Trying to set up my Jandy ePump speeds

[jonathanfmills]

I bought a house in November and just opened the pool and have not had one before. The previous owner's settings are no longer available so I am attempting to set up the epump speeds myself. My pump is a jandy epump vsfhp165qut and the heater is a jandy jxi260n. I think I have 2 inch pipes with 3 incoming and 2 returns. Images are included.

Everything is controlled through iAquaLink so need to figure out what speeds to program for when heater is on vs not on.

~23000 gallon 40x20 salt water pool.

Any help is very much appreciated

23k gal IG vinal salt water pool, Jandy VSFloPro pump, JXi Heater, Sand Filter, IAquaLink automation, Test with a combination of TF-Pro Salt and Leslie's..

Did you set up these speeds?
Do you have a spa that is attached to the pool?

Also, show us the screenshot of your SCHEDULE for the pump.

I did not set them, it came like this or was set previously somehow. The schedule is empty, nothing there. That is ultimately where I want to get, is what would I put into the schedule.

It is just the pool and a water slide and no elevation change between the pool and the pump. No spa or other water features

You simply go the menu and select Schedule (top left). then Hit Add. You want to select “Filter Pump” then set time for on and off and which days. The pump will run whichever speed is set to Pool - per your setting that is 2750 rpm. You can then schedule other speeds, lights, etc.
I think 2750 rpm is too high for just normal daily running of your pump. You want your most used pump speed to be the lowest speed that activates the flow switch on the SWCG. So reset the Pool speed to 1800rpm and see if that still activates the SWCG. Do NOT change the label that states POOL. The firmware go to label 1 for the Filter Pump schedule. You have to go into VSP setup to change the speeds for any label.

I am not a fan of setting labels such as 2250 or 3000, I would rather say Slow Spd or Med Spd, etc.
Also I would suggest you rename Label 5 (currently 2150) to “Pool Heat”. Then put that RPM at 2500 to start.

Thank you!

How can I be sure that 2500 will be sufficient flow for the heater? Or am I over thinking that.

My goal would be to run at high speeds only long enough for one turnover and then lower after that, I can get the schedule down from there but my main concern is knowing what speed I should be running for daily clean, heater, and the rest of the time. Is there meaningful difference between 1800 and 2000, etc?

Turnover is meaningless...

What are you looking to accomplish in that highs speed run?

daily clean,

What cleaner?

Every pool is different. Experiment with different speeds and run times and see what works for you.

heater,

2100 - 2400 rpm usually works for good flow through the heater.

Run the heater and put your hand around the output PVC pipe connected to the heater. If it is barely warm and not hot then your flow is fine.

and the rest of the time. Is there meaningful difference between 1800 and 2000, etc?

200 RPM above where your SWG flow switch turns on.

Excellent, Thank You!

@jonathanfmills
The main reason to have a VS pump is to run it at the lowest speed for a given function. The activiation of the SWCG flow switch is normally that what sets the lowest operating RPM. You want your pump set at 200rpm above this minimum speed to activate the SWCG, as this accounts for dirty filter, etc that will reduce flow rate over time
Next is skimming. Most pools have some skimming even at the lowest speed set for the SWCG. As a minimum, it is still circulating water. Suggest that you increase speed for 1-2 hrs a day to have a high skimming effect if you have lots of debris entering your pool.
A heater requires even a higher flow rate - usually 2400rpm or above.
If you have water features then those may also require higher RPM.
A suction side vacuum will also require higher RPM. Try to limit that to just what is needed and do not run it if not needed.

See the photo below which is energy usage vs speed. This is my pump but is representative of most VS pumps.
Going from 1500 rpm to 2000 rpm only increases energy consumption by 250
But going from 2000 rpm to 2500 rpm increases energy consumption by 500.
As you can see this is not a linear scale. So the goal is to run at the lowest speed needed to accomplish a given task.
Hope this puts it in perspective
