New JBJ Arctica 1/5th Chiller only has a 1 degree swing?

Maybe you can help. I bought a 1/10th JBJ chiller almost two years ago and it failed within 7 months bad temp probe. They warranted back in April 2012 and sent it back with a new probe and controller. Before the repair with the set point at 78 the unit would kick on at 79 and cool down and shut off at 77 but this repaired unit shuts off at 78 a one degree swing? They told me to mail it back and sent me back a new unit. Well with this new unit I traded it back where I originally bought it from for credit toward a new larger "Redesigned Model" a 1/5th but same thing again set point at 78 kicks on at 79 shuts off at 78 not 77! They had me take it back where I bought it and swap for another new unit which did the same thing too. At this point I gave up and just let it cool down 1 degree. Why would you think they are letting these units go with this problem or am I doing something wrong? I also have a jbj 1/3 HP unit (6 Years old) which works properly on the same closed loop system it cools down by two degrees.
