Really stupid question - but my old Sundance Teton spa is currently wired as 220V single speed. However, the side control is some retro fit and there are numerous other 'hints' that the previous owner had someone retro fit this spa. For example, the ozonator and spa lights don't work.

How would I determine if my pump and contros are actually for 2 speed but something is just miswired? I'm slowly learning the electronics of this spa as I have time - I'm familiar with electronics and electricity but spas are a new ball game for me.

Thanks for any help,
Chet

Just being nice and following up in case someone else falls into the same problem. Its a 220 2speed.

A few ppl little 'r'd with enough details to see that the pump was indeed a 2 speed just incorrectly wired. I was able to find the original wiring diagram by googling for the equipment part numbers (its an EM203T)
