The intelligent air conditioning controller is equipped with NB-IoT/4G communication technology. It is directly linked to a wireless connection with the primary station and self-learn the air conditioning commands. Through the software platform, the controller sends power on/off commands to adjust the air conditioning temperature remotely formulates energy-saving operation strategy any time to achieve energy conservation in the base station. At the same time, it can monitor the environmental status of the equipment room, such as smoke, water immersion, access control, and temperature.
