Hydrovar Pump Controller Installation & Operation Manual

Product Overview
in a multi-pump-system depends on the system requirements (i.e. in a 6 pump system 2 or more Master
controllers can be used to increase reliability, and up to 4 Basic controllers without control card.
Minimum requirement: 1 Master controller and the other pumps equipped with Basic controllers.
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 configuration 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.
