How to run Pump Speed at Lower RPM than 24/7 Pool Mode?

I have my pool running 24/7 (8am to 8am set up in the ScreenLogic software). However, when I run my chiller at my regular 24/7 Pool RPMs, it is a bit to high of speed, a decent amount of water gets splashed out around the bottom of the chiller and onto the ground. I'd like to program things so I can turn on a "Low Speed" mode for when I run my chiller so I don't lose water, but it seems like the pump won't lower than what I have my 24/7 Pool RPM set at.

Any ideas?
 
Set your 24/7 pool mode rpm to the lower rate you wish. Then set up a Feature with a higher rpm and schedule it for when you want the higher rpm.

What you described seems kinda like the opposite of what I described I'm shooting for.

I want it at the higher RPM 24/7, and once in a while when I use the Chiller, I want it to run at a lower RPM, with a "Low Speed" feature. Is this not possible?
 
N,

The way the EasyTouch works, is that you set the Pool Circuit to the lowest RPM you ever want to run.. Then you use Feature circuits to increase the speed.

When the pump receives two, or more, speed requests, it will always run the fastest one.

Here is my speeds, just to see how it works..

I see. That's kinda dumb of EasyTouch to have zero way to over-ride the "highest RPM wins" rule. I need the RPM's to run Lower than my 24/7 speed, when I run the chiller. It seems lame to have all this nice automation bells & whistles, but not be able to do the most basic thing like easily choose a lower pump speed for something like a chiller every now and then. I run my chiller for 5 minutes or so once a week, even during non HOT seasons, since I'm assuming it's important to run chlorinated water through all my pipes on a consistent basis, no? It would be nice to do this automatically with a schedule, and be able to have a lower pump speed, automatically (per a custom schedule).
 
I would create multiple pump speeds like Jim suggested. A low speed, let’s say, 1200 and a high speed whatever that would be, say, 2000. Set the low speed for 24/7. Set the high speed schedule from 12:05 pm - 11:50 am. For that 15 minutes the high speed is off which only leaves the low speed running and that would chlorinate your chiller pipes.
 
N,

You have two choices.. Whine... or just set it up as designed. I just don't see your point at all.

If you only need to do this once a week, then you can just adjust the speed down by using this ScreenLogic page.. Keep in mind that whatever speed you set it too will stay that way until you change it back. So, if the system is running in the Pool mode at say 1200 RPM, you can adjust Pool down to say 800 RPM.. After your five minutes run, you can set it back to 1200.

I didn't whine, Jim. Poor design, is poor design. Pointing that out, isn't whining. Surprised you chose that tone. Either way, I appreciate your insight.

If I'm understanding this suggestion correctly, it appears to be the OPPOSITE of automation.

Manually adjusting what should be a 5 minute simple automated task during non-hot / non-chiller season, should be easier, and doable with automation. I had it set up to run at 2:30am, before I realized that it's probably not even doing my Low Speed setting. It's silly that I'll just have to splash water out of the chiller just to run the darn thing, all because the Automation doesn't let me run the pump at the lower RPM I want it to run at. for 5 minutes at 2:30am. It's certainly a lacking feature of the software to never be able to Lower the pump RPM (in a 24/7 Pool mode scenario) for unique or necessary reasons... and it would be a SIMPLE fix. And no, that's not whining, it's just a fact.

Thanks for this suggestion. I didn't get this idea from anything Jim posted, so thank you for explaining it the way you did. Jim suggested that I just adjust to the LOW RPM speed manually, and NOT use automation for when I want my Chiller to run in an automated weekly pattern. What you suggested actually seems like a way to get around it, using automation, and not having to remember to turn my Low Speed RPM on, then the chiller, then turn the chiller off, then turn the RPM back up, every single week.

What you suggested also shows how silly the software is, to have to back your way into 15minutes of Low RPM once a week (in your expample) in this fashion. It's just poor design, and no, that's not Whining, just a fact.

I see you have a Glacier Chiller as well..... do you also run it every so often in non-Chiller season, to make sure those pipes have chlorine? If so, how often and how long? I'm kinda new to the chiller world.
 
Until I saw your post and question, I never thought about running my chiller in the off season to chlorinate the chiller's return. When I shut it down for the off-season, I closed the chiller inlet valve. I opened the drain valve (ball) and then rinsed the chiller out with the hose. The chiller bowl emptied through the drain valve then I walked away.

Fortunately, for me, the way the plumbers plumbed it, I don't think it will be much of a concern. The chiller outlet is plumbed to the pool's return header. There is a check valve on the chiller outlet pipe. That pipe run might be 5 feet, if that. No biggie. I guess I'll find out when I crank it up in a couple of months.

It just seems unfortunate that if I want to use basic, simple automation, I have to lose/waste water, every time the chiller runs, since at my normal pool RPM's, it splashes water on the ground around the chiller.

There actually is only the Pump if you look at Jim's screenshot. The Pump has 8 circuits for scheduling, each named what you choose. That's all the automation anything can have, since the Pump can only do one thing at the time. My fast pool circulation is on a circuit named as such, by me, and the my slow pool circulation is on the circuit named pool, which I believe Pentair reserves Circuit 1 for.
 
Nik,

I have been thinking about your chiller issue and have an option that might work for you..

Just some quick background so that we are all on the same page. The SWCG will only work if the Pump/Filter relay is closed. This relay will only close if the system is in either the Pool mode or Spa mode. Normally, to run 24/7, you would set the Pool Circuit to be on 24/7, which would close the Pump/Filter relay 24/7. By system design, this means that the pump can never run slower than the speed set for the Pool Circuit.

The pump knows what speed to run based on which Circuit, or Circuits, are "On". To make the pump run faster, you have to use Feature Circuits and assign speeds to them. If you look at the screenshot below, you can see where my Pool Circuit is assigned a speed of 1250 RPM. I also have three Feature Circuits... Skim Low which runs the pump at 1500, Skim High which runs the pump at 2000, and Waterfall which runs the pump at 2800. I can make the pump run faster or slower by turning these Feature Circuit on or off. But, I can never make the pump run below 1250 because the Pool Circuit is scheduled to be on 24/7.

One option would be to set up your Pool Circuit for say 500 RPM (as an example). Schedule the Pool to be on for 24/7. Then set up a Feature Circuit and name it "Pool Fast" (You can name it anything you want..) Schedule Pool Fast to run 24/7 at say 1500 (or whatever speed you are running now). Since both circuits are scheduled to run 24/7 then the pump will never run at 500 RPM unless you shut off Pool Fast. You can do that manually or with a schedule.

Again, not sure that is what you want to do, but it seems that what you want to do can be done a couple different ways. Tell me how you wish your system to work and I'll see if I can come up with an option that will work for you.
