Product Overview
The Pentair TS5L Linear Temperature Sensor is a genuine OEM replacement sensor designed for compatible Pentair ComPool® and LX80 pool and spa automation systems. It provides temperature information to the control system for applications such as water-temperature monitoring, solar control, and supported freeze-protection functions.
Pentair identifies TS5L specifically as the linear temperature sensor with red and green wires for ComPool systems and the LX80 / CP3000 family.

Compatibility
The TS5L is intended for compatible:
- Pentair ComPool® Control Systems
- Pentair LX80 Commercial Pool & Spa Control Systems
- CP3000 family of products
- Compatible ComPool water-temperature sensor applications
- Compatible ComPool solar-temperature sensor applications
Pentair's current parts catalog continues to list TS5L as the ComPool linear temperature sensor with red and green wires.
Important Compatibility Note
The TS5L is a linear sensor and should not automatically be substituted for Pentair's newer 10K thermistor sensors, such as 520272.
Pentair lists TS5L and 520272 separately because they are different sensor types intended for different control platforms.
Water Temperature Sensor Application
For compatible ComPool systems, the TS5L can be installed in the pool circulation plumbing to measure water temperature.
Pentair's CP3000 documentation specifies positioning the TS5L between the pump and filter. The sensor is inserted through a 5/16-inch hole in the plumbing and secured with a sensor clamp.
Accurate water-temperature readings allow the automation system to manage compatible functions such as:
- Pool heating
- Spa heating
- Temperature display
- Automated temperature control
- Related programmed equipment functions
Solar Temperature Applications
The TS5L is also identified for compatible solar-temperature sensing applications.
When properly connected to a compatible ComPool solar-control system, the sensor allows the controller to compare temperatures and determine when solar heating should operate.
Red & Green Wire Configuration
One of the easiest ways to identify the TS5L is its red and green wiring.
Pentair's CP3000 installation documentation instructs installers to maintain the color-coded connections:
Green → Green
Red → Red
Waterproof connections should be used when extending or joining the sensor wiring.

Pentair lists these components together within its automation temperature-sensor replacement parts.
When Should the Sensor Be Replaced?
Consider replacing the TS5L when the automation system experiences:
- Incorrect water-temperature readings
- Temperature readings that do not change
- Erratic temperature display
- Solar system failing to respond correctly to temperature
- Damaged sensor wiring
- Corrosion at electrical connections
- Physical damage to the sensor probe
- Existing TS5L sensor failure
Before replacing the sensor, inspect the wiring and connection points since damaged wiring can also produce incorrect readings.
Installation Information
For compatible water-temperature applications, Pentair's CP3000 instructions specify:
- Turn off pool equipment.
- Select a location between the pump and filter.
- Drill the specified 5/16" hole.
- Insert the temperature sensor.
- Position the appropriate sensor clamp over the sensor.
- Tighten gently to create a watertight seal.
- Connect the red and green wires to their corresponding wiring.
- Restore power and verify temperature operation.
Pentair cautions against overtightening the clamp because excessive force can deform the sensor O-ring.
Frequently Asked Questions
What is Pentair TS5L?
TS5L is Pentair's linear temperature sensor with red and green wires for compatible ComPool automation systems.
Does TS5L work with LX80?
Yes. Pentair identifies TS5L for the LX80 control system / CP3000 family.
Can it measure pool-water temperature?
Yes. TS5L can be used as a compatible water-temperature sensor.
Can it be used for solar temperature?
Yes. Pentair identifies TS5L for compatible solar and water temperature sensing applications.
What color wires does it have?
Red and green.
Does wire polarity matter?
For the original ComPool TS5L installation, follow Pentair's specified color matching: red-to-red and green-to-green.
Is TS5L the same as Pentair 520272?
No. TS5L is a linear sensor, while 520272 is listed separately as a 10K temperature sensor for other Pentair automation platforms.
Is the mounting clamp included?
Do not assume it is included. Pentair lists 9321004 sensor clamp and 9142109 sensor O-ring as separate service components.
