The controller CVC 3000 can be adapted to the specific application by choosing the appropriate function
depending on the connected components.
Automatic detection of the components
When switching on the controller the actual configuration of the connected components is checked
automatically.
Connected components (valves, sensors, pumps) are detected automatically and used and super-
vised until the controller is switched off.
The last mode of operation and the preselected values (e. g. for pressure, speed or time for switching
off) are stored.
In case of similar operation conditions it is possible to start immediately, if the preselections are chosen
appropriately.
The controller has five functions and one menu for configuration, see section ”Menu guide”. The several
functions include specific preselection possibilities and are adapted automatically with regard to the
connected components.
Depending on the connected components (valves, pump,...) some menu might not be active!
