## Discrepancy

FLT DECK TEMP CONTROL FULL WARM AND VALVE SHOWS FULL WARM BUT ONLY PUTS OUT COLD AIR.   SAMC TEXT: PER VERBAL FROM FLT CREW.  COLD TEMPS IN BOTH COCKPIT AND CABIN.  STANDBY W-NO HELP.  STANDBY ON DID HELP BRING TEMPS UP.  ACP BITE CHECKS ON ZONE TEMP AND AUX TEMP CONTROLLERS ZONE TEMP CONTROLLER FAILED AND REPLACED REF MM AND ACP TESTS.  ALL ZONE TEMPS OKAY.
