Turning back on for spring?

So, last fall I put the controller into standby mode and also manually shut the 4 valves in our system to help protect the lines from freezing. Today, I went back out and opened the valves (system still in standby) and all of the sprinklers came on - all zones at the same time - as I opened each valve. I played around with the app but could not get any of them to shut off. I finally manually closed the values again and put it back in standby mode. What am I doing wrong?

My guess is that the manual valve operation is an override for testing or flushing the valve without the controller. Double check your valve instructions.

Iā€™d guess you turned the little red knob on the solenoid valves, correct? If so you opened them. Tighten them back down and you should be good to go.
