6. Setup

6.1 Wiring Diagram and Connections

The receiver unit features screw terminals for power input and relay output. Refer to the diagram below for proper connections.

• GND: Input Ground (Negative power supply).
• VCC: Input Voltage (Positive power supply, DC 4V-12V).
• NC: Normally Close (Relay contact is closed when inactive, opens when activated).
• COM: Common (Common terminal for the relay contact).
• NO: Normally Open (Relay contact is open when inactive, closes when activated).

6.2 Operating Modes

The relay switch supports two operating modes: Momentary and Toggle. These modes are typically adjusted by a jumper on the receiver board (refer to the product's physical jumper settings if available, as specific jumper details are not provided in the data).

• Momentary Mode: Press and hold the remote button to turn the relay ON. Release the button to turn the relay OFF.
• Toggle Mode: Press the remote button once to turn the relay ON. Press it again to turn the relay OFF.

6.3 Clearing Stored Codes

To clear all previously learned remote control codes from the receiver:

1. Locate the learning button on the receiver board.
2. Press and hold the learning button for approximately 5 seconds.
3. The receiver's LED indicator will turn ON and then OFF, signifying that all codes have been successfully cleared.

6.4 Learning New Codes (Pairing Transmitter)

To pair a new remote control transmitter with the receiver:

1. Press the learning button on the receiver. The receiver's LED indicator will flash slowly, indicating it is in learning mode.
2. Press the desired button on the transmitter (remote control).
3. The receiver's LED indicator will flash quickly twice, then flash slowly again. This confirms successful learning.
4. Press the learning button on the receiver again to exit learning mode and turn off the LED indicator.

7. Operating the Device

Once the transmitter is paired and the receiver is wired correctly, you can operate your connected device wirelessly.

• If configured for Momentary Mode, press and hold the remote button to activate the relay. Release the button to deactivate.
• If configured for Toggle Mode, press the remote button once to activate the relay. Press it again to deactivate.

8. Maintenance

The Cuifati Mini Relay Switch is designed for low maintenance. To ensure optimal performance and longevity:

• Keep the receiver and transmitter clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid exposing the devices to water or high humidity.
• Replace the battery in the remote control when its range decreases or it stops responding. (Battery type not specified, typically small coin cell or A27/A23 type for similar remotes).

9. Troubleshooting

• Device not responding to remote:
  • Check if the receiver is powered correctly (VCC and GND connections).
  • Ensure the remote control's battery is not depleted.
  • Verify that the remote is properly paired with the receiver (refer to Section 6.4).
  • Check for any obstructions or excessive distance between the remote and receiver.
• Relay not switching:
  • Confirm that the load connected to the relay does not exceed the specified maximum current (7A recommended).
  • Inspect the wiring to the COM, NO, and NC terminals for secure connections.
• Short range:
  • Ensure the receiver's antenna is not obstructed or damaged.
  • Replace the remote control battery.
  • Minimize interference from other wireless devices.
