You would need a valve for each line that you'd like to control. The box then turns the valve on and off according to the conditions and your schedule.
Yeah. A manifold has multiple valves. Each valve has a solenoid that controls it. When powered, the solenoid will open the valve and let water pass. The sprinkler controller gets wired up to the solenoid on each valve so it can power the solenoid at the right time and let water pass through.
Yes swapping out is pretty straightforward. Take pictures of your existing setup and you should be good to go.crustydragon wrote: ↑ I have a basic bare bones Hunter controller that came with the house. Is it pretty easy just to swap out the wires to upgrade to this?
