Narrative:

Air carrier X at 11000' landing alb rted V270 center-alb. Fgt Y departure baf-een requesting 15000'. Procedure is for bdl approach to climb to 10000' and handoff to gardner sector. This sector is just north of center and the chester sector never sees or works these departures. The bdl approach controller mistakenly climbed fgt Y to 15000' and then put him on the center frequency (another mistake). Fgt Y reported on frequency leaving 11000' for 15000'. The conflict alert went off and this showed fgt Y approximately 1 mi from air carrier X at the same altitude, converging. I took immediate action by turning the traffic landing alb immediately to the left. The traffic passed with no further incident.

Title: ACR X HAD LESS THAN STANDARD SEPARATION FROM FGT Y. SYSTEM ERROR.

Narrative: ACR X AT 11000' LNDG ALB RTED V270 CTR-ALB. FGT Y DEP BAF-EEN REQUESTING 15000'. PROC IS FOR BDL APCH TO CLB TO 10000' AND HDOF TO GARDNER SECTOR. THIS SECTOR IS JUST N OF CTR AND THE CHESTER SECTOR NEVER SEES OR WORKS THESE DEPS. THE BDL APCH CTLR MISTAKENLY CLBED FGT Y TO 15000' AND THEN PUT HIM ON THE CTR FREQ (ANOTHER MISTAKE). FGT Y RPTED ON FREQ LEAVING 11000' FOR 15000'. THE CONFLICT ALERT WENT OFF AND THIS SHOWED FGT Y APPROX 1 MI FROM ACR X AT THE SAME ALT, CONVERGING. I TOOK IMMEDIATE ACTION BY TURNING THE TFC LNDG ALB IMMEDIATELY TO THE L. THE TFC PASSED WITH NO FURTHER INCIDENT.
