Hayward omnilogic

[jaygrovr]

Does anyone know if its possible to setup more customized alerts on things like PH and ORP if I have sense and dispense? I am running my PH at 7.8 to help with TA, and I am constantly getting high PH messages when it creeps up to 8. It would be lovely to be able to manage these better, and custom.

Thanks
Jason

Sorry you haven't gotten a response...maybe a bump will help...

I have installed quite a few Omni’s but never one with sense and dispense. I do know during the initial setup you can set alerts for low salt warning on the chlorinator. Maybe if you go into config there is something like that for your sense and dispense change your high and low ph warning.

You mean go into the config on the screen? This is one thing that is very frustrating about the hayward system, the onboard screen has a totally different menu structure. The app and screen should all have the same options as the screen never gets used. I would even say to get rid of screen, and is only used once during commissioning.

Yes the main controller

I have one, unfortunately not much can be customized in regards to alerting.
See below what can be configured during initial setup config or if you edit configuration after should take you to same place.

Ok switching topics slightly, I installed my SWG and its running since the salt PPM seemed to be in the correct range. My question is there are two ways to run the SWG in hayward land, one is just percentage mode and the other is monitoring ORP, I do have sense and dispense monitor, but not sure what mode to put it in, and how hard to run it. Being new to this, what is the primary way to tell if its working correctly? Can I still measure free chlorine and chlorine PPM. Any other advise or suggestions? I heard people mention I need to run my pump/filter more hours now to help with the generation? If so, what is normally done there? Thanks in advance.

Use percentage mode. ORP does not work well.

A T325 cell is small for your pool. You will need to run your pump more hours to generate adequate chlorine from the cell.

You can use PoolMath Effects of Adding -> SWG to calculate how much chlorine you will generate with a % and pump runtime.

 

[jaygrovr]

Question on that, pool math is not calculating anything, I am expecting it to return pump run hours, after I enter in all the details, and nothing happens. I am not sure what to enter for Free chlorine either. Nevermind, I figured it out.. Says it can raise by 3ppm in the time period I run my pump. Seems ideal to me. What should be my target?

 

[ajw22]

You enter two out of three - cell type, % or pump runtime and it tells you the other....

I will eventually replace this cell with the larger turbocell. I really like the clear ones, do they work as well as the normal? I can see when buildup occurs. I am also impressed that they reverse the polarity, hopefully that helps with buildup too. I am unsure what target I should be going for with the salt cell, and how to test for that, being so new, I was running liquid chlorine. If anyone can help with that, would be appreciated. I will run pump for 24 hours for the next few days and keep SWG at 80%.

Yes, they work the same.

All cells do polarity reversal.

Every pool is different. you need to dial in your sWG % to where the FC is pretty stable. If your FC is rising every few days then lower the %. If your FC is falling then increase the %. Eventually you will learn what the right % is for your pools environment in different seasons. SWG % is not a set and forget.

Ok so what is my target then for free chlorine?

In LV in the summer it may be 4-5 ppm depending on your CYA level.

 

[jaygrovr]

The daily drop test in my kit with the yellow and red vial is the simple way to check chlorine ppm? should I also be checking CYA often?

The yellow and red vial just tells you if you have chlorine in your pool or not. The chlorine levels are not accurate.

For a numeric reading of your chlorine level you need to use the FAS/DPD test with R-0870/R-0871 reagents.

should I also be checking CYA often?

Check it monthly once you have CYA at the desired level.

Ok I have the tft pro test kit, I can do the correct test. I am just trying to get the swg to be set sorta correctly as it starts to run, so I feel I should be checking the FC at least every few days, to see if its working or not, or if I can turn it down. This is part where I learn how it works and how much it needs to run. Currently my pump only runs 10 hours a day, but I was thinking of running it very low for another 10 hours to help build chlorine.

 

[ajw22]

You have to use the FAS/DPD chlorine test to dial in your SWG.

Both changing the % or pump runtime can be used to adjust chlorine output of a SWG;.

 

[jaygrovr]

So how often should i be testing that based on the installation of the SWG a few days ago? The dial in process? I will test today and post those numbers, and post how often I run with the SWG %, from there I should be able to get it close, I assume.

 

[ajw22]

Go from daily to every other day to every third day as the FC only varies a bit around your target.

If the FC has risen then lower the % a bit.

If the FC has dropped then raise the % a bit.

The FC will never stay perfectly the same for long as the days sunlight time varies so will your FC consumption.
