Programming instructions:

1. Connecting the power supply
Connect the module to a 12V direct current source. Ensure that the polarity is correct.
As soon as the module is supplied with power, a status LED usually lights up to indicate that the module is ready for operation.

2.switch to learning mode and select mode
Press the learn button to switch the module to learning mode.
Switch to the desired mode (pin L/S1/T):

Current mode: does not connect two pins.
The relay is only active until a button is released.

On/off mode: connects pin2 and pin3 or S1 and T.
Pressing the respective button once switches the relay on, pressing it again switches it off again.

Interlock mode: connects Pin1 and Pin2 or L and S1.
A relay remains active until another button is pressed.

3. Pairing the remote control
Press a button on the radio remote control that you want to control with the relay while the module is in learning mode.
The receiver module recognizes the signal and saves it.
As a rule, the module indicates that the learning process was successful by the LED lighting up briefly or going out.

4.testing
Once the radio remote control has been programmed, you can press the buttons on the remote control to activate or deactivate the corresponding relays.

Resetting the receiver:
If you want to reset the programming, press and hold the learn button for approx. 8 seconds until the LED indicator goes out.

Scope of delivery:
