Station # ERR Message CAUSE - The Station # ERR (for example 1 ERR) is a diagnostic message that appears when your controller is detecting a fault on that corresponding irrigation zone. SOLUTION - To determine the cause of this message it is necessary to follow a series of steps. Disconnect the faulting wire from the controllers screw terminal and switch it with a wire that is working. For example if zone #2 faults, disconnect the #2 wire from the controller and put it in the #1 screw terminal and put the #1 wire into the #2 screw terminal. Now try to run zone 1. If zone 1 now faults out, it is confirmed that there is a short in the wire from the controller to your zone valve, a short in the connections to the wire or at the valve solenoid itself. You can further confirm the problem is in the original #2 wire by now trying to run zone #2. If the wire connected to screw terminal #2 now turns on our original zone #1, it is further confirmation the problem is with the original #2 wire or connections. If the wire connections are good, the error message may indicate a bad solenoid.
