Wired Controller Connections
Optional controllers (see “Functions, Controls, Options”, or contact an LG representative for more
information) can connect to the Single Zone Art Cool Mirror 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.
