Frequently Asked Questions
Is the 521233 a genuine Pentair part?
Yes. The 521233 is a Pentair part supplied under that manufacturer part number. It is not a generic substitute.
Will this work with my existing control system?
Automation boards and cards are tied to specific platforms and firmware generations and rarely cross between them. Confirm your controller model and firmware revision before ordering.
Can I add automation to an older pool?
Yes, though older equipment may need relays or actuators to be controllable. Single speed pumps and non-communicating heaters can usually be switched but not modulated.
How do I confirm this part fits my equipment?
Check the part number stamped on the component you are replacing, or find it on the parts schematic in your owner’s manual. If the number differs or is unreadable, send us your equipment model and serial number and we will verify fitment before you order.
How quickly does this ship?
In-stock items ship from our US warehouse on business days. You will receive tracking by email once the order leaves the warehouse.
Can I return it if I ordered the wrong part?
Unopened, uninstalled items can be returned within 30 days. Equipment that has been installed or plumbed cannot be returned, so confirm fitment before installation.
Is this covered by a warranty?
Manufacturer warranty terms vary by brand and product. Warranty claims generally require proof of purchase and, on installed equipment, evidence of professional installation.
