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 humidity, dehumidification mode d; start humidity 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
