Description
Product Overview
The 009577F Temperature Sensor is engineered by Flngr to meet the exact specifications of a broad spectrum of pool heater models. Constructed from high‑temperature resistant alloys and precision‑molded thermistor elements, the sensor delivers consistent and accurate temperature readings across the full operating range of residential and commercial heating systems. Its compact 10 × 1 × 1 inch form factor and lightweight 1.45 oz design allow for seamless integration into existing heater housings without the need for additional brackets or modifications. The sensor operates on a 3‑wire NTC 100 K configuration, providing reliable feedback to the heater’s control board, which in turn regulates fuel flow and burner activity to maintain the desired water temperature. Compatibility extends to models 206A, 207A, 266A, 267A, 336A, 337A, 406A, and 407A, making it a versatile solution for pool owners seeking a single part that covers multiple product lines. ![[Product front view showing all components]](https://www.prismstore.store/wp-content/uploads/2026/07/61f41a2b654b4971b55d3a9e5e4a8fe3.jpg)
Usage
This temperature sensor is intended for use in outdoor pool heating installations, hot tubs, and spa systems where precise temperature control is essential for comfort, safety, and energy efficiency. It is suitable for both new installations and retrofit projects, allowing technicians to replace faulty or aging sensors without disassembling the entire heater assembly. The sensor performs optimally in environments ranging from temperate climates to extreme heat, thanks to its robust construction and resistance to corrosion caused by chlorine and other pool chemicals. Homeowners can install the sensor themselves using basic hand tools, while professional service technicians will appreciate the plug‑in design that reduces labor time and eliminates the need for soldering or complex wiring. The sensor is also ideal for seasonal maintenance cycles, where quick replacement ensures the heater returns to service promptly after winter shutdowns.
