LG Thermo On State Not Available


  • 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".


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).


  • 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).
