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 AC 85V-240V.
Keep the device away from water, moisture, 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 product is typically pre-programmed in Toggle Mode. Follow the steps below to change modes.

Momentary Mode (Mode 1)

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.
Press button A on the remote control.
Press button B on the remote control. Pairing successful.

Toggle Mode (Mode 2)

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.
Press button A on the remote control.
Press button B on the remote control. Pairing successful.

Latched Mode (Mode 3)

Press button A → Relay 1 turns ON, Relay 2 turns OFF
Press button B → Relay 2 turns ON, Relay 1 turns OFF

How to program:

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

Note: Latched mode provides alternating control between two relays. It requires a remote with at least 2 buttons for independent control of two relays.

Reset

To clear all programmed remote controls from the receiver’s memory, press the learning button 8 times. The indicator light will flash, confirming the reset. After reset, previously paired remotes will no longer work; re-program as needed. Various Wiring Modes for AC and DC Devices

Troubleshooting

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

No response from remote: Check remote batteries (2 x 12V). Ensure receiver is powered (AC 85V-240V). Verify remote is properly paired. Ensure within 50m range (walls may reduce signal).
Incorrect operating mode: Re-program the desired mode following the instructions.
Relay not activating/deactivating: Check wiring connections. Ensure load does not exceed 10A.
