An operating pump will normally consume more

power the faster it runs – according to a curve

determined by the pump and application design.

VLT® HVAC Drive will detect situations where the

pump runs fast but is not fully loaded – and

thereby not consuming adequate power. This is

the case when water circulation stops, the pump

runs dry or when when pipes leak.
