Ok, I am not sure if this is across all Intellicenter systems or if it is just mine, but it appears that if there is a power interruption to the control system power, the freeze protection on the AUX circuits turns off.

The feature circuits do not lose the freeze protection, so any circuit in there, stays operating.

Well, I happened to check on the intellicenter this morning while at work, and I noticed that the freeze protection was not on. So I turned the freeze protection back on.

Shortly after I get a call at work from my wife saying the pool equipment was making funny noises. Have her check the pump basket because the web client says 3450 RPM and 0 flow. There is barely any water in it. Tell her to throw the breakers.

I rushed home (8 minutes away) and restarted everything. System started up in pool mode. Everything was fine. Because she had thrown the breakers, the freeze protection was back off. I came inside, and brought up the Intellicenter web client, and selected freeze protection again. Low and behold, about 15 minutes later, I get a no flow alert from my IC40 and the pump is trying to prime again. I killed the breaker and sat there thinking about what could be going wrong. It finally dawned on me that we had a power flash this morning around 6:30. If the freeze protection was turned off then, and I turned it back on about 2 hours later, because the pump lost prime, that the spa suction had to be the issue and is likely freezing/frozen. Got the system started again in pool mode. Got the heat gun and warmed the spa suction pipe up for a while. Reset my suction line actuator so it would always pull a trickle from the spa and pool. This should keep the line from freezing, even if the freeze protection gets turned off again.


TLDR; Check your freeze protection settings often on your Intellicenter as a power interruption seems to turn off the freeze protection to the AUX circuits.

Interesting. Mine just goes from Pool to Spa mode, but I did notice one time that it was only doing spa and not cycling between the 2 bodies. It was barely freezing so I didnt really worry about it, but I checked and the Pool circuit has freeze protection unchecked. I assumed I unchecked the box when I was messing around with the app, but maybe it was due to a power outage resetting it. Something to watch out for and glad you found it.

Jeff, good advice!!! Thanks the info. I've never experienced anything like that but only because I don't mess with freeze protection.
I would let Pentair know about this anomaly.
Very interesting. Thanks again!!
