Outdoor units are of parallel connection via three lines with polarity. The main unit, central control and all
indoor units are of parallel connection via two lines without polarity.
There are three connecting ways between line control and indoor units:
A. One line control controls multiple units, i.e. 2-16 indoor units, as shown in the above figure, (1-5 indoor
units). The indoor unit 5 is the line-controlled main unit and others are the ine-controlled sub units. The
remoter control and the main unit (directly connected to the indoor unit of line control) are connected via
three lines with polarity. Other indoor units and the main unit are connected via two lines with polarity.SW01
on the main unit of line control is set to 0 while SW01 on other sub units of line control are set to 1, 2, 3
and so on in turn. (Please refer to the code setting at page 17)
B. One line control controls one indoor unit, as shown in the above figure(indoor unit 6-19). The indoor unit
and the line control are connected via three lines with polarity.
C. Two line controls control one indoor unit, as shown in the figure (indoor unit 20). Either of the line controls
can be set to be the master line control while the other is set to be the auxiliary line control. The master
line control and indoor units, and the master and auxiliary line controls are connected via three lines with
polarity.
When the indoor units are controlled by the remote control, switch over the modes by Switching Mode of
Line-Controlled Main Unit/ Line-Controlled Sub Units/ Remote-Controlled Types. The signal terminals needn't
to be equipped with wires and connected to the line control.
