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.

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.

Office Floor
On a floor of an office building, efficient energy management involves determining
and displaying the energy consumption of the lighting as well as the gas and water
consumption. Furthermore, monitoring the grid quality makes it possible to ensure the
operational safety of all IT devices.

The Touch Panel displays the consumption of electrical
energy in individual rooms as well as the total energy
consumption. Gas and water consumption is also displayed. This gives you an overview of the total consumption on the floor. The PM3255 Meter additionally provides
information about the grid quality (cos phi), and thus
about the availability of the IT system. The Touch Panel
also shows any alarms which are active.
