Product features: the electronic thermostat power supply is DC 6-30V or 5V -USB, the control load current is 10A (max), the test temperature is from -50 to 110Celsius, the temperature control accuracy is 0.1 Celsius, 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 the function of high temperature alarm (""), delayed start ("OPH"), temperature correction function -10.0~10.0Celsius ("OFE" ), remote parameter reading/setting, real-time temperature report and more 2 Working modes: this electronic temperature controller has 2 working modes, heating mode (start temperature is lower than stop temperature) and cooling mode (start temperature is higher than stop temperature), range from -50Celsius to 110Celsius; The high temperature control accuracy reaches 0.1Celsius Waterproof probe: XY-T01 electronic thermostat is equipped with a 0.5-meter NTC10K probe, which is made of stainless steel, is waterproof and not easy to rust, easy to use and can last for a long time Use for: the electronic thermostat can be widely applied in intelligent home and industrial equipment, suitable for household appliances, office machines, audio, automobiles, etc. 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 the parameters you to set (work mode/set temperature/return temperature); 3. Use the "up" "down" key to the parameter value, and they support short press/long press; 4. Press and hold the "set" button for more than 3 seconds or without any button operation for 6 seconds , it will save the parameters and automatically exit the quick setting interface. Set /OPH/OFE (alarm temperature /delay starting setting/temperature correction): 1. In the running interface, long press "set" for more than 3 seconds to enter the parameter setting interface; Product model: XY-T01 Power supply: DC6.0-30v or 5v -USB Measuring input: NTC10K/B3950 Output type: relay output 10A Probe type: waterproof NTC probe High temperature alarm : sound-light alarm Delay start OPH: 0-9999 minutes Temperature correction: -10 to 10Celsius, actual temperature = measuring temperature + calibration value Colour:blue Material:Electronic component Size:About 68 x 42mm Probe's length: 0.5 m Package Contents: 2 x controller module Only the above package content, other products are not included.
