Feel free to get in touch
The Pentair 521885 iS4 Spa-Side Remote puts four automation functions within arm's reach of the spa. Wired into an IntelliTouch or EasyTouch system with a 100-foot cord, it lets you switch the spa on, run the jets, change lighting and adjust heat without leaving the water — and an LED indicator shows when heating and spa mode are active.

Frequently Asked Questions
Which four functions does it control?
That depends on how your system is programmed. Spa, jets, lights and heat is the usual assignment, but any four circuits your controller supports can be mapped to the buttons.
Is 100 feet enough?
It covers most residential installations. Measure the actual cable route from the spa to the equipment pad, not the straight-line distance, since the run usually follows the deck perimeter.
Is this wireless?
No — the iS4 is a hardwired remote. Pentair offers separate wireless options if a cable run isn't practical.
Will it work with IntelliCenter?
The iS4 is specified for IntelliTouch and EasyTouch. Check your system's parts list before ordering for other controllers.
Can it be retrofitted to an existing spa?
Yes, though running the cable to the equipment pad is the main part of the job — straightforward during a deck renovation, more involved otherwise.
Does this need professional installation?
Yes. It connects into the automation enclosure and should be installed by a qualified pool technician.
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 521885. Quote 521885 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.
