Set the refrigerant piping system, signal wires between
indoor-indoor unit, and those between the outdoor-outdoor
unit into one system.
Unify the power supply to all indoor units in the same
system.
Do not put the signal wire and power wire in the same wire
tube; keep some distance between the two tubes. (Current
capacity of the power supply: less than 10A--300mm, less
than 50A--500mm.)
Set the address of the outdoor unit in case there are parallel
multi-outdoor units.
