I'm converting my irrigation system from a physical timer with physical valves to electronic control with solenoid valves.
Previously the pump would turn on automatically by the physical timer, which would cause the physical valves to switch between irrigation zones each time the system turned off/on.
I'm now at the point at which I have a basic 3-zone controller wired up to valves. However, I realize now that I need the ability to turn on/off the pump. Additionally, I believe that when a valve inevitably gets stuck closed, the pump needs to automatically turn off.
What pieces do I need to 1) have the irrigation controller control a 230V pump, and 2) prevent the pump from running if the valve doesn't open?
