Pentair 520272 Temperature Sensor with 20ft Cable – Replacement Part for Pool & Spa Automation

Overview

The Pentair 520272 Air/Water/Solar Temperature Sensor is a genuine OEM replacement part designed to integrate with pool and spa automation systems. With a 20-foot cable, it enables flexible placement to capture ambient air, pool water temperature, or solar panel heat, helping your automation controller respond to real conditions.

What it does

As a temperature sensing node, it feeds data to compatible Pentair control units so you can monitor temperatures in real time, set schedules, and optimize system performance. While outcomes can vary, accurate readings often lead to more responsive automation and smoother control when the sensor sits where it belongs.

Key benefits

• Genuine OEM Pentair replacement part ensures compatibility and reliability.
• 20-foot cable offers flexible installation options for pools, spas, or equipment rooms.
• Supports air, water, and solar temperature sensing for multi point monitoring.
• Designed for pool and spa automation systems and pump controllers to help informed control decisions.

Usage scenarios

In a sunny backyard, place the sensor near the pool edge to track water and ambient air temperatures for smarter heating and circulation. In a spa setup, position the sensor to monitor water temperature for consistent comfort. For solar assisted heating, the sensor helps regulate flow based on panel temperature readings.
