I have a hydro quip control box hooked up to a 230V motor. The box is wired for 110V. Is this an issue? The pump will run on low speed only. When checking the voltage I found approx. 115 from white to red, the same for white to black and no voltage between black and red. I have the wiring diagram and I verified that it is hooked up the 110 way. Should I switch the wiring over to 220?

The lines for 220 are already ran to the breaker box with a GFCI so adding the extra input to the controller would be no problem.
