Central Heating Problem - Potterton Flamingo 50?

I WOULD BE INCLINED TO SHUT ALL THE RADIATORS OF UPSTAIRS AND PUSH THE HEAT DOWNSTAIRS, BUT ONLY HAVE ONE RAD OPEN DOWNSTAIRS BLEED THE AIR OUT THEN MOVE TO YOUR NEXT RADIATOR BUT OPEN FULLY THE FLOW VALVE AND SHUT THE RETURN VALVE OF AND OPEN AGAIN 1.5 TURNS ONLY TO START BALANCING THE SYSTEM AND REPEAT THIS PROCEDURE UNTIL YOU ARE AT THE LAST RAD, THEN OPEN ONE BY ONE THE RETURN VALVE.
