Frequently Asked Questions
What does a personality card actually do?
It determines your system's capability — how many auxiliary circuits it can run and whether it handles a pool only, or a pool and spa sharing equipment. The main board provides the processing; the personality card sets the configuration.
What does "i8PS" stand for?
Eight auxiliary circuits, Pool/Spa shared equipment. A single set of equipment serves both bodies of water with automated valve switching.
Can I use this to upgrade a smaller system?
Yes — that's a common use. It converts an i5P system to i8PS configuration, adding circuit capacity without replacing the whole control system.
Will it fit my existing enclosure?
Yes. It's designed for standard IntelliCenter automation enclosures and connects to the i5P main board.
How do I know this is the board I need?
Check the part number printed on your existing personality card, or confirm against your system's parts list. Automation boards are configuration-specific and not interchangeable across personalities.
Does this need professional installation?
Yes. Automation boards involve live high-voltage enclosures and should be installed by a qualified pool technician or licensed electrician.
Frequently asked questions
What can this automation system control?
Pool and spa automation of this type manages pump speeds, heater setpoints, valve actuators, lighting and sanitiser output from a single interface. The exact relay count and the number of supported bodies of water are set by the model and personality kit, listed in the specification section above.
What is the part number for this automation system?
Pentair lists this automation system under part number 521968Z. Quote 521968Z when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
Do I need a professional to install it?
Yes. This equipment is wired into your pool's electrical supply and, in most jurisdictions, must be installed by a licensed electrician or pool professional. Manufacturer warranty coverage on automation equipment commonly depends on professional installation.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Can I add valve actuators, a salt cell or extra relays later?
Most systems of this type are designed to expand, but the ceiling depends on the model and the personality kit installed. Confirm what is in the box on this page before assuming an accessory is included - actuators, transformers and salt cells are frequently sold separately.
Is there a warranty on this automation system?
It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
