Step By Step Guide To Slim Duct Unit Installation
There are three methods to connect the wired controller to
the indoor units.
A. One wired controller controls one indoor unit; the indoor
unit connects with the wired controller through a 3 conductor
shielded cable.
A
B. One wired controller can control up to 16 sets of indoor
units (max); A 3 conductor shielded cable must connect
the wired controller and the master unit (the indoor unit
connected to the wire controller directly). The others connect
to the master unit through a 2 conductor shielded cable.
B
C. Two wired controllers control one indoor unit. The wired
controller that connects with the indoor unit is called the
master controller, the other is called the slave controller. The
master wired controller and the indoor unit (as well as the
master controller and the slave controller) are all connected
through 3 conductor shielded cables.
