Check the virtual channel information of indoor/outdoor unit.
To execute power distribution without SIM/PIM, you should set virtual channel.
When bringing indoor unit's power from outdoor unit, set the 'Outdoor unit virtual
channel' information only.
( 'Outdoor unit virtual channel' is referring to watt-hour meter which is connected
to outdoor unit.)
When bringing indoor unit's power from the other device, not from outdoor unit,
set the 'Outdoor unit virtual channel' and 'Indoor unit virtual channel' information.
('Indoor unit virtual channel' is referring to watt-hour meter which is connected to
indoor unit.)
The number of virtual channel varies depending on the number of interface
module.
To execute power distribution, you need to check watt-hour meter value manually.
Power distribution using SIM/PIM is more accurate than using indoor/outdoor unit
virtual channel. Therefore, it is recommended to execute power distribution using
SIM/PIM.

of indoor unit, error may occur in the power distribution result.
You should set SIM/PIM channel information in the indoor unit if you want to execute
power distribution using SIM/PIM. If not, it means that you do not execute power
distribution. In this case, the power distribution result of the indoor unit will be '0'.
If the information of watt-hour meter connected to indoor/outdoor unit is changed,
consult with installation engineer.
DMS2 executes power distribution based on set information.
