Narrative:

During taxi out pack overheat message. First officer ran ECAM and reset pack, contacted maintenance into write up and new mrd (maintenance release document) were generated. En route right pack 'prsov high and comp discharge temperature 255 degrees.' pack outlet temperature -10 degrees. Left pack prsov mid and pack outlet temperature 45 degrees. Notified maintenance who advised we turn off hot trim air, right pack started to cool just then a right pack overheat ECAM, followed procedure and notified maintenance. Contacted maintenance by voice who suggested I could use my emergency authority/authorized for reset. I used because I wanted 2 packs for operations over high terrain. When I went to reset breaker left pack indicator momentarily went to yellow cross immediately reset breaker and all was normal, no indication of actual pack, shutdown pressure remained normal. Sent ACARS to maintenance. Asked for ACARS message to confirm circuit breaker grid locations. Reset breakers and after reset had 'right bleed flight light.' I advised maintenance who suggested we reset bleed flight and turn on pack after that the pack seemed to stabilize but did remain in high and ran at approximately 210-230 degrees 'comp discharge temperature.' remained greenband. Deferred hot trim air valve per maintenance and after block in reset circuit breakers for both packs and tested per maintenance. In the future it may be helpful to receive both grid and circuit breaker name in an ACARS note for resets.

Title: AN A319 ON TAXI OUT HAD R PACK OVERHEAT MESSAGE. RESET PACK. IN CRUISE AT FL310 HAD R PACK HIGH TEMP. DISABLED R TRIM AIR VALVE AND RESET CIRCUIT BREAKER AND REGAINED PACK.

Narrative: DURING TAXI OUT PACK OVERHEAT MESSAGE. FO RAN ECAM AND RESET PACK, CONTACTED MAINT INTO WRITE UP AND NEW MRD (MAINT RELEASE DOCUMENT) WERE GENERATED. ENRTE R PACK 'PRSOV HIGH AND COMP DISCHARGE TEMP 255 DEGS.' PACK OUTLET TEMP -10 DEGS. L PACK PRSOV MID AND PACK OUTLET TEMP 45 DEGS. NOTIFIED MAINT WHO ADVISED WE TURN OFF HOT TRIM AIR, R PACK STARTED TO COOL JUST THEN A R PACK OVERHEAT ECAM, FOLLOWED PROC AND NOTIFIED MAINT. CONTACTED MAINT BY VOICE WHO SUGGESTED I COULD USE MY EMER AUTH FOR RESET. I USED BECAUSE I WANTED 2 PACKS FOR OPS OVER HIGH TERRAIN. WHEN I WENT TO RESET BREAKER L PACK INDICATOR MOMENTARILY WENT TO YELLOW CROSS IMMEDIATELY RESET BREAKER AND ALL WAS NORMAL, NO INDICATION OF ACTUAL PACK, SHUTDOWN PRESSURE REMAINED NORMAL. SENT ACARS TO MAINT. ASKED FOR ACARS MESSAGE TO CONFIRM CIRCUIT BREAKER GRID LOCATIONS. RESET BREAKERS AND AFTER RESET HAD 'R BLEED FLT LIGHT.' I ADVISED MAINT WHO SUGGESTED WE RESET BLEED FLT AND TURN ON PACK AFTER THAT THE PACK SEEMED TO STABILIZE BUT DID REMAIN IN HIGH AND RAN AT APPROX 210-230 DEGS 'COMP DISCHARGE TEMP.' REMAINED GREENBAND. DEFERRED HOT TRIM AIR VALVE PER MAINT AND AFTER BLOCK IN RESET CIRCUIT BREAKERS FOR BOTH PACKS AND TESTED PER MAINT. IN THE FUTURE IT MAY BE HELPFUL TO RECEIVE BOTH GRID AND CIRCUIT BREAKER NAME IN AN ACARS NOTE FOR RESETS.
