Frequently Asked Questions
Q: What voltages does the RF 433MHz wireless relay switch support?
A: The receiver operates on AC 75V to 240V, making it compatible with most standard mains voltages including 110V, 220V, and 240V systems. For programming/learning mode, supply 12V DC to the receiver input.
Q: How many trigger modes does this wireless relay switch offer?
A: The receiver supports six programmable modes: Momentary, Toggle, Latched, and three Delay timer settings (5 seconds, 10 seconds, and 15 seconds). Each mode is set using the onboard learning button, with LED confirmation flashes for easy setup.
Q: Can I pair multiple remote transmitters with one receiver?
A: Yes. The learning code system allows you to pair multiple transmitters to a single receiver. The receiver also supports additional 315MHz remote controllers, giving you flexible multi-remote setups. To clear all paired codes, simply hold the Learning Button for 8 seconds.
Q: What is the maximum load current for this relay switch?
A: While the relay is rated with a 30A peak marking, the rated continuous load current must not exceed 15A at 240VAC or 110VAC. Always ensure your appliance load stays within this limit for safe, reliable operation.
