General Information
The filter control FS-21 meets the basic objectives for control of a one or two filter system
with pilot distributors or central control valves. The valve types are selected via configuration
and FS-21 automatically adjusts its operation sequence to the selected valve type. Both
decarbonisation filters and gravel filters can be controlled.
We recommend the use of our filter control FS-201 for more complex applications. This is
equipped with an enhanced range of functions.
