While in operation the strengths of the system are clearly visible: be it through higher operating reliability; almost unlimited possibilities in building control; due to increasing communication demands; or security and energy efficiency. KNX intelligently solves issues dealing with the reduction of energy requirements: the goal being the individual room control of heating and air-conditioning. KNX regulates and controls global temperatures in connection with individual rooms and time periods. In non-occupied rooms the temperature is reduced, resulting in a maximum of energy savings.
