Recess Appointments

When the Founders put in the Constitution for the President to be able to appoint a person to Office in Congress is in recess, did they intend or was it understood to mean that all that has to happen is for the President to wait for a recess to appoint Officers without the required consent of the Senate? Or was it understood to be a mechanism for the President to fill a position that required immediate action that could not wait for the Senate to convene and consider, similar to the Clause in Article I section 10, that allows the Executive of a state to request Federal assistance in an emergency if the Legislature for that state is not in session to request it themselves?
