The functions of the product are mainly classified into two categories: temperature function and humidity function; The temperature function is as follows: 1. Automatic working mode identification: The system automatically recognizes the working mode according to the start temperature/stop temperature; Start temperature > stop temperature, cooling mode 'C'; starting temperature < stop temperature, heating mode 'H'; 2. Cooling mode: When the detected temperature starting temperature, the relay is activated, the red light is on, and the refrigeration equipment starts to work; When the temperature of detection the stop temperature, the relay is off, the red light is off, and the refrigeration equipment stops working; 3. Heating mode: When the detected temperature the starting temperature, the relay is turned on, the red light is on, and the heating equipment starts to work; When the temperature detection stop temperature, the relay is closed, the red light is off, and the heating equipment stops working 4. OFE(-10.0 ~ 10.0) temperature correction function: The system works for a long time and deviations may occur. Through this function correction, the actual temperature = measured temperature + value calibration; How to set start/stop temperature: 1. On the running interface, press and hold "TM+" key for more than 3 seconds to enter the start temperature setting interface. The test can modify the parameters via the TM+ TM- key. When finished changing settings, wait 6 seconds to automatically exit and save; 2. In the running interface, press and hold "TM-" key for more than 3 seconds to enter the shutdown temperature setting interface. The test can modify the parameters via the TM+ TM- key. When finished changing settings, wait for 6 seconds to automatically exit and save; Humidity functions are as follows: 1. Automatic working mode identification: The system automatically recognizes the working mode according to the start humidity/stop temperature; Start humidity > stop humidity, dehumidification mode d; start humidity < stop humidity, humidification mode E; 2. Dehumidification mode: When the detected humidity start humidity, the relay is activated, the green light is on, and the dehumidification equipment starts to work; When the humidity detectedstop the humidity, the relay is off, the green light is off, and the dehumidification equipment stops working; 3. Humidification mode: When the detected humidity the starting humidity, the relay is activated, the green light is on, and the humidification device begins to work; When the humidity detected stops the humidity, the relay is turned off, the green light is off, and the humidification device stops working 4. RH humidity correction function (-10.0 ~ 10.0 ): The system works for a long time and there may be deviations. With this function correction, the actual humidity = measured humidity + calibration value; How to set start/stop humidity: 1. On the running interface, press and hold the "RH+" button for more than 3 seconds to enter the start humidity setting interface. The test can change the parameters by pressing the RH + RH- button. When the settings change is complete, wait 6 seconds to automatically exit and save; 2. On the running interface, press and hold "RH-" button for more than 3 seconds to enter the stop humidity setting interface. The test can change the parameters by pressing the RH + RH- button. When finished changing settings, wait 6 seconds to automatically exit and save
