My pump currently runs 8am to 8pm. I want to lower the speed and run it 24 hours without significantly altering the chlorine production. I have a Jandy 2.7 hp variable speed epump and use the Jandy PDA to program the pool. It looks like the pump is currently running at 3050 rpm. The PDA settings have an option to program pumps 1,2,3,4? Not sure what this means or how or what to program the pump to. Thanks.
 
Race,

Running at 3050 is way too fast in my opinion... With a heater, you will most likely need to run between 1500 and 1800 rpm to get your cell to turn on..

I personally love running at a low rpm, 24/7... But...

The speed that the pump runs has nothing to do with the amount of chlorine your cell produces.. So, if you wanted, you can continue to run for 12 hours at a low rpm (that still turns on your cell) and the cell will still make the same amount of chlorine it always did.. Or... your can run 24/7 at a low rpm and then you would need to decrease your cell's output by about 50% so that the cell still made the same amount of chlorine...

I have no clue about Jandy products, but would 'assume' that your pump can run 4 speeds.. 1, 2, 3 and 4.. I also assume that you can set the speeds you want and assign them to each number...

Edit... This is what happens when you assume things you know nothing about... :mrgreen:

I 'think' that @PoolGate has a Jandy system...

Maybe one of our Jandy guys can chime in here..

Thanks,

Jim R.

Aqualink will control up to 4 pumps. That is the 1-4. It has nothing to do with speeds. You are using 1. You speed settings should be set to what you want to run. "Pool" speed is the default and should be set to something like 1200-1500 RPMs to satisfy the SWCG.

Don't change any keywords or positions in your speed setup.

What version Aqualink are you using? Is it Aqualink PDA? PDA programming is cumbersome.

Here is the PDA instructions. Page 42 has the menu picture. https://cdn.fluidrausa.com/-/media/...?rev=422546a8eedf442783e378621a908e1e?force=1

I have the Auqalink PDA 6.0, JBOX 4.0, Handheld 3.0. The pool builder programmed the speed and I have never tried to change it. I have a spa that spills into the pool, changing the speed of the pump may change the spill to a dribble? I will have study the Aqualink manual, it is quite complex. If anyone knows specifically where I need to go in the menu let me know. I tried menu/system setup/ Var Speed Pump/Min-Max Settings/Pump 1/Max Limit - changed from 3450 to 2000 and this did nothing.
 
Ok I think I figured it out. menu/system setup/ Var Speed Pump/Speed Labels/Select Pump/Set Speeds/Select Speed Value. I selected High Speed and lowered it to 2000, this seems too slow for the spa spillover. I set it to 2500 and this seems ok, not sure I can go lower. The pump is significantly quieter. If the system pressure doesn't affect chlorine production I may just leave it at the current run time. Thanks for the help!
 
Your spillover should only be active while you are using it. Otherwise these are off as you will increase your pH very high continuously running your spillover. When active, you should have a spillover speed that increases speed to desired setting. For your "Pool" speed a lower speed is better. The cost savings are enormous.

Yes the pH is always high. I have water features that run on a separate pump and can be run independently, but the main pump feeds the pool and spa together so unless I'm missing something there's no way to stop the spillover. The return in the spa is inoperable unless it's in spa mode.

Yes, you are missing something.

Dipswitch 3 enables AUX3 to control your spillover.
