    Yes. With 220/240 coming in on two hot wires, you have 110/120 for each hot relative to the neutral. So, by wiring between one of the hots and neutral you get 110/120 for your pump.

    Before wiring up something that can kill you, I strongly recommend that you spend considerable time understanding how control circuits work and how to do them safely. If you don't completely understand what you are doing and why, get someone with suitable knowledge to help you.

    It requires a 4-wire cable into the control box to do it. Hot/Hot to the 230v items and Hot/Neutral to the 115v items.
