Wiring Diagram

Compatible Cable Types and Screw Terminals Wiring Configurations for DC/AC Devices and Motors

Power input: Connect DC 6V-30V to VIN (+) and GND (-)
Relay output (dry contacts): Four independent relays, each with NO/COM/NC
Compatible cable types: Single-Strand Hard Wire (BV), Stranded Hard Wire (RV), Stranded Flexible Wire (BVR)

Warning

Always disconnect power before performing any wiring or maintenance.
Do not exceed the maximum current rating of 10A per relay.
Ensure input voltage is within DC 6V-30V.
Keep the device away from moisture, water, and extreme temperatures.
If unsure about wiring, consult a qualified electrician.
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 receiver supports three operating modes. Follow the programming steps below to set the desired mode.

Momentary Mode

Press and hold a button → relay activates (device ON)
Release the button → relay deactivates (device OFF)

How to program:

Press the learning button on the receiver 1 time. Wait approximately 3 seconds.
Press button A on the remote control.
Press button B on the remote control. Pairing successful.

Toggle Mode

Press a button once → relay activates (device ON)
Press the same button again → relay deactivates (device OFF)

How to program:

Press the learning button on the receiver 2 times. Wait approximately 3 seconds.
Press button A on the remote control.
Press button B on the remote control. Pairing successful.

Latched Mode

Press ON button (e.g., A) → relay activates (device ON)
Press OFF button (e.g., B) → relay deactivates (device OFF)

How to program:

Press the learning button on the receiver 3 times. Wait approximately 3 seconds.
Press button A on the remote control.
Press button B on the remote control. Pairing successful.

Note: Latched mode typically requires a remote with at least two buttons per relay pair. For 4-channel receiver, buttons A/B control Relay 1, and C/D control Relay 2, etc.

Reset

To clear all paired remote controls from the receiver’s memory, press the learning button 8 times consecutively. All previously paired remotes will be cleared. After reset, re-pair remotes as needed. Wiring Configurations for DC/AC Devices and Motors

Troubleshooting

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

Device not responding to remote: Check transmitter batteries (replace if needed). Re-pair remote. Ensure no obstacles (metal objects, thick walls). Verify receiver power (indicator light on).
Relay not activating/deactivating correctly: Check wiring to NO/COM/NC terminals. Confirm correct operating mode (reprogram if needed). Ensure load does not exceed 10A.
Remote buttons not lighting up: Replace 12V battery.
Persistent issues: Reset receiver (press learning button 8 times) and re-pair.
