Product functions are mainly divided into two categories: temperature function and humidity function; Temperature Function: 1. Automatic Mode Identification: The system automatically recognizes the working mode based on the start temperature/stop temperature. Start Temperature > Stop Temperature = Cooling Mode 'C'; Start Temperature < Stop Temperature = Heating Mode 'H'. 2. Cooling Mode: When the detected temperature is ≥ start temperature, the relay is activated, the red light turns on, and the cooling equipment starts working. When the detected temperature is ≤ stop temperature, the relay is turned off, the red light goes out, and the cooling equipment stops working. 3. Heating Mode: When the detected temperature is ≤ start temperature, the relay is turned on, the red light turns on, and the heating equipment starts working. When the detected temperature is ≥ stop temperature, the relay is turned off, the red light goes out, and the heating equipment stops working. 4. OFE (-10.0 ~ 10.0) Temperature Correction Function: As the system operates over time, deviations may occur. Use this function to correct the actual temperature = measured temperature + calibration value. How to Set 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 change parameters using the TM+ and TM- buttons. After finishing, wait 6 seconds for automatic 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 change parameters using the TM+ and TM- buttons. After finishing, wait 6 seconds for automatic exit and save. Humidity Functions: 1. Automatic Mode Identification: The system automatically recognizes the working mode based on the start humidity/stop humidity. Start Humidity > Stop Humidity = Dehumidification Mode 'd'; Start Humidity < Stop Humidity = Humidification Mode 'E'. 2. Dehumidification Mode: When the detected humidity is ≥ start humidity, the relay is activated, the green light turns on, and the dehumidification equipment starts working. When the detected humidity is ≤ stop humidity, the relay is turned off, the green light goes out, and the dehumidification equipment stops working. 3. Humidification Mode: When the detected humidity is ≤ start humidity, the relay is activated, the green light turns on, and the humidification device starts working. When the detected humidity is ≥ stop humidity, the relay is turned off, the green light goes out, and the humidification device stops working. 4. RH Humidity Correction Function (-10.0 ~ 10.0): As the system operates over time, deviations may occur. Use this function to correct 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. You can change parameters using the RH+ and RH- buttons. After finishing, wait 6 seconds for automatic 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 change parameters using the RH+ and RH- buttons. After finishing, wait 6 seconds for automatic exit and save.
