Controller Options
Single Zone Art Cool Mirror Wall Mount systems include a wireless handheld remote controller (Model
No. AKB74955602), but optional LG-suppled wired controllers are available. See “Functions, Controls,
Options”, 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.
• Temp Up / Down Buttons: Adjusts the desired room temperature in the different modes.
• Fan Speed Button: Sets desired fan speed.
• Reset: Initializes the handheld remote control settings.
Wired Controller Connections
Optional controllers (see the Single Zone Art Cool Mirror Wall Mount Engineering Manual 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.

When using field-supplied controller cable, make
sure to connect the yellow to yellow (communica-
tions wire), red to red (12V power wire), and black
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 Mirror Wall
Mount 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 connect to the indoor unit.
Central Controller
Additionally, Art Cool Mirror Wall Mount systems can be connected
to a central controller if a PI-485 VNet Accessory is installed in the
outdoor unit. See the applicable Controller manual for wiring speci-
fications.
