We are way off topic here. The Poster wants to add automation between his existing service and his existing pump. We are not changing loads or anything else. The problem is he does not have the service that the automation states it needs in the installation manual and without a lot of pictures or actually looking at it we really can't tell what he has. Yea it smells like a multi wire branch circuit (not the best thing to do in a residence by the way), but we really don't know that.
That said I really think you should have electrician come out and look at what you have and give you some options.
