Wired Controller Wiring Instruction
There are four methods to connect wired controller to the
indoor units:
1. Group control shown as Figure A and D: One wired
controller can control up to 16 indoor units. 3 pieces of polar
wire must be used to connect the wired controller and the
master unit (the indoor unit connected with wire controller
directly). And other units connect to the master unit through
2 pieces or 3 pieces of polar wire depending on the indoor
units, please do follow the corresponding indoor unit
installation manual's instruction.
2. Individual control as shown Figure B: One wired controller
controls one indoor unit, and the indoor unit connects to the
wired controller through 3 pieces of polar wire.
3. Two wired controllers control one indoor unit as shown
Figure C. Either one of wired controllers can be set as the
master wired controller and the other as the slave wired
controller. The connection between Master and slave wired
controllers as well as wired controllers connecting to indoor
units all requires the 3 pieces of polar wire.
