\u3010Stable and Accurate\u3011 The temperature control range is -50\u00B0C to 99\u00B0C, with a maximum accuracy of \u00B11\u00B0C. Equipped with a 1m long NTC 10K temperature sensor, it is stable and reliable.\n\u3010Heating/Cooling\u3011 Heating mode (start temperature < stop temperature); Cooling mode (start temperature > stop temperature). Two relay outputs (one for heating and one for cooling modes).\n\u3010Maintain the Ideal Temperature\u3011 Easily switch between heating and cooling modes depending on the device you connect to the controller, and keep the devices at the desired temperature.\n\u3010Multifunctional Protection\u3011 Supports limit exceedance alarm/sensor failure alarm (EEE)/cooling control output delay protection. An alarm is triggered when the temperature exceeds the set temperature.\n\u3010Safety and Quality\u3011The fire-resistant ABS housing, large LCD screen, and three-button design make operation safer and easier to read and program.
