When using eld-supplied controller cable, make sure to connect
the yellow to yellow (communications wire), red to red (12V power
wire), and black to black (ground wire) terminals from the remote
controller to the indoor unit terminal blocks.
Wired Controller Connections
Controllers can connect to the indoor unit in one of two different
ways.
1. LG Wired Remote Extension Cable with Molex plug (PZC-
WRC1; sold separately) that connects to the CN-REMO
terminal on the indoor unit PCB.
2. Field-supplied controller cable that connects to the indoor unit
terminal block (must be at least UL2547 or UL1007, 22 AWG,
two-core, one-shield core, at least FT-6 rated if local electric
and building codes require plenum cable usage).
Due to our policy of continuous product innovation, some specications may change without notication.
