Does your controller run for about a minute then stop? Is your Rain Sensor jumper wire missing?
If you answered yes to both questions your controller may be activating a rain delay.
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 add a rain sensor or replace the rain sensor jumper cable 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.
