• Only use LG provided three-core communications cable between the indoor unit and the wall-mounted
zone controller.
•
NEVER splice, cut, or extend cable length with field provided cable. If the length needs to be
extended, the LG Extension Kit (sold separately) must be used. A maximum of four (4) kits (up to 165
feet) can be used.
• Set the indoor unit operating parameters using DIP switches or by setting up the zone controller. Refer
to the indoor unit installation manuals for more details.
Cable connected to Zone Controller is the factory default connection.
• AC EZ Simple Central Controllers: Field-Provided, 18 Gauge, Stranded Four-Core Communication Cable (shielded).
• All Other Central Controllers: Field-Provided 18 Gauge, Stranded Two-Core Communications Cable (Shielded).
• Insulation material as recommended by local code.
• Separate communications cables and power wiring. See Table 30 for appropriate distances.
Connect all central control devices such as AC products, ACPs, BACnet and LonWorks gateways, and energy recovery ventilators all on the
same cable. Order does not matter. Polarity does. Keep “A” terminals with “A” terminals, and “B” terminals with “B” terminals. Starting at the
outdoor unit, terminate the cable on terminals Internet A and Internet B. Route the cable as needed between each device.
