PRODUCT CATALOG System Controls
Controls Multi V Controls By utilizing advanced control strategies, LG’s HVAC and variable refrigerant flow (VRF) systems not only save energy, but they also increase operational convenience and living standards. LG offers a variety of control systems, including individual zone control, central control, and building management system integration control options that scale easily to meet the requirements of jobs small to large.
Controls Ease of Implementation The LG communications network is based on simple two-wire, daisy chain architecture that reduces installation cost and complexity. This allows the system to be installed by the mechanical contractor eliminating the need for costly building management system integration contractors and specialists. LG V-Net controls are designed and engineered for use with LG air conditioning products and this eliminates compatibility and interoperability issues.

Controls 7-Day Programmable Controller [Wired Remote Controller] (PQRCVSL0(QW)) PQRCVSL0QW PQRCVSL0 (White) (Black) The 7-Day Programmable Controller allows control of indoor unit operation mode, fan speed and temperature setpoint. Programmable schedule allows for automatic energizing and shutdown of the indoor unit up to twice a day with setpoint control.
Controls Handheld Controller [Wireless Remote Controller] (PQWRHDF0) The Handheld Controller allows wireless control of indoor unit operation mode, fan speed and temperature setpoint. The controller works with any indoor unit with a unit-mounted infrared eye or connected to a wired controller with an infrared receiver.
Controls Central Controllers AC Ez (PQCSZ250S0) The AC Ez controller provides a centralized point where up to 32 indoor units or indoor unit groups can be controlled and monitored. The controller allows control of the operating mode, fan speed, louver direction and temperature setpoints of all indoor units (individually, by group or all). Eight individual programmable schedules allow for automatic energizing and shutdown of indoor units (individually or by group) with operation mode and setpoint control.
Controls AC Smart II (PQCSW320A1E) As LG’s most advanced central controller, the AC Smart II delivers unparalleled options for Multi V system management and administration from a central location. The AC Smart II provides a flexible platform from which a number of energy saving control sequences can be managed including system scheduling and supervision over local zone controllers in occupied spaces.

Controls Integration Solutions Open systems architecture ensures product diversity and interoperability among the many vendors furnishing HVAC control systems to the marketplace. LG supports the open protocol environment with unique gateway solutions that provide seamless end-to-end integration of third-party BACnet® and LonWorks® based building management systems with the full portfolio of Multi V air conditioning products.
Controls BACnet ® Gateway (PQNFB17B0) The BACnet® Gateway allows integration over BACnet®/IP and is BTL certified (ASHRAE 135-2004). The gateway provides open-protocol, 2-Way communication between LG’s Multi V air conditioning products and various brands of building automation systems to control and monitor up to 256 indoor units.
Controls Controls Accessories Remote Temperature Sensor (PQRSTA0) The Remote Sensor allows for remote temperature measurement. In some applications (such as high ceilings) the unit-mounted return air thermistor may not accurately represent the space temperature. The thermistor sensor is provided with 50 feet of wiring and plug for quick connection to the indoor unit control board. The remote sensor is for use with ducted and ceiling cassette indoor units.
Controls Wired Remote Extension Cable (PZCWRC1) The Group Control Extension Cable is used to increase the distance between a remote controller and an indoor unit or between indoor units in a control group. This extension provides an additional 32 feet of cable. Cable may be field supplied for 24-48 MBh 4-Way Ceiling Cassettes (TM, TN, TP frames).
Controls Auxiliary Heater Relay Kit (PRARH0, PRARS0) The Auxiliary Heater Relay Kit adds coordinated control of an external heater to normal heat pump heating operation by one set of dry contacts. The output will energize at 2.7 ºF below setpoint and de-energize at 2.7 ºF above setpoint. • PRARH0 applies to high static duct, low static duct, ceiling suspended and 1-Way, 2-Way and 4-Way ceiling cassette units.
Controls Dry Contact Unit for Setback (PQDSBC) The Dry Contact Unit for Setback enables the indoor unit to be controlled and monitored by third-party controls by way of contact closure of 2 binary inputs and 2 binary outputs. The binary inputs are used in sequence to turn the indoor unit On/Off, force thermo-off, set remote controller lock, set mode*, set fan speed, and set occupied and unoccupied setpoints for setback depending on what setting has been pre-configured during commissioning.
Controls Power Distribution Indicator (PDI) (PQNUD1S01) PDI is a hybrid energy monitoring technology that combines direct energy measurement with software calculated and apportioned electrical performance data. Each system, represented by a single, dual or triple arrangement of outdoor units is monitored by an LG specified (and field furnished) AC watt-hour transducer that provides a pulse output relative to power consumption.
