Error Codes
LGMV software helps the service technician or commissioning agent
to troubleshoot system operation issues by displaying error codes
(Figure 65). These error codes can be seen on the main screen of
the LGMV software program. For an overview of unit error codes,
see Troubleshooting using Error Codes. For detailed information on
how to troubleshoot individual error codes, see the unit's service
manual.
The software is available in a high version with all of the listed
features The low version has all features as the high version without
Target High Pressure and Target Low Pressure values shown on
main screen.
Instead of connecting to the outdoor unit, there is the option to
connect to an IDU with a USB to RS-485 connector kit. When
connected through an IDU, data recording is not available.
This software can be used to both commission new systems and

".CSV" file and emailed to an LG representative to assist with
diagnostic evaluations.
