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(directly connected to the indoor unit of line control) and others are the ine-
controlled sub units. Among them, the 4 indoor unit is this unit, the 3 indoor unit is the other DC models, 1 indoor unit
and 2 indoor unit are the AC models.The line control device is connected with the line-controlled main unit and DC
models through 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)
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.
