- Confirm the power of whole system(Indoor Unit, Outdoor Unit) is
OFF, otherwise turn off.
- The communication cables connected to CEN.A and CEN.B terminal
should be connected to central control of Outdoor Unit with care for
their polarity (A-A, B-B ).
- Turn the whole system on.
- Set the group and Indoor Unit number with a wired remote control.
- To control several sets of Indoor Units into a group, set the group ID
from 0 to F for this purpose.
