, it will not start operation by power restore.
•This function is mainly to emergency performance when the power supply stops temporarily. Therefore, since the protec-
tion function (for example, clank case heater and prevention from restarting in 3 minutes, etc.) of the device is not operat-
ed, this function should not be used mostly.
