I took a quick look at the datasheet and looks like the pump runs on either 230V or 380V. It can’t be directly connected to OpenSprinkler as a station (because each station only outputs 24V AC). Instead, you will need a pump start relay. If you are in the US, you can buy a pump start relay on Amazon or local home improvement stores. For example, this seems to work well:

Do make sure to check the horse-power ratings.
