Jandy R0589701 – 110° Thermal Regulator Valve
Product Overview
The Jandy R0589701 is an OEM thermal regulator valve designed for use with Jandy JXi, JXiQ and ASME pool/spa heaters. It is factory-calibrated to regulate water temperature at 110 °F and helps maintain safe, efficient heater operation by controlling internal flow.
Key Features
- Factory-calibrated to maintain approximately 110 °F water temperature.
- Designed specifically for Jandy JXi, JXiQ and ASME certified heaters.
- Corrosion-resistant construction suited for pool and spa chemical environments.
- Mechanical operation (no electronics) provides reliable performance and long life.
- Restores proper thermal control and reduces risk of heater overheating or short-cycling.
Technical Specifications
- Part Number: R0589701
- Calibration Temperature: ~110 °F (43 °C)
- Application: Jandy JXi / JXiQ / ASME heaters
- Construction: Durable metal alloy designed for heater water system environments
Compatibility & Fitment
This regulator replaces worn or faulty thermal control valves in Jandy JXi, JXiQ and ASME-certified gas heaters. Before ordering, verify the heater model and ensure the existing regulator is the correct part. Installing the correct part helps ensure the heater remains within safe temperature limits.
Installation Instructions
- Turn off heater power and close water supply before servicing.
- Drain or relieve water from the heater body to safe level.
- Remove the old regulator valve from the heater manifold.
- Install the new R0589701 regulator in the proper orientation, following the manufacturer torque and sealant instructions.
- Restore water flow, power up the heater, and monitor temperature operation and heater performance.
Troubleshooting
- Heater short-cycles or shuts off early: Check that the regulator is properly seated and calibrated, and that flow through the heater matches specification.
- Heater outlet water too cool: Verify the regulator is functioning and not stuck open allowing bypass of the heat exchanger.
- Leaks at regulator location: Inspect the sealing surface, ensure correct torque and that the regulator is fully compatible.
Maintenance Tip
Inspect the regulator whenever the heater is serviced. If the thermostat begins to drift or the heater experiences unusual cycling, replacing the thermal regulator can resolve issues before major component failure. Regular inspection and timely replacement help maintain safe and efficient heater operation.
