Communication wire section
a. Power cable and communication wire must be fixed firmly.
b. Each indoor must be grounded well.
c. When power cable exceeds the range, increase the gauge appropriately.
d. Shielded layer of communication wires must be connected together and be earthed at single
point.
e. Communication wire total length cannot exceed 1000m.
a. Shielded layer of communication wire must be grounded at one end.
b. The total length cannot exceed 600m.
a) Indoor unit can be controlled by wired controller or remote controller.
b) When installation, the installer must set the unit due to the control type and wiring type.
Switchover between wired control master/slave unit /remote control unit, set when installation:
Note:
1. In the above figure, the state in the frame is set when out of factory.
2. The indoor controlled by master/slave wired controller and the indoor controlled by
individual wired controller are all wired controlled master indoor.
3. The remote receiver is equipped with a wire which can be inserted in CN21.
