<Synchronous twin system>
13-3. Remote Controller Wiring
• Strip off approx. 9 mm the wire to be connected.
• For single system, use non polarity, 2 core wire is
used for wiring of the remote controller.
(0.5 mm² to 2.0 mm² wires)
• For the synchronous twin, triple system, use
2-conre shield wire (Vinyl cord for microphone 0.5
to 2.0 mm²) to conform to the EMC standard.
Wiring diagram
∗ For details of wiring/installation of the remote
controller, refer to the Installation Manual enclosed
with the remote controller.
<Single system>
<Synchronous triple system>
∗ Use 2-core shield wire (Vinyl cord for microphone
0.5 to 2.0 mm² or more) for the remote controller
wiring in the synchronous triple system to prevent
noise problems. Be sure to connect both ends of
the shield wire to the earth.
∗ Connect earth wire for each indoor unit in the
synchronous triple system.

WARNING
For synchronous twin and synchronous triple systems, perform the following to confom to EMC standards.
