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 619963. Quote 619963 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.
