The XY-DTH1 features two independent relay outputs — one dedicated to temperature control (heating or cooling) and one dedicated to humidity control (humidification or dehumidification). Both relays operate simultaneously and independently, so you can run a heater and a humidifier (or any combination of devices) at the same time without interference.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum load each relay can handle?\u003c\/h4\u003e\n\u003cp\u003eA: Each relay output is rated for a maximum of 10A. Always ensure the connected device's current draw does not exceed this limit. For higher-load equipment, use a separate contactor or relay module rated for the required current, and use the XY-DTH1's relay as a trigger signal.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I connect and communicate with the module via UART?\u003c\/h4\u003e\n\u003cp\u003eA: The XY-DTH1 includes a UART interface that allows remote reading and writing of all parameters (start\/stop temperature, start\/stop humidity, correction values, relay enable). When real-time reporting is enabled, the module transmits current temperature, humidity, and relay status every 1 second to your connected terminal or microcontroller, making it ideal for data logging and automation integration.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the module remember my settings after power is lost?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. All configured parameters — including start\/stop temperature, start\/stop humidity, calibration values, and relay enable states — are automatically saved to non-volatile memory after 6 seconds of inactivity following any parameter change. Settings are retained even after power is disconnected.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Can the XY-DTH1 control both a heater and a humidifier at the same time?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes.
