brand new and high qualityFeatures:Long press any button for more than 5s to switch the pairing mode (Touching mode/ Ap mode):Touching mode: The blue light flashes rapidly 3 times in a row, wait 1 second, and flash 3 times again quickly.AP mode: The blue light continues to flash quickly.Note: After the product is powered on, it enters the Touching pairing mode by default. If the pairing fails, please operate according to the APP prompts.The temperature function is as follows:1. Automatic recognition of working mode:The system automatically recognizes the working mode according to the start temperature/end temperature.When the starting temperature is greater than the ending temperature, the cooling mode is adopted; when the starting temperature is less than the ending temperature, the heating mode is adopted.2. Cooling mode:When the sensor temperature is greater than or equal to the initial temperature, the relay is turned on, the red indicator light is on, and the refrigeration equipment starts working;When the sensor temperature is less than or equal to the termination temperature, the relay is closed, the red indicator light is off, and the refrigeration equipment stops working.3. Heating mode:When the sensor temperature is less than or equal to the initial temperature, the relay is turned on, the red indicator light is on, and the heating device starts to work;When the sensor temperature is greater than or equal to the termination temperature, the relay is closed, the red indicator light is off, and the heating device stops working. Humidity functions are as follows:1. Automatic recognition of working mode:The system automatically recognizes the working mode according to the start humidity/end humidity.When the initial humidity is greater than the termination humidity, the dehumidification mode is adopted; when the initial humidity is less than the termination humidity, the humidification mode is adopted.2. Dehumidification mode:When the sensor humidity is greater than or equal to the starting humidity, the relay is turned on, the red indicator light is on, and the dehumidification equipment starts to work;When the sensor humidity is less than or equal to the termination humidity, the relay is closed, the red indicator light is off, and the dehumidification equipment stops working.3. Humidification mode:When the detected humidity is less than or equal to the initial humidity, the relay is turned on, the red indicator light is on, and the humidifying device starts to work;When the detected humidity is greater than or equal to the termination humidity, the relay is closed, the red indicator light is off, and the humidifying device stops working.
