## Discrepancy

WHILE CLIMBING OUT FROM PIT, THE CREW NOTICED THE CABIN TEMPERATURE WAS 95 DEGREES.  THE CREW TRIED THE TEMPERATURE CONTROL VALVE IN BOTH MANUAL AND AUTO MODES WITH NO EFFECT.  THE CREW DECIDED TO RETURN TO PIT.  MAINTENANCE INSPECTED AND REPLACED THE TEMPERATURE CONTROL VALVE IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 21-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
