Group control through a remote controller
Group control of multiple indoor units (8 units) through a single remote controller
Connection of power wires and communication wires
Remove knockouts on the piping / wiring panel on the front of the unit or the panel on the bottom to get the power and
communication wires through the holes.
Use protective parts (such as jugged bushings) to prevent the power wires and communication wires from directly
touching the edge of the sheet metal.
The local installer must purchase the non-removable jugged bushings to wrap around the hole, and use insulated
bushings (locally purchased) to protect the wires from directly touching the sheet metal.
NOTE
Separate the power wire and communication wires.
