Fresh Air intelligent controller (KF- 900A -Y2) adopts touch key technology, which is flexible and convenient to operate. The built-in sensors of the controller can monitor the indoor temperature, humidity, VOC, PM2.5 and CO2 concentration in real time. The output signal of the controller directly controls the startup and speed of fan.
It helps build a healthy, comfortable indoor environment while achieving high operational efficiency, energy conservation and eco-friendly ventilation performance for both living and working spaces.
Key Features:
LCD digital display real-time shows PM2.5, CO₂, VOC, ambient temperature and humidity data, clearly tracking indoor air quality (IAQ) status at a glance.
Intelligent auto ventilation adjustment based on detected air pollutant values to keep indoor air fresh and healthy all day long.
Equipped with child lock function to prevent accidental misoperation, ensuring safe use for families with kids.
