Zodiac Jandy High Limit Temperature Sensors Kit for JXi 260/400 Heaters – R0592300

Overview

Meet the Zodiac Jandy high limit temperature sensors kit, designed to integrate with JXi 260 and JXi 400 heaters. This kit supports safe, steady operation by monitoring water temperature and guiding the control system to respond to rising heat. Expect a calmer pool experience when temperatures stay within a managed range, even on hot days.

What’s included

• R0592300 high limit sensor module that works with the JXi control system
• Snug, compatible fit for JXi260 and JXi400 models; capable of replacing sensors in select LXI and Legacy heaters
• Two safety switches set at 135 degrees Fahrenheit and 150 degrees Fahrenheit for layered protection

How it works

The dual switches act as guardrails within the heater control loop. When the measured temperature reaches either preset point, the system is prompted to reduce or cut fuel flow, helping to maintain vent clearance and steady operation without abrupt changes.

Real world use cases

• DIY installers can swap worn sensors with common tools, following guidance in your heater manual
• Homeowners with JXi or legacy Jandy units can preserve heater performance with a dedicated high limit sensor kit
