1、LCD Display: With LCD display, the current mode and parameters of the module are clear at a glance, very clear, simple and practical. 2、Trigger Type: This thermostat supports key trigger control, high and low level trigger, and switching value control. It is applicable to most scenarios. 3、Accurate Work: When a normal heating or cooling operation is completed, the system starts to time T, and the system can only start another heating or cooling operation when T is greater than or equal to OPH. 4、Audible and Visual Alarm: When the actual temperature is greater than or equal to the alarm temperature, the system will turn on the audible and visual alarm, and then turn on the relay. 5、Data Transmission: After the temperature reporting function is turned on, the product will transmit the detected temperature to the terminal through UART at an interval of 1s for data collection.
