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.
