Trigger Mode Guide

1. Momentary (Point) Mode – Press & hold the remote button to engage the relay; release to disconnect. Press the code-match button on the control board once to activate this mode.
2. Self-Locking Mode – Press the remote button once to engage; press again to disconnect. Press the code-match button twice to activate.
3. Interlock Mode – Press button A to engage the relay; press button B to disconnect. Press the code-match button three times and pair both A and B keys separately.
4. 5-Second Delay Mode – Press the button to engage; relay auto-disconnects after 5 seconds. Press the code-match button four times to activate.
5. 10-Second Delay Mode – Same as above, but with a 10-second auto-disconnect delay.

How to Copy / Clone a Remote

1. Clear the new remote: Press and hold both buttons simultaneously until the indicator light flashes continuously, then release. The code is now cleared.
2. Copy the key: Hold the original remote close to the new one. Press and hold the target button on the new remote, then press the corresponding button on the old remote.

Frequently Asked Questions

Q: What devices can I control with this 433MHz wireless remote control switch?

A: This 433MHz RF remote control switch is compatible with a wide range of 220V devices including water pumps, electric motors, lighting systems, electric doors, and automated curtains. As long as the device operates on 220V AC power and the load is within the relay's rated capacity, it can be wirelessly controlled.

Q: Does this wireless remote control switch come with a battery?

A: No, due to customs and shipping regulations, the battery is not included. You will need to purchase a compatible battery separately before using the remote control transmitter.

Q: How do I pair or copy the remote to the control board?

A: Use the built-in code-match button on the control board. The number of button presses selects your desired trigger mode (1 = Momentary, 2 = Self-locking, 3 = Interlock, 4 = 5-second delay). Once the LED remains lit, press the desired key on your remote to complete pairing. To copy an existing remote, clear the new remote's memory first, then hold both remotes close together and follow the copy steps outlined in the product guide above.

Q: What is the operating frequency, and will it interfere with other devices?

A: This switch operates at 433MHz, a globally recognized ISM (Industrial, Scientific, and Medical) radio band commonly used for wireless controls and home automation. At this frequency, interference with Wi-Fi (2.4GHz/5GHz) or Bluetooth devices is minimal under normal conditions.

Q: Can I use multiple remotes or control boards together?

A: Yes. The 433MHz protocol supports pairing multiple remotes to one control board, or one remote to multiple boards, depending on your setup. This makes it suitable for multi-point control in larger installations.
