Narrative:

A crew received a left bleed caution message after left engine start. Maintenance control issued a corrective action by incorrectly applying MEL 36-21-06 for the left bleed loop; rather than MEL 36-11-02 for the prsov and the associated left bleed caution message. Due to the incorrect MEL being applied; the aircraft flew for five days without the malfunctioning left prsov being secured closed and appropriate performance penalties applied; as required to comply with the correct MEL procedure. The incorrect MEL application was discovered by a flight crew during their preflight at an outstation.
