3. Setup and Wiring
3.1 Transmitter Battery Installation
The remote control transmitter requires two CR2032 batteries. To install or replace them, locate the screw port on the back of the transmitter, disassemble the casing, and insert the batteries according to the polarity markings.
3.2 Receiver Wiring
The receiver module features two wiring terminals for easy connection. It operates within a DC 3.6V to 24V range. Ensure correct polarity when connecting power and load.

3.2.1 Wiring for Electromagnets
When connecting to an electromagnet, ensure a diode (e.g., IN4007) is used in parallel with the electromagnet coil to protect the receiver from back-EMF. Connect the input power to IN+ and IN-, and the electromagnet to OUT+ and OUT- as shown in the diagram.

3.2.2 Wiring for LED Lights
For controlling LED lights, connect the DC power source to IN+ and IN-, and the LED light to OUT+ and OUT-. The output voltage will match the input voltage. The maximum load for LED lights is 3A.

4. Operating Modes and Programming
The receiver supports four operating modes, each programmed by pressing the learning button a specific number of times. The learning button is a small black button located on the receiver module (refer to Image 3.1).
4.1 Momentary Mode
In Momentary Mode, the output is active only while the remote button is pressed and held. Releasing the button deactivates the output.
- Programming: Press the learning button on the receiver 1 time. Wait approximately 3 seconds. Then, press any button on the remote control. The indicator light on the receiver will flash to confirm successful programming.

4.2 Toggle Mode
In Toggle Mode, pressing the remote button once turns the output ON. Pressing the same button again turns the output OFF.
- Programming: Press the learning button on the receiver 2 times. Wait approximately 3 seconds. Then, press any button on the remote control. The indicator light on the receiver will flash to confirm successful programming.

4.3 Latched Mode
Latched Mode uses two separate buttons on the remote: one to turn the output ON and another to turn it OFF. For the provided remote, this typically means the 'ON' button activates and the 'OFF' button deactivates.
- Programming: Press the learning button on the receiver 3 times. Wait approximately 3 seconds. First, press the 'ON' button on the remote control. Then, press the 'OFF' button on the remote control. The indicator light on the receiver will flash to confirm successful programming.

4.4 Delay Mode
In Delay Mode, pressing the remote button once turns the output ON, and it automatically turns OFF after a preset delay (5, 10, 15, or 20 seconds).
- Programming:
- For 5-second delay: Press the learning button 4 times.
- For 10-second delay: Press the learning button 5 times.
- For 15-second delay: Press the learning button 6 times.
- For 20-second delay: Press the learning button 7 times.
- After selecting the desired delay by pressing the learning button, wait approximately 3 seconds. Then, press any button on the remote control. The indicator light on the receiver will flash to confirm successful programming.

4.5 Clearing Stored Transmitters
To clear all stored transmitters from the receiver's memory, press the learning button on the receiver 8 times. The indicator light will flash to confirm that all previously programmed remotes have been cleared.

6. Maintenance
To ensure optimal performance and longevity of your Bkiyougo Remote Control Switch Kit, consider the following maintenance guidelines:
- Battery Replacement: Replace the CR2032 batteries in the remote control transmitter when its range decreases or it becomes unresponsive. Refer to Section 3.1 for instructions.
- Antenna Care: The receiver's antenna wire is delicate. Handle it with care to prevent breakage, which can significantly reduce the operating range. Avoid bending or pulling the antenna excessively.
- Cleaning: Keep the receiver module and remote control clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquids or abrasive cleaners.
- Environmental Conditions: Operate the device within the specified temperature range (-20°C to 80°C) and avoid exposure to excessive moisture or direct sunlight.
7. Troubleshooting
If you encounter issues with your Bkiyougo Remote Control Switch Kit, refer to the following common problems and solutions:
- Issue: Remote control not responding or short range.
Solution: Check the batteries in the remote control and replace them if necessary. Ensure the receiver's antenna is intact and not damaged. Obstructions like thick walls or metal structures can reduce range; try repositioning the receiver or reducing the distance. - Issue: Programming modes not setting correctly.
Solution: When pressing the learning button multiple times for different modes, ensure each press is rapid and distinct. Pauses between presses may cause the receiver to interpret it as a single press for Momentary Mode. Refer to Section 4 for precise programming steps. - Issue: Device remains ON or OFF unexpectedly after initial use.
Solution: This could indicate a short circuit or incorrect wiring. Double-check all connections according to the wiring diagrams in Section 3. If the issue persists, the receiver module may be damaged. - Issue: Output voltage does not match input voltage, or device does not function as a simple relay.
Clarification: This device provides power (matching input voltage) to the output when activated, rather than acting as a dry contact relay that simply connects two separate circuits. If your application requires a true relay function (e.g., switching a positive power line independently), you may need to integrate an external relay with this module. The receiver switches the negative side of the output.
