LG SIMS - Self Diagnosis Functions

The SIMs WLAN module and the smart phone app together provide monitoring and troubleshoot-
ing capability for LG Duct Free Systems. SIMs functions only with LG Duct Free products (Figure
113).
SIMs can display and graph operational data for the air conditioner system including the indoor
unit and the outdoor unit. SIMs also displays error codes and a troubleshooting guide. A full copy
of the LG SIMs Smart Inverter Monitoring System User's Manual is available on the www.lghvac.
com website.
To use SIMs you must be a trained HVAC service technician familiar with variable refriger-
ant flow (VRF) systems in general and with LG's Duct Free System products. You should
understand the inverter air conditioning operation cycle, the meaning of the data displayed by
SIMs, and how to use the data to troubleshoot the system.
Figure 114 shows a Multi F configuration used with the SIMs module and app. LG SIMs can
also be used with Single Zone one-to-one configurations such as the Single Zone Wall Mount
systems.
High voltages capable of causing death are used
in this equipment. Outdoor unit power remains con-
nected 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.
• The Duct Free System air conditioning system
must run for at least 15–20 minutes before data
collected by SIMs 2.0 is valid for troubleshooting.
• You must have the free SIMs app correctly in-
stalled on your smart phone before using SIMs.
• 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.
