a. Shielded layer of communication wire must be earthed at one end.
b. The total length cannot exceed 600m.
(4) Control type and the switchover
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.
4. For the indoor unit controlled by wired controller, if indoor unit is with the remote receiver, MUST pull out the
white wire from the remote receiver connector.
5. Correct procedure to shut off the unit: switch off the unit by the controller, then cut off the power source.
FORBIDDEN to cut off the power directly!
6. All the indoor EEVs are at open states which are set out of factory.

(1) AU48/ 60N, AU482 PCB indicator light explain:
LED1: failure light (when failure happened, flicker times indicate the corresponding failure code) explain.
LED2: Communication light/ debugging light (When SW01-4 be set to 0, LED2 is debugging light, LED2 flicker
times by 1Hz indicate model and 2Hz indicate the searched indoor numbers. If model and indoor numbers both
right, set SW01-4 to 1, LED2 become the communication light)
LED3: Power indicator light (It is light when power on and extinguishes when power off)

Model set up (Once selected, if
changed, need set it to 0 and power on
again set).
Once selected, LED2 change into the indicator
clamp between indoor and outdoor.
SW02 is defaulted all off.
