iAquaLink Schedule Acting Weird

HermanTX · Apr 3, 2024

Asking @PoolGate @MSchutzer @generessler @ajw22 or anyone else for their advice.

The pump schedule works fine. It turns on and off as scheduled and also moves to different speeds as scheduled.
However, the cleaner pump (AUX1), water feature pump (AUX2) will not function on their schedule. They will operate on demand using the app or the PC web interface. The ONE TOUCH system works - turns on when pressed and off based on runtime scheduled.
I have rebooted system, cleared all the schedules and then added back, even at different days and times. Nothing operates on scheduled time other than the filter pump relay.
It started randomly - I thought it got messed up with DST starting or when we had a power outage.
Any ideas on what to test?

UPDATE - I have tried to schedule Blower (AUX 3), pool light (Aux 4), or Spa Light (Aux 5) as all are on demand only. If I schedule for a single day, then the schedule does NOT work. If I schedule it for ALL days, then the schedule works.
So, something odd about scheduling a single day. My pool filter is scheduled for ALL thus I did not see any issues with it holding a schedule.

I have the RS8 PCB with rev T2 with 3.0 Antenna

That's pretty bizarre. One possible explanation is that memory used to hold the schedule (probably EEPROM) is "fatigued." Sectors can wear out in as little as 10k write cycles. Sounds like a lot, but we have no idea if the software is writing it routinely.

It's kind of like my 67-year-old brain. What comes back isn't always what went in.

Some things I'd try to work around the problem:

Reset the date (twice if it's already correct). Maybe this will re-initialize memory involving the day-of-week logic.
Try entering a schedule in Program Group B and then make Group B active. Idea is that this points all the DOW logic at a different area of memory that might be working better.
Do a full reset and re-enter all your programming. (Sigh...) I think we had a recent thread on schedule weirdness, and this fixed it. Maybe the reset lets the EEPROM self-heal somehow?

I haven't ever tried to schedule stuff for single days so I can't comment as to whether it works or not. Here's an old thread that might be of use:
iAquaLink programmed schedule change does not seem to take effect immediately?

In this thread there is a comment about issues when changing the schedule days from all to single days. The suggested work around is to add a new item to the schedule and then delete the old item rather than changing an item already in the schedule.

I'm not sure if this applies in your case, but it might be something to try. Also maybe clear out the entire schedule and start over?
