Signal Wiring Drawing
Outdoor units are arranged in parallel connection via three lines with polarity. The main unit, central control and all indoor
units are parallel connection via two lines without polarity.
There are three ways to make connections 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 master unit and others are the slave units. The remote controller and the master unit
(directly connected to the indoor unit of wired controller) are connected via three lines with polarity. Other indoor units
and the master unit are connected via two or three lines with polarity (If the PCB of indoor is DC, the wired controller
needs to be connected to ABC, but when the PCB of indoor is AC, the wired controller only connects to BC.). SW01 on
the master unit of line control is set to 0 while SW01 on the slave units of line control are set to 1,2,3 and so on, in turn.
(Please refer to the code setting page).
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.
