Not necessarily the controller...
Just went to a job on Friday....couldn't get to the controller so I used my station master to fire the valve...after 10 seconds it shut off....
The solenoid ohmed out just fine....so I checked the connections....regular wire nuts..rusted connections....replaced all wire nuts and rewired all correctly
It does not do it anymore....
