Thanks for this info, James. I don't believe there is a way to run my pump in RPM mode under my i9 automation system, but this could be handy for testing.

Oh yeah, this is an obsolete model 011012 from Mar2011. I was searching the manual for an RPM mode, but I don't see anything.

I have had this VF pump for a long time and am very familiar with specs it reports at various settings. In my setup, at a 35 GPM setting, the power consumption is always around 490-ish with a clean filter. As the filter gets dirty, the consumption will increase to maintain the flowrate...

Thanks for the response, Jim. In this case, the observed flowrate at the returns was reduced because the pump motor was barely running, ~140 watts instead of 475-500. Also, I did a complete filter service only 2 months ago. As this is a variable flow pump, I'm not aware of an option to run...

My variable flow pump seems to be incorrectly reporting the flowrate in ScreenLogic after a few minutes of operation. When I first start the pump, it shows a normal ~450-500 watts, 35 GPM and the spa fountain and tanning ledge returns are bubbling normally. However, after a few minutes, the...

Well, I finally resolved my IC40 Chlorinator communication issue! I debated between rolling the dice on a new IC40 (now 8 years old, but still functioning just fine with the IC40 panel controls) or a replacement Surge card. The Surge card was the cheaper guess/attempt, though I felt a less...

Do you think the #521593 is a drop-in replacement for my #521091?

Thanks Jim. I'm out of warranty. This system has been working together for about 8 years. I'm considering trying to replace the surge card, but I'm not sure what I need. Mine is #521091 and looks quite a bit more complex than the surge cards I see available. Will the #521593 or #521218...

I was skeptical when Pentair tech support suggested replacing the IC-40 flow sensor since the unit seems to function properly in a stand-alone mode (detecting flow, measuring salinity, and producing chlorine), but I went ahead and replaced the flow sensor anyway. No improvement - the IC-40...

Well, as I said, it surely makes sense to me that the output percentage be taken into consideration to calculate Cell hours, but the Pentair "expert" said I had that wrong. I asked twice to ensure there was no misunderstanding. Sounds like they may have given me bad info.

I called Pentair. First I spoke with an Automation guy, who had me move Comm connections around to troubleshoot the cable. I had already done this over the weekend, and also done continuity tests across all the Comm terminals. Comm ports seem fine. Next, I spoke with an IntelliChlor person...

HI Jim, Yes, the IC-40 is enabled on the Screenlogic configuration. The IC-40 is about 7 years old. I take it inside every year when not in use. My surge card (how does it get that name?) wiring doesn't look disturbed. I am the only one who's been inside the load center since installation. I...

Jim, Thank for the responses. Yes, I have an IntelliFlo Variable Flow. It says Display Not Active, as expected, since IntelliTouch is in the normal "auto" mode, not "service" or "time out." Everything else about the installation is working normally. This system is about 7 years old. Also, I...

No, sorry, I forgot to mention that. I tried various setting on Screenlogic, such as different chlorination percentages and super-chlorination. The IC-40 does not respond and Screenlogic eventually resets to showing 0%.

Issue IntelliChlor IC-40 is working properly, but ScreenLogic 2 is reporting “Chlorinator: Communication Lost.” Equipment: All Pentair, except Polaris 280 + Booster IC-40 FNS Plus 60 sq ft DE filter Master Temp 400K i9+3 automation system IntelliFlo variable Flow pump Approx 15K gallons...

Yes, I have a Pool/Spa combo. (Note I'm not the OP, but I thought this was an on topic question.) Do you think if I assigned the Freeze Circuit, it would override the Pool/Spa RPMs when they turned "on with freeze"?

Moved from here.. ScreenLogic help please Jim - under what scenario would one use the "Freeze" circuit under the "IntelliFlo (step 4 of 5)" configuration page? In a pool/spa combo, if "on with freeze" is selected for both the pool and spa circuits on the step 2 page, then these circuits would...

I have been supporting for several years with test chemical purchases, but I will look at stepping it up a bit. You guys saved me a lot on this one, so it's fair that I apply some of that.

Never mind about the heater. That "128 r13" isn't an error code, but some kind of version info, such as software or firmware. I simply had to wait a bit longer, then hit the pool or spa switch, and the heater fired up. (I had tried the manual buttons earlier, but I guess didn't wait long...

Thanks Tom. I installed one of the other ICs in U13 and the relay is behaving as expected! However, the heater is not. When the i9 powers up, the heater is no longer coming on immediately (as expected), but when the i9 calls for the heater, here is what happens: the heater shows lights for...

I didn't see a reference to a source or part number for the driver chips. Do you have that? These socketed driver chips must be on the main board and visible after removing the upper board, right? My protocol adapter was hardwired. I have had so many issues with those over the past 8 years...

Jim, With power off, and heater disconnected from J30, I have an open circuit. With power on, but no equipment running and no heater demand, I have a closed circuit. Based on the discussion in the other thread, I was expecting (a failed) relay driver to always have the relay either closed or...

Thanks for the thread reference! That sounds like almost my same scenario! Sorry, I usually do a better job of searching. I thought this was going to be a fairly unique scenario, silly me. I haven't checked the Intellibrite lights yet - I will do that this evening. But I also lost the...

Issue Heater is running in manual mode following power surge and storms/lightening in the area. I believe I had a power surge that may have damaged either my heater control board or i9 control board. Stuck my hand in the pool and was surprised it was 90 F. Checked automation system and heater...

Hi guys. I just wanted to report that my pump has been running normally for weeks now; no more random restarts. I'm guessing the issue had something to do with adding 2 bags of salt through the skimmer (which I know now not to do anymore). This may have caused an unusual or erratic flow rate...

Gary, I took a closer look in my Load Center, and the pump motor is definitely wired directly into a relay - the red and black from the motor go to Line 1 and Line 2 of the Aux 2 relay. However, this relay is daisy chained to Line 1/2 of the Filter Pump relay, then Line 1/2 of the Filter Pump...

I called Pentair. The Tech was stumped. The Tech said it is probably either the drive unit (drive controller I think would be a better name for this), or the Intellitouch board. Failing Intellitouch boards have apparently been known to "ghost" - or randomly turn stuff on and off. I doubt...

I do not have SVRS. I have the VF pump, model #011012. It does not come in SVRS. Regarding the salt in the skimmer, I don't think this is causing the random restart problems, because days after adding salt, it is still doing the random restarts. However, I guess I should stop adding salt to...
