The ballasts are high in the cabinets (12" from the ceiling) with 6 muffin fans pulling air across them and out the cabinet. I was planning on setting the chiller high, say 81 or 82, just to help maintain the 2 deg swing you mentioned.

I really don't want to buy an $800-$1,200 1HP chiller if I can avoid it!

Actually, I am quite pleased with 79-82, I was expecting much worse!
