Remote controller wiring
• Strip off approx. 14mm cover of the wire to be connected.
• Twist wire of the remote controller to be connected with wire of the remote controller unit (or sensor), and press-fit
them with a wire joint. (Wire joints (White: 2 pieces) are included in the accessory of the main remote controller
(sold separately) or wireless remote controller kit (sold separately).)
• As the remote controller wire has no polarity, there is no problem if connections to indoor unit terminal blocks A
and B are reversed.
