Controllers - LG LS120HSV4 Installation Manual

General Communication Cable Specifications
• Use a four (4) conductor, shielded, stranded cable between the Single Zone outdoor unit and the indoor unit.
• Minimum 18 gauge shielded CVVS or CPEVS cable.
• Insulation material as required by local code.
• Rated for continuous exposure of temperatures up to 140°F.
• Maximum allowable cable length: 984 feet.
• Firmly attach the cable; provide slack but secure in a way to prevent external forces from being imparted on the terminal block.
• Wiring should be completed without splices.
• Terminate the cable shield to a grounded surface at the outdoor unit only.
• Always verify the communication cable is connected to a communications terminal on the Single Zone unit. Never apply line voltage
power to the communication cable connection. If contact is made, the PCBs may be damaged.
• The shield of the communications cable connecting the outdoor unit to the indoor unit should be grounded only to the outdoor unit frame.
• Tie the shield of each cable segment together using a wire nut at each indoor unit. Maintain polarity throughout the communication network.
• Position the outdoor unit communications cables away from the power wiring. Refer to minimum spacing requirements provided in
Table 18.
• Never use a common multiple-core communications cable. Each communications bus shall be provided a separate cable (i.e., between
outdoor unit and indoor unit).
Communication Cables Between the Single Zone Unit and the Controller
• Simple Controllers: field-provided, 18 gauge, stranded four-conductor communication cable (shielded).
• All other Central Controllers: field-provided, 18 gauge, stranded two-conductor communication cable (shielded).
• Insulation material as recommended by local code.
• Connect all central control devices such as ACP, BACnet
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.
Controller Options
Refer to Table 19 as to which remote controller models is used for each system. Once all wiring is connected to the indoor and outdoor units
be sure to test the accompanying remote controllers for performance. As always, follow all safety warnings and notes when operating the
Single Zone units using the remote controller. Additionally, most of the Single Zone High Efficiency outdoor models can use the following
controllers when accompanied with the PI 485 VNet Accessory:
• AC Smart
• ACP
• BACnet®
