Hello from Fredericksburg Texas. I think you can cancel the delay from the Home screen. Click on the "rain delay" icon and you should be able to cancel the delay from there. 

Hab einen schönen Abend, 

Hi Gary. I am a licensed irrigator in Texas and owner of an irrigation business. I'll be glad to help if I can. Wency gave some solid advice and instruction so maybe the issue has been solved. If not, then my first question for you is; Does the system function/water automatically but not in manual or does it not water at all?
