Xylem hydrovar Instruction Manual

9
To increase the reliability of a system, (in the event of a Master controller failure) a second Master controller
can be used.
Full-featured possibility: Each pump is equipped with a Master controller.
In this mode it is possible to run all pumps in cascade serial mode and synchronous mode as well.
This conguration allows each pump to become the lead pump. This also ensures a proper operation if one
Master controller fails. In this case another HYDROVAR takes control. This ensures that the operating hours of
each pump will be the same to ensure even wear of the pumps.
