Answer
Hello Raul,

This type of message is telling you that you have a faulty solenoid or wire associated with zone 1.

Please check for a loose wire connection or a bad wire connection. If that does not solve the problem you can find a replacement solenoid to match your existing one. Turn the water off to the system and simply disconnect the two wire connections for the existing solenoid that is for zone 1 and replace it with the new one and reconnect the wires. Turn the water on and that should take care of your issue.
