You have to mention the overview map options when you are creating  an 
overview map control.
Eg.
var overviewOptions = {
     layers: [overviewLayer],
     projection: "EPSG:4326",
     units: "m",
     maxResolution: "0.17578125"
  };
  overview = new OpenLayers.Control.OverviewMap(overviewOptions);
