The functions of the product are mainly classified into two categories: temperature function and humidity function. The temperature function includes the following: 1. Automatic working mode identification: The system automatically recognizes the working mode according to the start temperature and stop temperature. If the start temperature is higher than the stop temperature, it enters cooling mode 'C'. If the start temperature is lower than the stop temperature, it enters heating mode 'H'. 2. Cooling mode: When the detected temperature reaches the start temperature, the relay is activated, the indicator light turns red, and the refrigeration equipment starts to operate. When the detected temperature reaches the stop temperature, the relay is deactivated, the red light turns off, and the refrigeration equipment stops. 3. Heating mode: When the detected temperature reaches the start temperature, the relay is activated, the indicator light turns red, and the heating equipment starts to operate. When the detected temperature reaches the stop temperature, the relay is deactivated, the red light turns off, and the heating equipment stops. 4. Temperature correction function (OFE -10.0 ~ 10.0): Over time, the system may experience deviations. Using this function allows for calibration, where actual temperature = measured temperature + calibration value. How to set the start/stop temperature: 1. On the running interface, press and hold the "TM+" button for more than 3 seconds to enter the start temperature setting interface. You can adjust the parameters using the TM+ and TM- buttons. After completing the settings, wait 6 seconds to automatically exit and save. 2. On the running interface, press and hold the "TM-" button for more than 3 seconds to enter the stop temperature setting interface. You can adjust the parameters using the TM+ and TM- buttons. After completing the settings, wait 6 seconds to automatically exit and save. The humidity function includes the following: 1. Automatic working mode identification: The system automatically recognizes the working mode according to the start humidity and stop humidity. If the start humidity is higher than the stop humidity, it enters dehumidification mode 'd'. If the start humidity is lower than the stop humidity, it enters humidification mode 'E'. 2. Dehumidification mode: When the detected humidity reaches the start humidity, the relay is activated, the indicator light turns green, and the dehumidification equipment starts to operate. When the detected humidity reaches the stop humidity, the relay is deactivated, the green light turns off, and the dehumidification equipment stops. 3. Humidification mode: When the detected humidity reaches the start humidity, the relay is activated, the indicator light turns green, and the humidification equipment starts to operate. When the detected humidity reaches the stop humidity, the relay is deactivated, the green light turns off, and the humidification equipment stops. 4. Humidity correction function (RH -10.0 ~ 10.0): Over time, the system may experience deviations. Using this function allows for calibration, where actual humidity = measured humidity + calibration value. How to set the 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. You can adjust the parameters using the RH+ and RH- buttons. After completing the settings, wait 6 seconds to automatically exit and save. 2. On the running interface, press and hold the "RH-" button for more than 3 seconds to enter the stop humidity setting interface. You can adjust the parameters using the RH+ and RH- buttons. After completing the settings, wait 6 seconds to automatically exit and save.
