Programming Modes (Learning & Clearing)
With the receiver powered at 12V, use the Learning Button to configure your preferred operating mode:
- Momentary: Press Learning Button 1 time → LED flashes 1 time → press transmitter → LED flashes 3 times (success)
- Toggle: Press 2 times → LED flashes 2 times → press transmitter → LED flashes 3 times
- Latched: Press 3 times → LED flashes 3 times → press transmitter → LED flashes 3 times
- Delay 5s: Press 4 times → LED flashes 4 times → press transmitter → LED flashes 3 times
- Delay 10s: Press 5 times → LED flashes 5 times → press transmitter → LED flashes 3 times
- Delay 15s: Press 6 times → LED flashes 6 times → press transmitter → LED flashes 3 times
- Clear All Codes: Hold Learning Button for 8 seconds until LED flashes 3 times and turns off
⚠ Important Note: Although the relay is marked 30A/240VAC, this is the peak rating. The continuous rated load current of your connected appliance must not exceed 15A. Always follow the instruction manual for safe installation and use.

Frequently Asked Questions
Q: What voltage does the RF 433MHz wireless remote control switch support?
A: The receiver operates on AC 75V–240V, making it compatible with standard 110V and 220V/240V mains power supplies. It is suitable for a wide range of household and light industrial electrical appliances.
Q: How far does the 433MHz remote control transmit?
A: The transmitter has a wireless range of up to 100 metres in open-field conditions. Range may be reduced indoors or in environments with walls and obstructions.
Q: What is the maximum load current for this relay switch?
A: The relay is rated at 15A continuous load at 240VAC or 110VAC. The 30A marking on the relay refers to the peak/inrush current only — your connected appliance should draw no more than 15A continuously.
Q: Can I add extra remote controllers to this receiver?
A: Yes. The receiver supports a learning code system, which means you can pair additional 433MHz (or compatible 315MHz) remote controllers by following the programming steps outlined in the instructions.
Q: What operating modes does this wireless relay switch support?
A: It supports five modes: Momentary, Toggle, Latched, and two timed Delay modes (5 seconds and 10/15 seconds). You can switch between modes using the onboard Learning Button — the LED indicator confirms each mode selection.
