Troubleshooting
Problem
The LED on the centralized
controller is not turned on.
The LED on the centralized
controller flickers for over
2 minutes and the all ON/OFF
button is not operated.
The centralized controller
is not controlled.
Explanation/Solution
 Check a power failure.
 Check the communication cable
between the transmitter and the
centralized controller (R1,R2) is
connected to the R1, R2 terminal,
not to C1 and C2.
 Check the communication cable is
connected according to their polarity.
 Check whether the DS01 is pressed.
If you want to reset the previous setting,
disconnect the power of the centralized
controller and reset the DS01. If you do not
turn on the centralized controller again,
you can use it with previous setting.
