information) can connect to the Single Zone High Efficiency Standard Wall Mount indoor unit in one of
two different ways.
1. LG Wired Remote Extension Cable with Molex plug (PZCWRC1; 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, and at least FT-6 rated if local electric and building codes require plenum cable
usage). Communication cable from indoor unit to remote controller(s) is to be 22 AWG, 3-conductor,
twisted, stranded, unshielded. Wiring must comply with all applicable local and national codes.
