Challenge:
- LG VRF systems will not report their active thermo state to the professional app nor local BACnet points.
- Thermo state feedback will always remain at "0".
Solution:
One possible workaround is to use the EV opening value as a proxy:
- LG EV opening values range from 0 to 1400.
-
0 to 40 means completely closed.
- Above 40 typically means that it is in Thermo On mode (actively heating or cooling).
Limitations:
- Even if opened, it doesn't mean the unit is in absolutely in "Thermo-On".
- EV is open sometimes during automatic procedures (e.g refrigerant recovery, defrost, etc).
