Product Overview

The Pentair Water and Temperature Sensor Kit is a genuine OEM replacement designed for compatible Pentair pool and spa automation systems. This 10k-ohm temperature-sensing system allows the automation controller to monitor water or ambient air temperature so connected heating, cooling, and automated equipment can respond accurately to system conditions. It is an ideal replacement when an existing sensor becomes damaged, inaccurate, corroded, or fails to communicate reliable temperature readings to the control system.

Ideal For

• Pentair IntelliCenter automation systems

• Pentair EasyTouch and IntelliTouch systems

• Pentair SunTouch controllers

• IntelliSync control and monitoring applications

• Compool-to-EasyTouch upgrade systems

• Replacing failed or inaccurate OEM temperature sensors

Key Features

• Genuine Pentair OEM replacement sensor kit

• 10k-ohm temperature-sensor technology

• Suitable for water or air temperature sensing

• Designed for direct connection to compatible Pentair automation controls

• Includes mounting hardware for proper water-sensor installation

• Supports accurate temperature monitoring for automated pool operation

Benefits

Reliable temperature information is essential for automation systems controlling pool heaters, heat pumps, freeze protection, and other temperature-dependent equipment.

A failing sensor can cause incorrect temperature readings, unexpected heater operation, or automation alerts. Replacing the damaged sensor with the correct Pentair OEM component restores the sensing hardware specified for the control system.

Because the same Pentair sensor platform is supported across several automation families, the kit is useful for both current systems and many existing equipment-pad installations.

Compatibility

Pentair identifies this temperature sensor kit for use with IntelliCenter, IntelliTouch, EasyTouch, SunTouch, IntelliSync, and Compool-to-EasyTouch upgrade control systems.

The sensor can be configured for water or air temperature monitoring depending on the control system and installation.

Always verify the existing automation model, sensor function, wiring location, and current sensor configuration before ordering.

Installation & Replacement Context

For water-temperature applications, the sensor mounts in the circulation plumbing and is secured to the pipe using the appropriate clamp. Pentair documentation references installation in compatible 2-inch or 3-inch plumbing.

Installation requires access to the automation control panel and low-voltage sensor terminals. Electrical power to the control system should be disconnected before service, and professional installation is recommended when the system configuration is uncertain.

What's Included

• Pentair OEM temperature sensor assembly

• Sensor mounting clamp/hardware

• Installation documentation

Specifications

Customer Q&A

Can this sensor measure pool water temperature?
Yes. It is designed for water-temperature sensing when installed correctly in compatible circulation plumbing.

Can it also be used as an air-temperature sensor?
Yes. Pentair identifies the sensor for either water or air sensing depending on the automation configuration.

Will it work with IntelliCenter?
Yes. Pentair lists this sensor kit for IntelliCenter as well as EasyTouch, IntelliTouch, SunTouch, IntelliSync, and compatible Compool upgrade systems.

Does this replace the entire automation controller?
No. This is a temperature-sensor kit only. The automation panel, circuit boards, heaters, and other controls are not included.
