Building technology with BONFIGLIOLI VECTRON GmbH Frequency inverters

Building automation is becoming increasingly important from the point of view of an energy consumption in keeping with requirements. The BONFIGLIOLI VECTRON GmbH frequency inverter contains a number of functions for the operation of pumps, fans and other drive applications in building technology. Examples include V-belt monitoring and the energy-saving speed and volume flow control with evoluted actual-value signal.
Load-dependent speed control via differential pressure is at present the most common way to control pumps and fans. This type of control can be realised without additional external controllers by using the technology controller which is a standard feature of BONFIGLIOLI VECTRON GmbH frequency inverters, see Figure A.



Individual adjustments of the technology controller allow you to run delta pc (Figure B) or delta pv (Figure C).



For economic and control technology reasons you should always try to realise deltapv.

The relationships between pressure p, volume V, output P and speed N as specified in the law of proportionality are shown in Figure D..
