• Reliable Performance: Equipped with high-sensitivity receivers and stable performance for consistent operation.
• Wide Application: Suitable for diverse applications including remote control of windows, entrances, garage doors, alarm systems, lighting, and lifting equipment.

3. Setup and Wiring

3.1 Power Supply

The receiver module requires a DC 12V power supply. Connect the positive (+) and negative (-) terminals of your 12V DC power source to the corresponding DC12V+ and DC12V- screw terminals on the receiver board.

3.2 Connecting Loads

The receiver module has four relay channels, each with Normally Open (NO), Common (COM), and Normally Closed (NC) terminals. You can connect various devices such as lamps, motors, or other electrical loads to these terminals based on your application requirements.

Image: Examples of wiring configurations for different types of loads. The diagrams illustrate how to connect lamps (1V-250V AC/DC), curtain motors (DC5V-30V), and garage motors (DC5V-30V) to the relay output terminals (NO, COM, NC) of the receiver board.

General Wiring Principles:

• Normally Open (NO): The circuit is open (disconnected) when the relay is de-energized and closes (connects) when the relay is energized.
• Normally Closed (NC): The circuit is closed (connected) when the relay is de-energized and opens (disconnects) when the relay is energized.
• Common (COM): This is the pivot point for the switch. Connect one side of your load to COM, and the other side to either NO or NC depending on desired behavior.

4. Operating Modes and Programming

The receiver module supports three main operating modes: Momentary, Toggle, and Latched. Each mode is programmed by pressing the learning button a specific number of times.

4.1 Clearing All Programmed Codes

Before programming new remotes or changing operating modes, it is recommended to clear all existing programmed codes. This ensures a clean slate for new configurations.

Image: To clear all codes, press the Learning Button on the receiver board 8 times. The indicator LED will flash 8 times, confirming that all existing remote controls are deleted successfully.

Procedure: Press the Learning Button on the receiver board 8 times. The indicator LED will flash 8 times, indicating that all codes have been successfully cleared.

4.2 Momentary Mode (Jog Mode)

In Momentary mode, the relay remains active only as long as the remote control button is pressed. Releasing the button deactivates the relay.

Image: Programming steps for Momentary mode. First, clear all codes by pressing the learning button 8 times. Then, press the learning button 1 time. Finally, press any button (e.g., 'A') on the remote control. The indicator light will flash, confirming successful programming.

Procedure:

1. Clear all existing codes (press learning button 8 times).
2. Press the Learning Button on the receiver board 1 time. The indicator LED will turn on.
3. Press any button on your remote control (e.g., button 'A'). The indicator LED will flash 3 times, then turn off, indicating successful programming.

4.3 Toggle Mode (Self-Lock Mode)

In Toggle mode, pressing the remote control button once activates the relay, and pressing the same button again deactivates it.

Image: Programming steps for Toggle mode. First, clear all codes by pressing the learning button 8 times. Then, press the learning button 2 times. Finally, press any button (e.g., 'A') on the remote control. The indicator light will flash, confirming successful programming.

Procedure:

1. Clear all existing codes (press learning button 8 times).
2. Press the Learning Button on the receiver board 2 times. The indicator LED will turn on.
3. Press any button on your remote control (e.g., button 'A'). The indicator LED will flash 3 times, then turn off, indicating successful programming.

4.4 Latched Mode (Inter-Lock Mode)

In Latched mode, pressing one button on the remote activates a relay, and it remains active until another specific button on the same remote is pressed to deactivate it. For a 4-channel module, typically one button turns a channel ON, and another turns it OFF.

Image: Programming steps for Latched mode. First, clear all codes by pressing the learning button 8 times. Then, press the learning button 3 times. Finally, press any button (e.g., 'A') on the remote control. The indicator light will flash, confirming successful programming.

Procedure:

1. Clear all existing codes (press learning button 8 times).
2. Press the Learning Button on the receiver board 3 times. The indicator LED will turn on.
3. Press any button on your remote control (e.g., button 'A'). The indicator LED will flash 3 times, then turn off, indicating successful programming.

4.5 Combined Operating Modes (Advanced)

The receiver module also supports combined operating modes for more complex control scenarios. These modes allow different channels to operate under different logic (Momentary, Toggle, Latched) simultaneously.

• 2CH Momentary + 2CH Toggle: Press the learning button 4 times, then press any remote control button.
• 2CH Momentary + 2CH Latched: Press the learning button 5 times, then press any remote control button.
• 2CH Toggle + 2CH Latched: Press the learning button 6 times, then press any remote control button.
• 2CH Latched + 2CH Latched: Press the learning button 7 times, then press any remote control button.

After pressing the learning button the specified number of times, the indicator light will turn on. Press any button on the remote control, and the indicator light will flash 3 times, confirming successful setting.

5. Maintenance

5.1 Remote Control Battery Replacement

The remote controls are powered by CR2016 or CR2025 coin cell batteries. If the remote's range decreases or it becomes unresponsive, the battery may need replacement.

Image: The remote control measures approximately 60mm in length and 30mm in width. The receiver board measures approximately 68mm in length and 48mm in width, with a height of 15mm. The remote control uses CR2016 or CR2025 3V batteries.

Procedure: Open the remote control casing, carefully remove the old battery, and insert a new CR2016 or CR2025 3V battery, ensuring correct polarity.

5.2 General Care

• Keep the receiver module and remote controls dry and away from excessive moisture.
• Avoid exposing the devices to extreme temperatures.
• Clean the devices with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.

6. Troubleshooting

• Device not responding to remote:
  • Check if the receiver module is properly powered (DC 12V).
  • Ensure the remote control battery is not depleted.
  • Verify that the remote control is correctly programmed to the receiver module. If unsure, clear all codes and re-program the remote.
  • Check for significant obstacles between the remote and the receiver that might impede the RF signal.
• Poor signal range:
  • While the product offers long range, dense materials like metal walls can significantly reduce signal penetration. Try to minimize such obstructions.
  • Ensure the receiver's antenna is not obstructed or damaged.
• Relay not switching as expected (e.g., momentary instead of toggle):
  • This indicates incorrect programming. Clear all codes and re-program the remote control to the desired operating mode (Momentary, Toggle, or Latched) following the instructions in Section 4.
• Relay type discrepancy: Please note that the relays used in this product are GuoKe brand, not Tongling, as some older product images might suggest. This is a functional detail and does not affect the specified performance.
