Product features: the electronic thermostat power supply is DC 6-30V or 5V micro-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 metersProduct function: this digital temperature control module has heating mode (\H\) and cooling mode (\C\), with the function of high temperature alarm (\ALA\), delayed start (\OPH\), temperature correction function -10.0~10.0Celsius (\OFE\ ), remote parameter reading\/setting, real-time temperature report and more2 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 0.1CelsiusWaterproof 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 timeUse 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 want to set (work mode\/set temperature\/return temperature);3. Use the \up\ \down\ key to modify 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 ALA\/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-T01Power supply: DC6.0-30v or 5v micro-USBMeasuring input: NTC10K\/B3950Output type: relay output 10AProbe type: waterproof NTC probeHigh temperature alarm ALA: sound-light alarmDelay start OPH: 0-9999 minutesTemperature correction: -10 to 10Celsius, actual temperature = measuring temperature + calibration valueColour:blueMaterial:Electronic componentSize:About 68 x 42mmProbe's length: 0.5 mPackage Contents:2 x controller moduleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
