Wiring Diagram

• VIN: Connect DC 5V-30V positive
• GND: Connect DC 5V-30V negative
• NO/COM/NC: Dry contacts for each relay (passive output)
• Connect device power circuit through relay contacts (e.g., power source to COM, device to NO for normally off)

Warning

• Always disconnect power before performing any wiring or maintenance.
• Ensure input voltage is within DC 5V-30V and load current does not exceed 10A per channel.
• Do not expose the device to moisture. Remote controls are not waterproof.
• Keep out of reach of children.
• Usually the receiver and transmitter have been paired in factory. If not, reprogram them.
• Reset before you want to change the operating mode.
• After reset, all remote controls cannot work anymore.
• Replace the battery in time when the remote transmitter voltage is low.

Operating Mode

The product is typically pre-programmed in Toggle Mode. Follow the steps below to change modes.

Momentary Mode

Press and hold a button → relay activates
Release the button → relay deactivates

How to program:

1. Press the learning button on the receiver 1 time. The indicator light will turn on.
2. Press button A on the remote control. The indicator light will flash once.
3. Press button B on the remote control. The indicator light will flash once. Succeed.

Toggle Mode

Press a button once → relay activates
Press the same button again → relay deactivates

How to program:

1. Press the learning button on the receiver 2 times. The indicator light will turn on.
2. Press button A on the remote control. The indicator light will flash once.
3. Press button B on the remote control. The indicator light will flash once. Succeed.

Latched Mode

Press button A → Relay 1 activates, Relay 2 deactivates
Press button B → Relay 2 activates, Relay 1 deactivates

How to program:

1. Press the learning button on the receiver 3 times. The indicator light will turn on.
2. Press button A on the remote control. The indicator light will flash once.
3. Press button B on the remote control. The indicator light will flash once. Succeed.

Reset

To clear all paired remote controls from the receiver's memory, press the learning button 8 times consecutively. The indicator light will flash several times and then turn off, indicating all paired remotes have been cleared.

Troubleshooting

If the receiver and transmitter cannot operate normally, try the following steps:

• Receiver not responding to remote: Ensure receiver is powered correctly (DC 5V-30V). Check remote battery (A27). Verify remote is paired. Clear and re-pair if unsure. Minimize RF interference or obstacles.
• Receiver not operating at 5V: Some units may require 5.5V or 6V for reliable operation. Try increasing input voltage within 30V limit.
• Remote stopped working after moisture exposure: Remote is not waterproof. Open casing, remove battery, dry completely. Replace if needed.
• Relay clicks but device does not activate: Check wiring to NO/COM/NC terminals. Ensure device has its own power supply. Verify device load does not exceed 10A.

Maintenance

• Keep receiver and remote controls in a dry environment.
• Avoid exposing remotes to moisture or direct water contact.
• Replace remote battery (A27) when range decreases or LED becomes dim.
• Ensure wiring connections remain secure over time.
