For continual product development, LG Electronics U.S.A., Inc.,
reserves the right to change specications without notice.
LG Smart Inverter Monitoring System (SIMs) 2.0 is for use
with LG duct-free split (DFS) systems only. Do not attempt
to use SIMs 2.0 with any other type of system.
The information in this manual is intended for use by an
with the U.S. National Electric Code (NEC) who is equipped
with the proper tools and test instruments.
Failure to carefully read and follow all instructions in this manual may
result in equipment malfunction, property damage, personal injury
and/or death.
Input power to the outdoor unit remains connected and
on during procedures in this manual. Do not touch any
exposed outdoor unit wiring, terminals, or other electrical components with tools or exposed skin. Only qualied
technicians should install, remove, or re-install this unit.
Improper installation or use may result in re, explosion, electric
shock, physical injury and/or death.
All electrical work must be performed by a licensed electrician and conform to local building codes or, in the absence
of local codes, with the National Electrical Code, and the
instructions given in this manual.
If the power source capacity is inadequate or the electric work is not
performed properly, it may result in re, electric shock, physical injury
and/or death.
Do not install the SIMs unit if it will be exposed to rain or
other precipitation. Do not install the unit in a location
exposed to open ame or extreme heat. Do not touch the
unit with wet hands.

Due to our policy of continuous product innovation, some specications may change without notication.
Do not store or use ammable gas or combustibles near
the unit. Do not install the unit in a location that generates
oil, steam, salt, sulfuric acid, etc.
There is risk of product failure, re, explosion, physical injury and/or
death.
Replace all outdoor unit control box and panel covers.
If cover panels are not installed securely, dust, water or other foreign
objects may enter the interior of a disassembled unit, causing re,
electric shock, physical injury and/or death.
Do not cut, lengthen or shorten the cable between the
SIMs unit and the outdoor unit. Do not install the SIMs unit
in a location where the cable cannot be safely and easily
connected between the two units. Do not allow strain on
this cable.

LG SIMs 2.0 Terms and Conditions
In using LG SIMs 2.0 hardware and smart phone application you
agree to the LG SIMs 2.0 terms and conditions.
• LG SIMs 2.0 hardware and smart phone application are to
be used only with LG Electronics, Inc. inverter air conditioner
products.
• LG SIMs 2.0 hardware and smart phone application cannot be
sold/transferred/rented to any other parties.
• All data generated by LG SIMs 2.0 hardware and smart phone
application cannot be sold/transferred/rented to any other parties.
• A complete list of LG SIMs 2.0 terms and conditions is at
http://www.lg-dfs.com/sims.aspx
use the LG Smart Inverter Monitoring system
(SIMs) 2.0, Model PSWMOZ3. SIMs consists
of a hardware Wireless Local Area Network
(WLAN) module, an interface cable, and a free
application (app) for iOS and Android. The
user must supply a smart phone, either an
Apple iPhone or an Android phone. SIMs is not
optimized for tablets.
Before using SIMs, you must download and
install the latest version of the free SIMs
app from either the App store (iOS) or the
Play Store (Android). Be sure to download
the WLAN version of the app. There is also
a Bluetooth version (LG SIMs 1.0 [Bluetooth
Only]) on the Play Store, but the Bluetooth version will not work
with this WLAN SIMs module. Be sure to download LG SIMs 2.0.
Figure 1 shows the SIMs app and SIMs WLAN module in a typical
• LG SIMs 2.0 processes data in real time. If other functions of
the smart phone are used at the same time as SIMs, smart
phone resources may be insufcient for SIMs to process data
or the SIMs connection may be disconnected. Please use the
product with this in mind. Always use a smart phone with at
least the minimum recommended specications.
• The SIMs application may unexpectedly end due to insufcient
system resources.
• Transmission/reception data volume may increase according
to the number of indoor and outdoor units. SIMs response
speed may be slower for some smart phone specications.
• Wireless transmission/reception distance may be reduced or
communication may be disconnected due to the operational
environment (weather, electromagnetic interference or
physical obstacles).
• SIMs may not work correctly with rooted smart phones.
• As communication distance between the SIMs WLAN module
and the smart phone increases, smart phone WLAN output
may increase, causing greater drain on the smart phone
battery. During use, keep the smart phone as close as safely
possible to the SIMs WLAN module.

Due to our policy of continuous product innovation, some specications may change without notication.
Safety of personnel is the primary concern during all procedures.
Read and understand the safety summary at the front of this manual.
Read and understand this installation procedure before beginning
installation. Use the appropriate tools and acccessories during instal-
lation. Plan your work and do not work alone, if possible. Know how to
obtain emergency medical and reghting assistance.
Installation Sequence
To use SIMs, you must install the app on your smart phone and
you must connect the WLAN module to the outdoor unit. If you
have not yet installed the app, it may be more convenient to do so
before arriving at the job site. If desired, you can skip ahead to
the app installation section and return to WLAN module installation
when you are on-site.
Install the SIMs WLAN Module
The SIMs WLAN module must connect to the LGMV connector
on the outdoor unit’s circuit board. Most outdoor units have an
extension cable connected to the LGMV connector. To access the
extension cable you have to remove only the side handle cover.
Some outdoor units may not have the extension cable. If not, you
must remove the top cover of the outdoor unit and connect the
SIMs cable directly to the LGMV connector on the circuit board.
High voltages capable of causing death are used in this equipment.
Outdoor unit power remains connected during this procedure. Take
extreme caution not to touch electrical components or connections.
Failure to observe this warning can result in death or severe injury.
Some ODUs have an LGMV extension cable accessed by
removing the side handle cover. If the ODU does not have this extension
cable, access the LGMV connector by removing the top cover of the ODU.

Initial Setup
1. Tap the Setting button on the Start Screen.
2. The Setting screen displays. You can make selections for
Language (English or Korean), Temp Unit (Fahrenheit or
Celsius), and Demo Mode (On or Off).
3. Set these options as desired. Demo Mode is for demonstration only
and does not require a wireless connection to an ODU. Always set
Demo Mode to OFF when monitoring an air conditioning system.
Tap the Graph Info tab and
then tap the IDU tab to dis-
play IDU information in graph
format. You can “pinch” the
screen in and out to change
the time scale to display data
for a longer or shorter data
collection period.
Allow SIMs to run for 30 to 60
minutes to acquire enough
data to show system
operating trends.

The modular transmitter must be labeled with its own FCC ID number, and, if the FCC
ID is not visible when the module is installed inside another device, then the outside of
the device into which the module is installed must also display a label referring to the
enclosed module. This exterior label can use wording such as the following: “Contains
Transmitter Module FCC 10: BEJPCRCUDT2” or “Contains FCC ID: BEJPCRCUDT2.”
Any similar wording that expresses the same meaning may be used. The Grantee may
either provide such a label, an example of which must be included in the application for
equipment authorization, or, must provide adequate instructions along with the module
which explain this requirement. In the latter case, a copy of these instructions must be
included in the application for equipment authorization.
