Marking on the wires causing the pump to run continuously

The wire tags indicate the two controlling
Wires are marked 24 volt so I attached them to the two connections in the controller marked 24 volt. This had the pump running constant.
Guessing I changed the two in the controller to the pump and neutral connections and all started working as it should.
No where does it indicate doing this

I bought the pump start in the US, bit live in Chile where we have 220v. Can I connect it or do I need a transformer to feed 110v
My pump is also made for 220v
Thanks.

Orbit

Our Pump start relay can handle 220v so there is no need for any special wiring methods.
