Pairing Transmitters:
To pair a transmitter with the receiver board, follow these steps based on your desired operating mode. The receiver can store approximately 20 transmitters.
Figure 7: How to Program Operating Modes
- Momentary Mode (Press 1 time): Press the learning button on the receiver board once. The indicator light will turn on. Then, press the desired button on your remote control (e.g., 'A'). The indicator light will flash, confirming successful pairing for momentary mode.
- Toggle Mode (Press 2 times): Press the learning button on the receiver board twice. The indicator light will turn on. Then, press the desired button on your remote control. The indicator light will flash, confirming successful pairing for toggle mode.
- Latched Mode (Press 3 times): Press the learning button on the receiver board three times. The indicator light will turn on. Then, press the desired button on your remote control. The indicator light will flash, confirming successful pairing for latched mode.
- Mixed Mode (Press 4, 5, or 6 times): For advanced mixed modes (e.g., 2 momentary, 2 toggle; or 2 momentary, 2 latched; or 2 toggle, 2 latched), press the learning button 4, 5, or 6 times respectively. Then, press the corresponding remote buttons as instructed by the specific mixed mode configuration.
For a visual guide on programming the remote control switch, please watch the video below:
Video 1: How to Program Remote Control Switch. This video demonstrates the steps to program the receiver board for different operating modes, including momentary, toggle, and latched modes, using the learning button and remote control.
5. Operating Modes
The DieseRC wireless relay switch offers three primary operating modes, which can also be combined into mixed modes, providing flexibility for various control needs.
Figure 8: Operating Mode Explanations
- Momentary Mode: The relay remains activated only while the remote button is pressed and held. Releasing the button deactivates the relay. This is ideal for applications requiring temporary activation, such as a doorbell or a momentary gate opener.
- Toggle Mode: Each press of the remote button toggles the state of the corresponding relay. Press once to activate, press again to deactivate. This mode is suitable for lights or fans where you want to switch them on/off with a single button.
- Latched Mode: Pressing one button activates its corresponding relay and simultaneously deactivates any other active relays in the latched group. For example, pressing button 'A' activates Relay 1, and pressing button 'B' activates Relay 2 while turning off Relay 1. This is useful for selecting between multiple states, like opening or closing a garage door.
- Mixed Modes: The device can be configured to combine different modes across its four channels. For instance, two channels can operate in momentary mode, and the other two in toggle mode, providing highly customized control.

6. Maintenance
To ensure the longevity and optimal performance of your DieseRC Wireless Relay Remote Control Switch, consider the following maintenance tips:
- Keep Clean: Regularly wipe the receiver board and remote controls with a dry, soft cloth to prevent dust and debris accumulation.
- Avoid Moisture: Protect the device from water and high humidity, as moisture can damage electronic components.
- Battery Replacement: If the remote control's range decreases or its indicator light dims, replace the CR2 batteries. Ensure correct polarity.
- Secure Connections: Periodically check all screw terminal connections to ensure they are tight and secure, preventing loose wires and potential electrical issues.
- Operating Environment: Use the device within its specified temperature and humidity ranges to prevent premature wear.
7. Troubleshooting
If you encounter issues with your DieseRC Wireless Relay Remote Control Switch, refer to the following common problems and their solutions:
- Remote Control Not Responding:
- Check the remote control battery. Replace if necessary.
- Ensure the remote is within the effective operating range (up to 50 meters in open areas).
- Verify that the receiver board is powered on and its indicator light is active.
- Re-pair the transmitter with the receiver board following the instructions in Section 4.
- Relay Not Activating/Deactivating Correctly:
- Confirm that the wiring connections to the relay terminals (NO, COM, NC) are correct for your application.
- Check the operating mode programmed for the relay (Momentary, Toggle, Latched). Incorrect mode can lead to unexpected behavior.
- Ensure the connected device is functioning properly and its power supply is adequate.
- Short Range or Signal Interference:
- Ensure the receiver's antenna is not obstructed or damaged.
- Minimize obstacles (thick walls, metal structures) between the transmitter and receiver.
- Avoid placing the receiver near other strong RF signal sources that might cause interference.
- Resetting the Receiver: If persistent issues occur or you wish to clear all paired transmitters, press the learning button on the receiver board 8 times. The indicator light will flash, confirming the reset. After a reset, all transmitters must be re-paired.
