Controller Options
Single Zone High Efficiency Standard Wall Mount systems include a wireless handheld remote controller
(Model No. AKB74955602), but 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.
• 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 High Efficiency Standard Wall Mount Engineering Manual, or con-
tact an LG representative for more 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). Com-
munication 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.

Dry Contact
A Dry Contact can also be connected to the High Efficiency 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, Single Zone High Efficiency systems can be connected
to a central controller if a PI-485 VNet Accessory is installed in the
outdoor unit. See the Central Controller manual for wiring specifica-
tions.
