Product features: The electronic thermostat power supply is DC 6-30V or 5V USB, the control load current is 10A (max), the test temperature range is from -50 to 110C, the temperature control accuracy is 0.1C, the refresh rate is 0.5 seconds, and the sensor length is 0.5 meters. Product function: This digital temperature control module has heating mode ("H") and cooling mode ("C"), with high temperature alarm delay (OPH), temperature correction function ranging from -10.0 to 10.0C (OFE), remote parameter reading and setting, real-time temperature reporting, and more. 2 Working modes: This electronic temperature controller offers two working modesheating mode (temperature lower than stop temperature) and cooling mode (temperature higher than stop temperature), with a range from -50C to 110C. High temperature control accuracy reaches 0.1C. Waterproof probe: The electronic thermostat is equipped with a 0.5-meter NTC10K probe made of stainless steel, which is waterproof, corrosion-resistant, easy to use, and durable. Use for: The electronic thermostat can be widely applied in smart home and industrial equipment, suitable for household appliances, office machines, audio devices, automotive systems, and more. Working mode/setting temperature/return temperature setting: 1. In the running interface, short press the "set" key to enter the quick setting interface. 2. After entering the quick setting interface, short press the "set" key to switch between parameters to set (work mode/set temperature/return temperature). 3. Use the "up" and "down" keys to adjust the parameter values; both short press and long press are supported. 4. Press and hold the "set" button for more than 3 seconds or leave the interface inactive for 6 seconds to save parameters and automatically exit the quick setting interface. Set /OPH/OFE (alarm temperature/delay start setting/temperature correction): 1. In the running interface, long press the "set" button for more than 3 seconds to enter the parameter setting interface.
