INTRODUCTION

System Conguration

Using LGMV

Mobile LGMV consists of a hardware wifi module, an interface cable, and a free application (app) for Android devices. The user must supply the Android smartphone or tablet. Before using Mobile LGMV, you must download and install the latest version of the free app from the LG website listed in this manual.

The wifi module and the smartphone app together provide monitoring and troubleshooting capability for LG air conditioning systems. Mobile LGMV functions only with LG products.

Mobile LGMV can display and graph operational data for the air conditioner system including the indoor units and the outdoor unit. Mobile LGMV also displays error codes and a troubleshooting guide (if previously downloaded). Indoor unit operating mode can be set through Mobile LGMV.

To use Mobile LGMV you must be a trained HVAC service technician familiar with variable refrigerant flow (VRF) systems in general and with LG’s products. You should understand the inverter air conditioning operation cycle, the meaning of the data displayed by Mobile LGMV, and how to use the data to troubleshoot the system.

Figure 3 shows the LGMV app and wifi module in a typical troubleshooting application. The Mobile LGMV wifi module connects to an LG outdoor unit via the supplied cable. Table 1 lists Mobile LGMV smart phone/tablet requirements.

Note:

• Some functions may not operate or the screen display may be degraded depending on the smartphone used

• Mobile LGMV will not function normally if the operating environment does not meet the minimum specifications

INTRODUCTION

Figure 3: Typical Mobile LGMV Troubleshooting Conguration

Mobile LGMV Operating Considerations

• Mobile LGMV processes data in real time. If other functions of the smartphone are

used at the same time as Mobile LGMV, smartphone resources may be insufcient

for Mobile LGMV to process data or the Mobile LGMV connection may be disconnected. Please use the product with this in mind. Always use a smartphone with at

least the minimum recommended specications.

• The Mobile LGMV application may unexpectedly end due to insufcient system resources.

• Transmission/reception data volume may increase according to the number of indoor and outdoor units. Mobile LGMV response speed may be slower for some smart-

phone specications.

• Wireless transmission/reception distance may be reduced or communication may be disconnected due to the operational environment (weather, electromagnetic interference or physical obstacles).

• Mobile LGMV may not work correctly with routed smartphones.

• As communication distance between the Mobile LGMV wifi module and the smart-

phone increases, smartphone wi output may increase, causing greater drain on the

smartphone battery. During use, keep the smartphone as close as safely possible to the Mobile LGMV wifi module.

• Disconnect the Mobile LGMV wi module from the ODU when troubleshooting is complete.

Hardware Installation

Hardware Description

Mobile LGMV hardware consists of a wifi module and a two-piece cable (Figure 15).

The wifi module sends and receives wifi signals to/from the smartphone. The cable connects the wifi module to the outdoor unit. The cable has two sections because there are two types of outdoor unit connectors, one for Multi V products and one for Multi F products. When testing Multi V products, leave the Multi V extension connected. When testing Multi F products, temporarily remove the Multi V extension.

Input power to the outdoor unit remains connected and on during this procedure. Do not touch any exposed outdoor unit wiring, terminals, or other electrical components with tools or exposed skin. Only trained technicians should install, use, or remove this equipment.

Improper installation or use may result in re, explosion, electric shock, physical injury and/or death.
