This means that commandsignals below the set min do not result in any changes toflow volume.max settingThe max value corresponds to the flow volume thatis to flow when the command signal is 1.0 bar. The flowvolume is adjusted by the E adjuster, i.e. 1.0 bar inputsignal corresponds to 1.0 bar output signal for(customer flow volume)maxmin settingThe percentage figures refer to max . The settingmin = 0 is possible.
