I have calspa it is showing EC in thedisplay. I know it means economy mode, but how do I get it out of this mode? The manual does not cover it.
So far the only way seems to be by cutting the power and resetting the tub.

Also how does it get in this mode?

I just called my local Cal Spa dealer today and asked him this very same question because my manual didnt mention anything for the 5000 series control. He told me that to toggle between the normal and the economy modes was accomplished by first pushing the heat button followed by pushing the light button...I hope this helps it worked for me.

Tell me what system you have first then I might be able to help you.

look at the control system and tell me what it says.
