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