I have just picked up a Cal Spa 6 person Hottub Using the balboa C2000 spa Pack. the Tub has Ozone, 1 2 speed 4hp pump, and 1 single speed 4 hp pump. the problem i am having is that the control system will not turn on the second speed of the primary pump nor will it turn on the light. I can manually kick over the relays and get both to turn on, but the control system itself wont do this. The second pump and first speed of the primary pump work fine as well as the heat and ozone sytems.

Also the Control panel has the safety suction light lit, but no errors are coming up in the display panel, I was also wondering what the different codes FC, F2, F4, F6, F8 meant when you hit temperture and then jets quickly?

I can tell you what the "F" features are. They are the circulation cycles. How many times you want it to cycle in a 24 hr period are the numbers. eg.: "FC" - constant, "F2" - twice,"F4" - 4 times ect.. Hope this helps. I got a 1996 cal spa 2000, just about the same set up.
