Safety Information
Please read and understand all safety instructions before installing or operating this device. Failure to follow these instructions may result in electric shock, fire, or property damage.
- Ensure power is disconnected before performing any wiring or maintenance.
- This device operates on DC 12V. Do not connect to higher voltage power sources.
- The maximum load is 7A. Do not exceed this rating to prevent damage to the receiver and connected devices.
- Installation should be performed by a qualified individual if you are unsure about electrical wiring.
- Keep the device away from water, excessive heat, and corrosive environments.
Setup and Wiring
The receiver module requires a DC 12V power supply and connects to the device you wish to control. The remote transmitter comes pre-coded, but can be re-programmed for different operating modes.
Receiver Wiring
- Power Connection: Connect a DC 12V power supply to the receiver's input terminals. Ensure correct polarity (positive to positive, negative to negative).
- Load Connection: Connect the device you intend to control (e.g., light, motor) to the receiver's output terminals. The receiver provides a passive output, meaning it acts as a switch in the circuit of your load. Consult the specific wiring diagram for your application.
- Secure Connections: Ensure all wire connections are secure and properly insulated to prevent short circuits.
Note: A detailed wiring diagram for your specific application may be required. The receiver typically has terminals for power input (DC 12V) and multiple relay output channels (Normally Open contacts).
Pairing Transmitter and Receiver (Intelligent Learning)
The receiver uses an "Intelligent Learning" method to pair with transmitters and set operating modes. The exact procedure may vary slightly, but generally involves:
- Enter Learning Mode: Press and hold the learning button on the receiver board until an indicator light (LED) illuminates or flashes.
- Transmit Signal: While the receiver is in learning mode, press the desired button on your remote control. The receiver's indicator light should flash or change state to confirm successful pairing.
- Exit Learning Mode: The receiver will typically exit learning mode automatically after a few seconds or after a successful pairing.
Refer to the specific instructions provided with your receiver for precise learning button location and indicator light behavior.
Operating Modes
The eMylo Wireless Remote Control Switch supports different operating modes, allowing flexibility in how connected devices are controlled. The factory default is "Inching" (Momentary) mode.
1. Momentary Mode (Inching)
In Momentary mode, the relay activates only while the remote button is pressed. Releasing the button deactivates the relay.
- Action: Press and hold button 'A' on the remote.
- Result: Connected device turns ON.
- Action: Release button 'A'.
- Result: Connected device turns OFF.
2. Latched Mode
In Latched mode, the relay toggles its state with each press of the remote button. One press turns it ON, the next press turns it OFF.
- Action: Press button 'A' once.
- Result: Connected device turns ON.
- Action: Press button 'A' again.
- Result: Connected device turns OFF.

Figure 2: Illustration of Momentary (Inching) and Latched operating modes. Momentary mode requires holding the button for activation, while Latched mode toggles the state with each press.
To change the operating mode, you typically need to re-pair the transmitter with the receiver, selecting the desired mode during the learning process. Consult the receiver's specific instructions for mode selection procedures.
Maintenance
Regular maintenance ensures the longevity and reliable operation of your eMylo Wireless Remote Control Switch.
- Cleaning: Wipe the receiver and transmitter with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement (Transmitter): The transmitter uses a 12V 23A battery. If the remote's range decreases or it becomes unresponsive, replace the battery. Open the battery compartment, remove the old battery, and insert a new one, ensuring correct polarity.
- Environmental Conditions: Ensure the receiver is installed in a dry, well-ventilated area, away from direct sunlight, extreme temperatures, and high humidity.
Troubleshooting
If you encounter issues with your eMylo Wireless Remote Control Switch, refer to the following common troubleshooting steps:
- Device not responding to remote:
- Check the transmitter battery. Replace if necessary.
- Ensure the receiver is powered on (check for indicator lights).
- Verify that the transmitter and receiver are properly paired. Re-pair if needed.
- Check for obstructions between the transmitter and receiver that might block the RF signal.
- Ensure the remote is within the effective operating range.
- Connected device not turning ON/OFF:
- Check the wiring connections to the receiver and the connected device.
- Ensure the connected device is functioning correctly when directly powered.
- Verify that the load current does not exceed the receiver's maximum 7A rating.
- Confirm the operating mode (Momentary/Latched) is set as desired.
- Short remote control range:
- Replace the transmitter battery.
- Relocate the receiver to a more open area, away from metal objects or other RF interference sources.
- Ensure the receiver's antenna (if external) is properly extended and positioned.
