Zone 1 works but no others

I have a Hunter Pro-C system. Worked fine until this spring after my irrigation company opened it up for summer. He said the control panel was going so I bought a new one. The pump will come on when I manually start Zone 1 but it will not activate for the other zones. The control panel shows Zone 2 and the time but the pump will not come on. Help?

I never see pumps where I live but I'm familiar with your controller. I've literally ran across only 1 job that had a pump in 20 years.

On the Pro-C there's an option to turn on or off the pump for each individual zone. I doubt you've turned them off but take a look anyway.

If they're on check the voltage at the pump/master valve terminal while it shows number 2 running. Do you have power?

If you have power then the problem's down the line somewhere. I'd only be speculating as to what. Pump relay, pump, filter, do you need a delay between zones. Can you hear the pump running while 2 is on?

Are the flow controls open on all the valves.

Are all the shut off valves open?

Are the valves themselves getting power?

Well that's about all I have. Someone else will have more.

Good luck!
