What does the oven function "Fan Force Plus" mean?

This function works most efficiently when roasting or baking food all on the same shelf, with nothing above. This function is particularly effective for cooking lasagne as the oven will cook the filling and slowly brown the top, thus ensuring a well-cooked filling and golden brown top. It is also ideal for heating through cocktail food or mini pastries — to ensure that they are heated through and the pastry is crisp. Used at a low temperature this is a great function to hold food or just keep warm.
