Introduction:

The KF-900K intelligent controller adopts touch button technology, making it flexible and convenient to operate. The built-in sensor can monitor indoor temperature, humidity, VOC concentration, PM2.5 concentration, and CO2 concentration detection function in real-time. The controller output signal directly controls the start and speed of the fresh air fan, which can be widely used in residential, commercial, and industrial occasions, and can effectively improve air quality, creating a healthy, comfortable, efficient, environmentally friendly, and energy-saving living and working environment.
