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 wired controller 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 wired controller) are connected
via three lines with polarity. Other indoor units and the main unit are connected via two lines or three lines
with polarity (If the PCB of indoor is DC, the wired controller needs to be connected to ABC, while the PCB
of indoor is AC, the wired controller only connects to BC.). 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.
B. One wired controller controls one indoor unit, as shown in the above figure (indoor unit 6-19). The indoor
unit and the wired controller are connected via three lines with polarity.
C. Two wired controllers control one indoor unit, as shown in the figure (indoor unit 20). Either of the wired
controllers can be set to be the master wired controller while the other is set to be the auxiliary wired controller.
The master wired controller and indoor units, and the master and auxiliary wired controllers 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.
