tuya Kidman Fresh Air System LCD Controller
Product Information
The Kidman Fresh air system LCD controller is an intelligent controller that adopts touch button technology for flexible and convenient operation. It is equipped with built-in sensors to monitor indoor temperature, humidity, PM2.5 concentration, and CO2 concentration in real-time. The controller can directly control the start and speed of the new fan, making it suitable for residential, commercial, and industrial environments. It effectively improves air quality, creating a healthy, comfortable, efficient, environmentally friendly, and energy-saving living and working environment.
Product Usage Instructions
- Switch: To open the controller and activate the fan operation, press the switch. The LCD will display the control interface. To turn off the controller and deactivate the fan output, press the switch again. The LCD will display “OFF”.
- Adjust Working Mode: Short press the “M” key to switch between automatic, manual, and timing working modes.
- Manual Mode: In manual mode, use the short button to adjust the wind speed of the fan and the exhaust fan.
- Timing Mode: In timing mode, the fan will run according to the set time and wind speed. You can set 4 periods per day from Monday to Sunday, totaling 28 periods.
- Automatic Mode: In automatic mode, the controller will automatically regulate the fan’s speed based on the air quality condition (PM2.5 and CO2 concentration).
- PM2.5 Concentration: The controller has different concentration set points for PM2.5. The set points are as follows:
- 80 µg/m3 or higher: Concentration ≥ (concentration-set point)
- 60 µg/m3 or higher: Concentration ≥ (concentration-set point)
- 40 µg/m3 or higher: Concentration ≥ (concentration-set point)
- 20 µg/m3 or higher: Concentration ≥ (concentration-set point)
- 0 µg/m3: Concentration = (concentration-set point)
- CO2 Concentration: The controller has different concentration set points for CO2. The set points are as follows:
- 600 ppm or higher: Concentration ≥ (concentration-set point)
- 400 ppm or higher: Concentration ≥ (concentration-set point)
- 200 ppm or higher: Concentration ≥ (concentration-set point)
- 0 ppm: Concentration = (concentration-set point)
