Product Overview

The Pentair IntelliTouch® i-Link Home Automation Adapter Interface | 520442 is a genuine Pentair OEM integration device designed to connect an IntelliTouch Pool & Spa Automation System with compatible third-party home automation systems.

The i-Link interface allows supported home automation platforms to communicate directly with the IntelliTouch control system, giving homeowners the ability to integrate pool and spa functions into their existing whole-home control interface.

Compatible automation platforms may include systems from Crestron®, AMX®, Vantage®, Lutron®, Control4® and other compatible third-party automation manufacturers.

Through the home automation system, users can access supported IntelliTouch functions such as activating pumps, controlling valves, operating heaters, switching auxiliary circuits and adjusting temperature settings.

The Pentair 520442 is particularly useful for custom homes, luxury residential projects and professionally integrated automation systems where pool controls need to operate as part of the home's central automation platform.

Specifications

Compatible Home Automation Systems

Pentair designed the i-Link interface for integration with compatible professional home automation platforms, including:

• Crestron®
• AMX®
• Vantage®
• Lutron®
• Control4®
• Elan®
• Other compatible RS-232-based automation systems

Compatibility and available commands depend on the third-party automation system and programming.

What Can the i-Link Control?

When properly integrated and programmed, the Pentair 520442 allows a compatible home automation system to access basic IntelliTouch functions such as:

• Turning pool or spa pumps on and off
• Activating compatible valves
• Turning heaters on or off
• Adjusting thermostat settings
• Operating auxiliary relays
• Controlling supported pool and spa equipment through the home's central automation interface

This allows the pool system to become part of a larger whole-home automation installation.

How the Pentair i-Link Connects

The i-Link acts as a communication bridge between two systems.

Home Automation Controller → RS-232 → Pentair i-Link → RS-485 → IntelliTouch Personality Board

The DB-9S RS-232 connection communicates with the third-party automation controller, while a four-wire communication connection connects the i-Link to the IntelliTouch system.

The RS-485 connection also supplies operating power to the i-Link adapter.

Important Compatibility Information

Pentair 520442 is designed for IntelliTouch automation systems.

This is not a Wi-Fi adapter, ScreenLogic interface or IntelliCenter upgrade kit.

Purchasing the i-Link does not automatically provide smartphone or internet-based pool control. It is intended to allow a compatible third-party home automation controller to communicate with an existing IntelliTouch system.

Before ordering, verify:

• Your pool automation system is Pentair IntelliTouch
• Your home automation controller supports the required integration
• An appropriate RS-232 connection is available
• Your automation integrator supports Pentair IntelliTouch protocol communication
• The installation distance and wiring requirements are appropriate

Professional automation programming may be required.

i-Link vs. ScreenLogic

The Pentair i-Link 520442 and ScreenLogic serve different purposes.

i-Link 520442:
Designed primarily for integrating IntelliTouch with professional third-party home automation platforms.

ScreenLogic:
Designed primarily to provide direct mobile device and computer control of compatible Pentair automation systems.

If the goal is simply to control an IntelliTouch system from a smartphone rather than integrate it with a home automation system, a ScreenLogic solution may be more appropriate.

Installation Guidance

Pentair specifies the i-Link for indoor installation and recommends locating it within approximately 25 feet of the home automation system.

Because correct operation requires low-voltage communication wiring and third-party automation programming, installation should be completed by a qualified pool automation technician or professional home automation integrator.
