Open Error

Line is ‘open’ and there is no connection.

Top Causes

● Occasionally, if newly installed, the head might throw that error as the controller was looking for heads during connection OR the previously installed heads were disconnected (either by you or by wire getting pulled underground).
● Faulty wiring or loose connections on your controller terminal connection points.
● Incorrectly enabled/disabled Master Valve in app’s System Setup page. Would be indicated by a 'Master Valve' open error.
● Wire from controller terminal to line has completely failed. Would be indicated by a 'Valve Zone' open error.

Check your cable connections based on the error. For example, if you see 'Open Line Error Zone 2,' check the wire coming in and going out of Zone 2 and make sure that they are securely connected. Clear the error and continue using the sprinkler or clear after testing and detecting.
