I configured my 4 Button 1 Fader Echo Inspire Station to use Selection Raise/Lower on the fader. When no zones are selected on the station, however, moving the fader causes all zones in the space to raise or lower.
Description/Explanation of Issue
When the station does not see a selection to raise or lower, the fader will default to raising and lowering the entire space. This cannot be made null.
You may want to put the station and appropriate zones in a separate space so that the fader is unable affect undesirable zones. By putting the zones and station in a different space, the fader will only raise and lower those zones when no selection has been made.
