• Branch line; line that is diverged from the main line.
• Sub-branch line: line that is diverged from the branch line.
NOTES
1 As shown above, if the centralised remote controls are connected to the control wiring between indoor unit and outdoor unit, it may not be able to
control the units even on the normal circuit, if the circuit connected to the central controller is out of order. Be sure to connect the central controllers
to the control wiring between the outdoor units.
: When the centralised remote controls are connected to the control wiring between the outdoor unit and indoor unit.
Line: Main line
Line: Branch line
Line: Sub-branch line
: Branch no.
The terminal for
Out/Out and the
terminal In/Out are
considered as the
same line.
쩻-쩾 excluded from this diagram
No sub-branch line
You cannot diverge the wiring
from the branch line. Be sure to
connect the unit by series
wiring. (Never diverge the
wiring from the branch line,
which may cause malfunction
of the transmission.)

How to count the branch wiring?
The control wiring between outdoor
units and the control wiring between
indoor unit and outdoor unit shall be
considered as main line. (We count
this as no. 1 branch), and we count
the branch line to no.
2 - 12, which is
diverged from the main line.
