KNX Energy Management Application Examples Building Control Systems Private House or Flat A KNX installation in a private home or a flat makes it possible to control the lighting, blinds and heating. Furthermore it enables specific energy savings by recording and displaying the consumption of individual devices and rooms. Solution: Active energy savings thanks to intelligent components!

The internal clock actively accesses all the components of the KNX attaches a time stamp to all measured data, installation, and permits not only differentiated which allows precise time allocation. energy measurements but also active energysaving modes. Visualisation The Smartphone displays the energy consumption of the individual rooms (sockets and lighting). Knowledge of the energy consumption provides awareness and makes it possible for you to estimate whether your own energy consumption is high or low. This is the first step in taking control of your energy usage and providing incentives for reducing consumption. Next step is to set threshold values Measures M easu Online Electricity ✓ 342.2 mA Voltage ✓ 673 mV Consumption ✓ 159.3 kWh on the KNX Energy Meter, and if they are exceeded then part of the room lighting will be switched off. 2 | KNX Energy Management 06.2013 | Building Control Systems | Application Examples Convenient call up of current energy consumption with InSideControl App KNX Energy Meter Switch Actuator KNX InSideControl IP-Gateway Part list Product Qty Reference KNX Energy Meter 1 MTN6600-0603 KNX Switch Actuator 2 MTN647593 KNX InSideControl IP-Gateway 1 MTN6500-0113 Application example Light and socket-outlets Measures M easu Online Electricity ✓ Dining room 342.2 mA Voltage ✓ 673 mV Living room Consumption ✓ 159.3 kWh Bedroom KNX InSideControl IP-Gateway Switch Actuator Application Examples | Building Control Systems | 06.2013 KNX Energy Meter KNX KNX Energy Management | 3 Private Villa In larger residential units with different floors or a garage, the demands placed on an extensive KNX installation are greater. The requirements for energy management are also more exacting – you may also wish to include the use of gas and water in your consumption recording, for example.
