Does your controller run for about a minute then stop? Do you have a rain sensor connected to the controller?
If you answered yes to both questions you may have a faulty rain sensor or connection.
A quick fix is to hold down the “Rain Delay” button for about 5 seconds. SENS OFF should appear in the display indicating the rain sensor terminals are disabled.
Once you fix or repair the rain sensor you can hold the down the “Rain Delay” button for about 5 seconds. SENS ON should appear in the display indicating the rain sensor terminals are enabled.
