The controller CVC 3000 can be adapted to the specific application by choosing the appropriate function
depending on the connected components and the requirements of the application.
Automatic detection of the components
When switching on the controller the actual configuration of the connected components is checked
automatically.
Connected components (pump NT VARIO / VARIO-B, VSK 3000, valves) are detected automatically
and used and supervised until the controller is switched off. Switch off/on the controller to renew the
configuration.
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 features
five functions and one configuration menu, see section ”Menu guide”. Each
of these functions includes specific preselection possibilities and is adapted automatically with regard to
the connected components.
Depending on the connected components (e.g. valves) some menu items might not be active!
