NC544-UTP CCA (Central Control Algorithm) is a part of Varta, a highly advanced automated control and optimization system. It is an advanced real-time controller that uses fuzzy logic algorithms to optimize the working conditions of heating, air conditioning and ventilation systems in commercial and residential buildings. It communicates with all the connected systems, taking input from sensors, and automatically calculates the best set point and sequence of operation. This helps to improve the energy efficiency of the system, reduce operational costs and maintain a healthy indoor environment.
