Pentair Intellicenter I5PS - Constant Issues

[AV8RG8R]

I have an 8 month old I5PS system, running a pool/spa combo in Florida. I have a 3hp Intelliflo VSF, and an Ultratemp 140 heater. I have had numerous electrical/computer gremlins plaguing this system, dating back ~2 months. First instance, we had a power outage, and when system restarted, the Heater was disassociated from the spa - couldn't turn it on. Took me half of a BBQ to figure out what had happened, and why, and to go into the configuration and reinstall it. Things like this have appeared regularly, since. Today, a new one: the heater bypass actuators (521485), all of a sudden blinking auto/off, and not rotating to Heater mode, in Spa mode. They can be rotated manually in service mode, and oddly, they still rotate under automation to the correct positions when selecting Pool Heat. I've reset the system a few times, and nothing has resolved on this bogey.

Has anybody had any similar experiences? Pentair has opened a service case based on prior complaint, and disappointingly, nobody has heard of these types of issues.

Did you have these problems when running on 1.064?

I have had this occur once also after a power outage. In my case it took a reboot of the ic then cycling the intellivalve thru the modes back to auto.
This however also is what happens when they begin to fail from water intrusion. Is this valve by any chance installed face up?

I have a 3hp Intelliflo VSF,

Is this a 011056 pump? If so, Check the firmware revision on this as well. Based on your build time you could have one of the problematic firmawares. If 3.03/3.04, it needs to be updated and will cause gremlins until done. To see this you will need to put the intellicenter in service mode then go into the pump settings to check firmware.

Update: Pentair came out, downgraded the firmware to an earlier one that had fewer known bugs. It has been a little bit more stable since, but I'm still having issues with the valve actuators. They go into freak-out-mode after every periodic power flicker/outage, which is frequent here in FL.
