Figure 1: SIMs WLAN Module to Typical DFS System
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.
To use SIMs you must be a trained HVAC service technician
familiar with variable refrigerant flow (VRF) systems in general and
with LG's DFS 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.
Note:
The DFS air conditioning system must run for at least
15–20 minutes before data collected by SIMs 2.0 is valid
for troubleshooting.
Due to our policy of continuous product innovation, some specifications may change without notification.
