Water Temperature Sensor ECS0275 for STK0127 Heater Erchon

Description

Product Overview

The ECS0275 water temperature sensor is a precision component engineered by Erchon for use with the AquaCal STK0127 pool heater heat pump. Built around a high‑quality 10K thermistor, the sensor delivers consistent resistance values from -58 °F to 230 °F, ensuring the heater’s control board receives accurate temperature data. Its compact dimensions (1 × 1 × 1 in) and lightweight design (2.64 oz) make it easy to handle while its robust housing protects against corrosion, UV exposure, and the chemical environment typical of swimming pools. The sensor replaces part number STK0127 and integrates seamlessly with the existing wiring harness, eliminating the need for additional adapters or modifications.

Usage

This temperature sensor is intended for residential and light‑commercial swimming pools equipped with AquaCal heat pump systems. It monitors water temperature continuously, allowing the heater to maintain a setpoint that keeps the pool comfortable for swimmers while optimizing energy consumption. Installation is performed by disconnecting power, removing the old sensor, and mounting the new ECS0275 in the same location using the supplied bracket. The sensor’s quick‑connect terminals align with the heater’s wiring, making the replacement process achievable in under 15 minutes for most DIY enthusiasts. It is also suitable for spa applications that share the same heater model, providing reliable temperature feedback in both indoor and outdoor settings.

FAQ

Is the ECS0275 compatible with all AquaCal heat pumps?

The sensor is specifically calibrated for the AquaCal STK0127 model. It will work with any heater that uses the same part number, but compatibility with other models should be verified against the heater’s specifications.

Do I need any special tools to install the sensor?

No special tools are required. A standard screwdriver to remove the mounting bracket and the supplied wiring connectors are sufficient for a quick replacement.

How does the 10K thermistor improve temperature control?

The 10K thermistor provides a stable and linear resistance change across the operating temperature range, allowing the heater’s controller to interpret temperature data more accurately and maintain the desired setpoint with less fluctuation.

What is the warranty coverage for this sensor?

Erchon offers a one‑year limited warranty covering defects in materials and workmanship. If the sensor fails within this period, a replacement will be provided after verification of the issue.

Can this sensor be used in a spa environment?

Yes, the ECS0275 can be installed in spas that use the same AquaCal STK0127 heater, provided the mounting location meets the sensor’s immersion depth requirements.
