Question
I believe I have found a manual that may work for our Hardie Irrigation System, but I am not finding an answer to our issue. Our system is mounted outside and not inside, currently if I go to "set programming" the display unit flashes through the time (or day of the weekend) rapidly. I believe our system may be hard wired?? Could this be a simple fix?

Thanks, Jo Ann

Answer
I'm not sure it will fix it but, try using a hair dryer to dry out the controller. It may have gotten a little water in it and is making strange connections internally.
If you can find-out how to turn it off the power for a few hours that too may help.
