With the “master” version of the Hyrdrovar, it is possible to connect up to 8 Hydrovar controller pumps together in
parallel. Complete lead/lag and auto alternation.
Reduction of overall cost for multi-pump system is possible using one “master” controller and several “basic” con-
trollers. The Hydrovar “master” will still control lead/lag, alternation.
