Pentair VS Pump not communicating with Intellicenter

I have a 356928.C Pentair VS IntelliFlo Pump that is approximately 3.5 years old. Never had a problem with it. It’s connected to an IntelliCenter.

I updated the Pentair iPhone app weeks ago and all was working fine. For the first time since updating the app we wanted to use the spa. I turned off the pool pump and turned on the spa and heat with the app. About 10 minutes later I noticed the the spa was draining! Almost all the water was out of it. I turned off the hot tub in the app, and the spa filled back up.

I tried to turn the pool filter back on, but the IntelliCenter was not communicating with the VS IntelliFlo Pump.

1) I did get an error code on the VS pump screen f90052.

2) The VS IntelliFlo Pump works manually. I had to do a reset after the error code, but I can now turn the pump on manually in the IntelliCenter service mode.

3) I reset all the breakers on the IntelliCenter panel. The panel also has the newest firmware installed.

4) There is an error code in the IntelliCenter panel Communication Lost: IntelliCenter panel is unable to communicate with the IntelliFlo Pump

5) I checked all connections from the pump to the IntelliCenter. All look stable and good.

I’m at a loss as to how to proceed. I was thinking it could the the IntelliFlo Pump Drive Assembly, but why would it work manually at the pump if the assembly is faulting?

Not sure where to go from here… Any help would be greatly appreciated.
 
I just had the pump filter going manually. So I turned it off and switched to AUTO mode. The display showed the error f90052 ALARM! power out/off. Now there is nothing on the display.
 
Jasf,

Does your pump get constant AC power, (as it should) or is it wired into the Load side of the Pump/Filter relay? (Which it should not be...)

As a test, put the system into the Service mode, wait one or two minutes and then see if your pump's display is blank.. If blank, most likely your pump is wired wrong.

Thanks,

Jim R.

JASF,

That is not what I said to do... Go into the Service mode and do not touch the "F" (pump/filter) button.. Tell me what happens after a minute or so..

If the display is blank, and when you push the "F" button, the pump comes on, then that proves your pump is not wired correctly..

Thanks,

Jim R.
 
JASF,

When the pump is wired to the load side of the Pump/Filter relay, and you are not in the Pool or Spa modes, the relay opens and shuts off the pump. Even with no AC power, the pump works for a second or so.. it thinks that there has been a Loss of AC power and reports a fault.. Depending on the timing, it will sometimes report the fault, and sometimes not..

The whole point of the Service mode is that it shuts off the automatic control of the pump and switches it over the pump's control panel.. I have three pools that all have EasyTouch systems and IntelliFlo pumps.. I have never once had to manually push the 'F' button...

Most likely, you can just move the two hot wires going to the IntelliFlo from the Load side of the P/F relay to the Line side of the relay..

Thanks,

Jim R.
 
Thank you... I've attached pictures of the wiring. I'm to move the two white wires to the left and secure with the other wires one with the (orange/red) & one with the (black).
There should be no wires on the load side of the relay.

JASF,

Ok.. You have two transformers, so I just assumed... :( Do you have any kind of salt cell??

Do the two white wires on the Pump/Filter relay, pins 2 and 4 go to the IntelliFlo?

If they do, you can either move them over to the line side, where you would have 3 wires on pin 1 and 3 wires on pin 3.. or you could just use wire-nuts to connect the 3 wires together.

Thanks,

Jim R.

Jim,

Yes the two white wires go to the IntelliFlo.

I do not have a salt cell.

I'm not sure what the transformers are?

I'm attaching a pic of our set up. There are two pumps that I believe are used to drain water from the pool and spa. There is the blower for the spa, the pump filter, and a booster pump, plus the heater.

So it's ok to move the 2 white wires as you stated above?? They were wired wrong?

Thank you!

I rewired the IntelliFlo as you suggested …. I have no error codes at the Pump or the IntelliCenter. But the IntelliCenter is still not able to control the pump. I will check if the lights work later once it gets darker. In the meantime I have our local pool guy coming tomorrow morning to check it out. I feel I‘m armed with a little more knowledge so hopefully I don’t get scammed.

Thank you!
 
JASF,

Your automation system needs several things to happen before the pump will run...

The system has to be in AUTO..

The system must have at least one Circuit Scheduled to be on.. (Normally the Pool or Spa circuit, but does not have to be..)

The Circuit that is on has to have a speed assigned to it. (Example Pool Circuit = 1500 RPM.. )

The Pump Type should match the actual pump type VS or VF or VSF, etc... (If you change the pump type, it will erase all your current speeds...)

The RS-485 cable needs to be connected to the pump.

The pump's display should show that the system is being controlled by the automation.. (Usually, the pump's display will show "Display not Active.."

Thanks,

Jim R.

Thank you… I’m not sure I understand all what you said. But I will investigate. My husband says…. I never give up. :).

Jim,

I want to thank you for all your help! This morning I followed your instructions above and as soon as I assigned a speed to the pool circuit the pump started up. All works as it should, all components are communting. I canceled the Pool Service Tech! :) Thanks again!!!
