Installation and operating instructions Wilo VR System 17
1 General
Installation and commissioning by qualified per-
sonnel only!
1.1 Intended use
The VR control device is for automatically control-
ling pressure boosting systems consisting of 1 to
4 pumps with integrated frequency converters of
the WILO- MVIE, MVISE, MHIE and HELIX VE series
or external frequency converters. These operating
instructions only apply to operation with WILO
pumps with integrated frequency converters.
If external frequency converters are used, the cor-
responding installation and operating instructions
are to be taken into account.
Water supply and pressure boosting in residential,
commercial and public buildings, hotels, hospitals,
department stores and for industrial systems are
the fields of application.
When used in conjunction with suitable signal trans-
mitters, the pumps offer low-noise and energy-
saving operation. The performance of the pumps
is adapted to the constantly changing require-
ments in the pressure boosting system.
