Operation Introduction:

About Working Mode:

Momentary: Press the e on, the relay connects, release the e on, the relay disconnects.

Tole: Press once the e on, the relay connects, press the e on twice, the relay disconnects.

Latching: Press the e on A, the relay connects, press the e on B, the relay disconnect.

Time Delay Mode: Press the e control on, the relay connects; Start timing when release the e on, the relay disconnect automatically after 5s or 10s or 15s.


Clearing the Code:
Press the Learning on on the receivers for 8 times, the codes will be cleaned.
After cleaning the code, all the e control cannot work any more.

Learning the Code:Momentary
Press the learning key on the receiver once time, it comes into momentary setting mode.
Wait for a moment, the LED will be off , it comes into learning state.
Push the e on, LED indicator on the receiver board will f then come off.
After 3 seconds, the LED indicator will be on again, learning successfully.

Learning the Code: Tole
Press the learning key on the receiver twice time, it comes into tole setting mode.
Wait for a moment, the LED will be off , it comes into learning state.
Press the e on, LED indicator on the receiver board will f then come off.
After 3 seconds, the LED indicator will be on again, learning successfully.

Learning the Code: Latching
Note: When you choose for latching mode, in order to learn more e control, you need to learn two different on, the first time learning is for ON, the second time learning for OFF.
For example: on A = ON, on B = OFF
Press the learning key on the receiver tre time, it comes into latching mode .
Wait for a moment, the LED indicator on the receiver board will f then come off.
Press the e on A. LED f for 5 times.
Press the e on B. LED f for 5 times
After 3 seconds, the LED indicator will be on again, learning successfully.
A = ON, B = OFF .
