Step By Step Guide To Slim Duct Unit Installation
There are three methods 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
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 also through a 3 conductor
shielded cable.
Note: The wiring method is used for the below unit
