Introduction:

Fresh Air intelligent controller (KF-900M) 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 can be widely used in residential, commercial and industrial applications, and can effectively improve air quality, create a healthy, comfortable, energy-efficient living and working environment.
