ACCESSORIES
LG Smart Inverter Monitoring System (SIMS)
SIMS can be used to display and graph operational data for single zone systems and respective com-
ponents (indoor unit and outdoor unit). SIMS also displays error codes and a troubleshooting guide.
SIMs consists of a hardware Wireless Local Area Network (WLAN) module, an interface cable, and a
free downloadable application (app) for iOS® or Android™. The user must supply either an Apple® or an
Android smart phone; SIMs is not optimized for tablets, and only be used with LG single zone and Multi F
systems.
Only trained HVAC service technicians familiar with variable refrigerant flow (VRF) systems in general
and with LG's DFS products can use SIMS. The technician must understand inverter air conditioning
operation cycles, the meaning of the data displayed by SIMS, and how to use the data to troubleshoot
the system.
