pentair screen logic not following schedules

[saggi432]

Hello Everyone,
i have a pentair screen logic interface for my pool.. it was working fine previously however off late i have been noticing that its not able to follow the schedule for "low pool" or "high pool" settings .. the filter pump runs continuously ignoring the schedule settings.. i am quite novice to the pentair pool system so trying to learn the details so that i can troubleshoot the problem.. i have tried switching to service mode during which the filter pump turns off fine.. i was also able to map the aux settings.. like aux for pool high aux2 for air.. aux3 for lights etc.. but i am not able understand why the system keeps ignoring the schedule when i switch the mode to auto from service..

any advice from the experts would greatly help..

thank you for your time.

Can you check if the screen on the pump reads"Display not Active" and a picture of you screen logic schedule screen?

432,

If you have the EasyTouch lite, then you only can have a max of 4 schedules.

If you have the standard EasyTouch, you can only have a max of 12 schedules. This includes any egg-timers that are not set to the default of 12 hours.

The problem is that ScreenLogic will allow you to enter a bazillion schedules, but never tells you they will not work.

Show me a pic of the front of your EasyTouch, showing the display and all the buttons.

Show me a screenshot or just tell me all of your schedules.

I doubt anything is wrong with your system other than the programming.

Thanks,

Jim R.

That’s correct it does say “Display not active”

Below is the screenshot of my schedule and egg timer as I can see from the app

I am pretty new so I am a bit confused between the egg timer and schedule wondering if I really need to have the egg timer ?

432,

You have a 'Lite' version of the EasyTouch. This means you can only have 4 total schedules, including any egg-timers not set to 12 hours.

You have the Pool Low egg-timer set to 9 hours so that is one schedule.
You have Pool low scheduled to run 8 am until 6 pm, so that is your second schedule.

I suspect that you are manually turning on Pool High by pushing the "F" button. (Not how it should be done..)
I suspect that Pool High runs at a higher faster speed than Pool Low.

When the pump sees two speeds at the same time, it will always run the faster one.

If you manually turn on Pool High, it will run for 12 hours before shutting off due to the egg-timer. This makes the pool low schedule useless when pool high is on. Having a circuit called Pool high does not make a lot of sense, if it not scheduled.

Most people do not need egg-timers.. The egg-timer is used when you want to manually turn something on, and you want it to automatically shut off after X hours or minutes.

Schedules have a start time and a stop time.

Tell me what your goal is.. Tell me what speeds you want the pump to run at what times, and I'll post a schedule that should work...

Another problem with ScreenLogic is that if you add a bunch of schedules and then delete them, then don't always go away in the EasyTouch. So, ScreenLogic may show one schedule, while inside the EasyTouch there might be two schedules. You can check this out by using the little LCD and look at your schedules and ensure the ones on the EasyTouch match the ones in ScreenLogic.

Edit... Do you have a saltwater pool with a salt cell???

Thanks,

Jim R.

Thank you for the detailed notes..
The "F" button seems to be on all the time not sure if the maint guy turned it that way by mistake, does that mean that i dont need it when i have schedules in place? does the "F" also indicate "low pool" ?

from the description it looks like below is the mapping.. of the circuits. most of them have "onfreeze" turned "off"
main ="spa"
main(aux1) = "air blower"
main(aux2) = "for lights"
main(aux3) = "high pool"
main=pool(pool low)

Thats correct i have variable speeds configured for the pump(intelliflo pool low) by the previous owner one for each... spa,pool low, pool high and pool or spa active heater..

my goal is to have 2 schedules one for "low pool" and one for "high pool" .. perhaps use "high pool" when more circulation is needed (for example: when chemicals are added by our maint guys) and "low pool" during the normal days..

i recently moved to the home so i am trying to understand my pool more.. so pls correct me in my approach .

432,

The 'F' button light will be on anytime the system is in the Pool or Spa mode. Currently it should be on at 8 am and off at 6 pm..

So based on your single schedule, your pump should start at 8 am and turn off at 6 pm. This assumes no one turns on Aux 3 (pool high) or manually pushes the 'F' button.

Please set the egg-timer for Pool Low to 12 hours. (The Default)

Before we change any other schedules, let's make sure your system is working like it should.

1. Push the "reset' button on the front panel. This is like rebooting a PC, it will not erase anything. (Do this between 8 am and 6 pm)
2. Let the system come back up on its own. It might take 10 minutes or so, so don't worry if it takes a little while.
3. Do not push the 'F' button and do not push the Aux 3 button.
4. Ensure the system starts and is running in the AUTO mode. It should run at your Pool low speed. It should never run at Pool high speed. It should turn off at 6 pm.

Please let me know how the above test works..

What speeds are assigned to the pump for the following circuits???

Spa
Pool low
Pool high
Pool or Spa active heater..

Just for reference... I run my pump 24/7 at about 1200 RPM most of the time. This costs me less than $20 a month. I do this because I have a saltwater pool and like making a little chlorine all the time and I like skimming all the time. I also like the look of my pool when there is a little water motion. I personally think it puts less wear on the pump vs. starting and stopping each day, but have no actually proof that is true.

Do you have a pool cleaner?? If so, is it a suction side cleaner, a pressure side cleaner, or a low voltage robot? If you don't know, show us some pics of the cleaner and your equipment pad.

Thanks,

Jim R.

Sure let me follow the steps and get back to you .. thank you again!

The pool is a 13500 galon pool with 467 sq ft area.. dimensions are 35x19.. i do have a aiper pool cleaner(with dual scrubbers) which i use everyday to clean the floor of the pool for leaves and other dirt but usually the pool is clean...

below are the speeds i have.

Spa: 3200
pool low: 2500
pool high: 3500
Pool or Spa active heater: 3500

432,

It is your pool and you can run it however you want...

But... 2500 RPM is pretty fast for your low speed... and, the pump can only run at 3450, so you are running an IntelliFlo at full speed, which also seems way too fast to me.

After we make sure your system is working like it should, I would suggest that you think about reducing your pump speeds.

Thanks,

Jim R.

I agree ..
Many thanks to you.. . i think now i can see that the i am able to use my schedule effectively..
i have reduced the the "low pool" to 1200rpm and kept it running for 20hours and for the rest of the 4 hours i have started the "spa" with the same rpm... high pool and Pool or Spa active heater to 2500rpm for now but dont have a schedule for them. i want to test this config for a week and see how it works before finalizing ... do i need to turn "onfreeze" to "on" ?

432,

The only thing that needs freeze control is the Pool Circuit (named Pool low) and the Spa Circuit.

This is because when the freeze control kicks in, your automaton will switch back and forth between the Pool mode and the Spa mode.

If you run 24/7 in the Pool mode, with the spa spilling over into the pool, I doubt you would really need freeze control at all.

Here is an example of a schedule to change speeds.. Say you want to run the pump for a total of 12 hours and Pool High for 2 hours.. (Just an example...)

Your schedule would look like this...

Pool Low = 8 am until 8 pm... Pump speed is 1200 RPM
Pool High = 5 pm until 7 pm... Pump will run at 2500 RPM..

This is how it will work.. At 8 am the pump starts and runs at 1200 RPM until 5 pm when the speed will increase to 2500 RPM. The pump will run at 2500, until 7 pm, when the pump will slow down to 1200 RPM, until it shuts off at 8 pm..

The above example shows how when the pump sees two or more speeds, it will always run the fastest one.

Thanks,

Jim R.

Got it.. currently with pool low or spa running at 1200RPM i dont see spa spilling over into the pool.. i may need to change spa to 2500 may be(?) to get that spill over.. let me do some tests..

 

[Jimrahbe]

432,

In the Spa mode, you better hope that the spillover never works...

Your spillover should only work when the system is in the Pool mode, or the spillover mode, which you won't have unless it has been set up..

Since you have a heater, then you will most likely have to run faster than 1200.. I'd try 1500 to 1800 and see what happens.

If your filter is dirty, the first thing to stop is the spillover..

Show me some pics of your equipment pad, so I can see your Automated Return valve and all the surrounding plumbing.

Thanks,

Jim R.

 

[saggi432]

Sure.. let me get some pictures.. i have been trying 2k in the peak hours between 01:00Pm to 03:30PM every day and it looks good so far..

432,

If things are working the way you want, then I don't need any more pics...

Thanks,
