ScreenLogic / EasyTouch Scheduling Problem

Edit: THinking about this though: why would the pump be priming itself when its not running a program ?

Dunno. I said it was a WAG.

The pump is doings something strange and that is why I asked if you changed any configuration setting?

Dunno. @Rocket J Squirrel mentioned it in this thread...

Double priming. D'oh!

I just realized I've been double priming my pump ever since I had my EasyTouch automation installed 2 years ago. My Pentair IntelliFlo VS pump has priming settings, and the ET has priming settings, and neither one overrides the other. They both run, first the pump's internal prime routine, then...

Mav,

I went back and looked at your schedules and your pump speeds..

I assume your Waterfall circuit turns a valve. The schedule shows the Waterfall Circuit running from 7 pm until 8 am..

But.. the pump needs some circuit to be on, so that the pump knows what speed to run. After 7:30 pm, there is no Circuit with a speed running, so the pump should just shut off... :scratch: I am puzzled how your waterfall works after 7:30... I assume, it does, so maybe the IntelliFlo3 does not shut off when the speed goes away, which would be different than all the other IntelliFlo pumps..

As a test, set your Pool Circuit to run 8 am until 8 am (7 days a week) and see if all your problems go away..

Thanks,

Jim R.

@Jimrahbe good observation. I did that to economize on schedules. The waterfall is in, lets call it position 2, which is more closed when the pump is running high speed. I simply leave it in the more closed position, even after all the pump schedules complete at 8:30pm so when the high speed kicks in at 7:30am-8:30am I don't have to use a separate schedule. When the speed goes to normal "pool" speed, the waterfall is more open to allow flow, otherwise no water comes out due to reduced speed.

I don't have ScreenLogic, but on the ET control panel, it's

Menu > Settings > IntelliFlo > Pump #1 > Priming

I set that to 0 minutes and let the pump handle the priming. I have no idea whether this will help your strange issue.

Interesting. I was willing to give it a shot, don't think it could hurt but I don't have that option, under Pump #1 mine is set to VSF and there is no priming option.
 
Mav,

Please do me a favor, and try my suggest to run the Pool circuit 24/7, just as a test.. It would not be much effort to try it and see what happens..

BTW... Pump 'speeds' do not count as schedules...

Thanks,

Jim R.

Not sure if I understand the suggestion @Jimrahbe , if the pool is running 24x7 then I wouldn't expect to have it running when its not supposed to because its always on, so there's no opportunity for the problem to occur? Maybe I don't understand your suggestion?

Mav,

Good point!!! :oops:

How about adding a speed in your EasyTouch, for your Waterfall Circuit, and then see what happens.

I 'think' this is the main cause of the problem you are having...

Thanks,

Jim R.

Sure, I can give that a whirl, so I just swapped out the Pool High circuit and assigned the pool high speed to waterfall. In the end I end up saving 1 schedule slot as a result, so I like this better regardless. So here's what I've got now....

Mav,

Your original schedules showed that your waterfall was set to run from 7:30 PM until 8:30 AM... This means it should have run all night!!! Did you want that, or was that a mistake??

That is not what you have now... :scratch:

Let's also talk about your SWCG timing, but not until we have eliminated any odd pump running issues..

Thanks,

Jim R.

@Jimrahbe , it was never really set to "run" all night because there was no flow associated, it was really just set to move the automatic valve to a particular position, and then leave it there for the morning, so that when the higher flow is enabled, less water comes out of the waterfall. Otherwise the PH goes bonkers. Hopefully that makes sense. In reality, what I have now is what I had before only I was controlling the valve and the flow separately.
 
Mav,

What you say makes perfect sense in normal situations.. :goodjob:

What I was looking for is some odd reason that your pump might be trying to run when it was not supposed to, and thought there might be a bug in the F/W that could cause the pump to run its last known speed..

The more I think about it, the less likely that would be..

I was just grasping at straws, as you have a pretty odd failure mode.

Please let us know the final solution, as it will help others in the future.

Thanks,

Jim R.
 
Thanks @Jimrahbe. Unfortunately, last night's experiment was not successful. I heard it come on at least once at 12:08am. I'm mostly frustrated by the fact that the time it is activating during the night seems to be different every night, that is very frustrating as it is seemingly random. The next step is either to just live with it or disconnect the rs-485 between the pump and the easy touch and see what happens when I run the schedules directly from the pump.
 
Mav,

It would be nice to fix the problem, if possible..

But... I have three pools that all run 24/7/365.. I do this because I like making a little chlorine all the time, and I like skimming all the time. I also like the look of the water when there is a little motion to the water. I have been doing this for well over 10 years..

Without any proof whatsoever, I believe that it is much better for the pump then starting and stopping it several times a day. All three pools have 3 HP IntelliFlo pumps, that run mostly at about 1200 RPM, as my pools do not have heaters or spas.. The pumps run today just like they ran when originally installed.. Everyone here will know, as soon as one of them fails... :mrgreen:

Since the pools run 24/7, I never worry about freeze protection.. (Not that is much of an issue in Florida.. :mrgreen: )

The cost to run at a low RPM is not even a rounding error in my electrical bill.. Well under $20 bucks...

In any case, it is a pretty low cost work around to your problem, if you can't get it fixed the right way..

Thanks,

Jim R.
 
THanks @Jimrahbe , its definitely an option I hadn't really considered before. Initially, my main concern would have been additional cost, but thanks to the efficiency of these Pentair pumps, youre right, the math works out to about $8 a month more than running it the 8 hours I do now, so it is an option. Still going to try and narrow down the issue a little further, but definitely not something I'm willing to pay good money to fix. Just ticks me off because the ET is only a few months out of the (not so great) warranty period.
