Smart LCD Color Screen VOC PM2.5 CO2 Temperature and Humidity Ventilation AC EC DC Fans HVAC Controllers

Introduction:

KF-900A-S intelligent controller is capable of real-time monitoring of indoor temperature and humidity, PM2.5, CO2 (optional), WIFI (optional). Connecting to WIFI can display the temperature and humidity values of the local meteorological station, with RS485 control. AC output signal directly controls the start and speed of the fresh air 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.
