Did you originally upgrade from an EasyTouch or IntelliTouch to the IntelliCenter?
If you did, then you should of used one of the applicable upgrade kits.
However, an upgrade CAN be accomplished by purchasing the necessary parts a-la-carte. I did that because when I upgraded an IntelliTouch Load Center to an IntelliCenter, there were no bundled upgrade kits available.
If you did not use one of the bundled upgrade kits and only upgraded the OCP circuit board w/faceplate (523050) without also upgrading the System Transformer (522102Z), which also includes the upgraded low-voltage circuit breaker harness, then that might be where the problem is.
To summarize. When someone upgrades an *Touch system to IntelliCenter and attempts it without purchasing one of the applicable bundled upgrade kits, they not only have to purchase and install the OCP Circuit Board but also purchase the IntelliCenter system transformer and low voltage circuit breaker harness and then remove and replace the old system transformer and low voltage circuit breaker harness with the new one.
Agree with
@mknauss with regards to an IntelliCenter OCP circuit board (mother card) on ebay $150.00. Something is most likely wrong with that picture.
Also please note that many of the Pentair parts (to include the IntelliCenter upgrade kits) are not available at this time.
Thanks...
