Controller Options
Handheld Remote Controller
Single Zone Extended Piping 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.
• 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.
Dry Contact
A Dry Contact can also be connected to the Extended Piping 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 Extended Pipe 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.

Wired Controller Connections
Optional controllers (see the Single Zone Extended Piping Wall-Mounted Engineering Manual, or contact an
LG representative for more information) connect to the Single Zone Extended 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.
