It provides a high fl exibility with regard to the place
of installation, range of available bus systems,
broadest HVAC control intelligence and functional-
ity, and respecting the building environment by
off ering the best EMC and harmonics behaviour in
the market.
The HVAC Drive off ers the highest effi ciency solu-
tion with both asynchronous motors and perma-
nent magnet motors. It can log and record it’s own
energy load profi le for both estimation and valida-
tion of actual energy savings.
