About Working mode:

Momentary: Press the remote button, the relay connects, release the remote button, the relay disconnects.

Toggle: Press once the remote button, the relay connects, press the remote button twice, the relay disconnects.

Latching: Press the remote button A, the relay connects, press the remote button B, the relay disconnect.

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 remote button, LED indicator on the receiver board will flash then come off.

After 3 seconds, the LED indicator will be on again, learning successfully.

Learning the Code: (Toggle)

Press the learning key on the receiver twice time, it comes into toggle setting mode.

Wait for a moment, the LED will be off , it comes into learning state.

Press the remote button, LED indicator on the receiver board will flash 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 remote control, you need to learn two different button, the first time learning is for ON, the second time learning for OFF.

For example: Button A = ON, Button B = OFF

Press the learning key on the receiver triple time, it comes into latching mode .

Wait for a moment, the LED indicator on the receiver board will flash then come off.

Press the remote button A. LED flash for 5 times.

Press the remote button B. LED flash for 5 times

After 3 seconds, the LED indicator will be on again, learning successfully.

A = ON, B = OFF.
