Controller Options

Handheld Remote Controller
Single Zone Art Cool Premier Wall Mounted systems include a wireless handheld remote controller (Part No.
AKB74955602). Optional LG-suppled wired controllers are available. See "Functions, Controls, Options"in the
Engineering Manual, or contact an LG representative for more information.
Wireless Handheld Remote Controller features:
• Display Panel: Displays operation conditions.
• On / Off Button: Turns system operation on and off.
• Mode Button: Selects the operation mode: Cooling,
Heating, Auto, Dry (Dehumidification), or Fan.
Wired Controller Connections
Optional controllers (see the Single Zone Art Cool Premier Wall-Mounted Engineering Manual, or contact an
LG representative for more information) connect to the Single Zone Art Cool Premier Piping Wall-Mounted
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.
to black (ground wire) terminals from the remote controller to the indoor unit terminal blocks.
Dry Contact
A Dry Contact can also be connected to the Art Cool Premier indoor
unit using the CN-CC connection on the indoor unit PCB. The Dry
Contact DC is shipped with a specific connector that is used to con-
nect to the indoor unit.
Central Controller
Additionally, Single Zone Art Cool Premier systems can be con-
nected to a central controller if a PI-485 VNet Accessory is installed
in the outdoor unit. See the Central Controller manual for wiring
specifications.
