other than VRF, such as single split type, that are connected to the VRF System via convertors.

The S/V series and V-II/J-II series adopt different refrigerant system control and the electricity
charge apportionment function adopts different method reflecting the difference. So the same
operation condition for units may not yield the same result for S/V and V-II/J-II series.

The electricity charge apportionment function of VRF system can only be performed from 1 con-
troller or 1 gateway simultaneously.

Electricity charge apportionment error
Errors and their main causes related to electricity charge apportionment, detected by the BACnet
Gateway are described.

Generation conditions
Generated when a unit that does not send the information necessary for electricity charge appor-
tionment (non-communicating unit) is detected during the period electricity charge apportionment
data collection is performed.
Judgment, performed for the outdoor unit and the indoor unit, is based on whether there is no
communication for more than (0 minutes or not.
