Jandy iAqualink Programming Help

Moved from HERE

Related issue: I have an IAqualink system, with a wall mounted One Touch and remote capability. This system has been running flawlessly for years. Yesterday, the pool shut off before the programmed time and today it did not start at the programmed time. Both times I was able to manually override, so it's not a serious problem, imo.
Of course, I'm going away for a week next week so now I'm concerned.
Any ideas as to why this would occur? I checked the programs - everything is intact and programmed as input.
Would deleting the programs and rescheduling help? Or clearing the memory (Nuclear option!)?
Thanks in advance!

First, I would ask if you had a power failure that caused the system to go out. Second, have you verified that the time and date on your iAquaLink system is accurate.
Also, there is a battery on the back of the PCB that holds date and time info during a power failure but if that has become dead that can cause changes in your date & time or not reset if you have a power failure.

Thank you Herman. I can eliminate all of those possibilities - with the possible exception of the PCB battery, but Diagnostics is not reporting a low battery and no changes in the settings or real time/temp have been noted.

Thanks for feedback. I would access iAquaLink from my PC and go to the schedule screen. Take a picture of it with your phone. Then delete the schedules for the pool. then add new schedules for the pool and see if that works. It could be a quirk. With Jandy firmware, just hard to say. I had to delete some schedules for my cleaner and redo them when it acted up some months ago.
But it is always good to verify that your time & date on the system matches actual time as I see that as something easy to miss. Learned that via experience!!!
Hope that helps.

Another mystery solved.
Turns out that I inadvertently set the "TEMP MAINTAIN" on and that was apparently causing the snafu.
I switched it off and the system is running fine now.
Thank you, Herman and PoolGate for your input! Much appreciated!
