Controller Options
Wall-mounted indoor units include a wireless handheld remote controller (Model No. AKB74955602), but optional LG-supplied wired control-
lers are available. After all wiring is connected to the indoor and outdoor units, test the accompanying remote controllers for performance. As
always, follow all safety warnings and notes when operating the units using the remote controller. Additionally, all of the Multi F / Multi F MAX
outdoor units can use the following controllers when accompanied with the PI 485 VNet Accessory:
• AC Smart
• ACP
Communication Cables From Indoor Units to Remote Controllers
• 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.
• If using the LG Controller / Extension cable and the length needs to be further extended, the LG Extension Kit (sold separately) must be
used. A maximum of four (4) kits (up to 165 feet) can be used.
• Remote controllers have hardwired connections: SIG - 12V - GND (Comm.) terminals.
• Indoor unit controller connections depend on type of indoor unit being installed. Some indoor units use terminal block connections; other
indoor units use Molex connections. See diagrams below for the two options. Refer to the wiring diagram schematic found in the indoor unit
itself, or to the indoor unit wiring diagrams in the Engineering Manuals for more information.
• NEVER splice, cut, or extend cable length with field provided cable. Always include enough cable to cover distance between the indoor
unit and the remote controller.
• Set the indoor unit operating parameters using DIP switches, or by setting up the remote controller. Refer to the indoor unit installation
manuals for more details.
