Remote controller wiring
Indoor unit - FS unit control wiring
(1) The crossover wiring and central control wiring use 2-core non-polarity transmission wires. Use 2-core shield wires to
prevent noise trouble. In this case, close (connect) the end of shield wires, and perform the functional grounding for
the end of the shield wires which are connected to both indoor and outdoor units.
For the shield wires which are connected between the central remote controller and the
outdoor unit, perform the functional grounding at only one end of central control wiring.
(2) Use 2-core and non-polarity wire for remote controller. (A, B terminals)
Use 2-core and non-polarity wire for wiring of group control. (A, B terminals)
