If any indoor units were specified to operate in unison:
• Before running cable, decide which indoor unit will be the
“Main.” The other indoor units in that group will be designated as
“Sub(s).” The zone controller will be connected to the “Main.”
• Set the pertinent DIP switch at each indoor unit to identify the
Main and Sub(s).
• Use a daisy chain conguration and connect all of the group’s
indoor units together starting at the “Main” unit.
• NEVER splice, cut, or extend LG provided cable with eld
provided cable. Always include enough cable to cover distance
between all components.
• Perform group control settings and connect the group control
wiring after the system auto address and auto pipe procedures
have been completed.
For indoor units with hardwired connections SIG - 12V - GND
(Comm.) terminals:
• From the controller to the main indoor unit, use 22 AWG,
3-conductor, twisted, stranded, unshielded. All wiring must com-
ply with all applicable local and national codes.
• From the main indoor unit to the sub indoor unit(s), daisy chain
using 22 AWG, 3-conductor, twisted, stranded, unshielded
( Do not attach wire to 12VDC terminal to the sub indoor
units). All wiring must comply with all applicable local and
national codes.
For indoor units with CN-REMO connections:
Use Group Control Kit (sold separately) containing extension and
Y-splitter cables. Use one (1) group control cable kit for each indoor
unit in the group except for the last indoor unit.
• Cable connected to zone controller is the factory default connection.
• Indoor unit connections depend on indoor unit type.
