Laars Heating Systems R0015500 Pressure Switch
The Laars Heating Systems R0015500 Pressure Switch is a critical safety component engineered for Zodiac Jandy pool heaters, specifically designed to monitor water flow through the heat exchanger. This adjustable pressure switch operates within a 1-10 PSI range, ensuring the burner only ignites when sufficient hydraulic pressure is detected. It is a direct OEM replacement part for high-performance units, including the Jandy Legacy LRZE and LRZM models, as well as the Laars Lite2 LD, LG, and LJ series. Built with a rugged 1/8" NPT connection and heavy-duty electrical terminals, this switch provides precise water pressure sensing to prevent dry-firing and terminal overheating. For contractors maintaining older Teledyne Laars Series 2 ESG or ESC heaters, this 1-10# pressure switch offers the necessary set-point flexibility to calibrate the system based on the vertical distance between the heater and the pool surface. Proper heater troubleshooting often involves verifying this switch to resolve "no fire" conditions caused by flow fluctuations.
Key Benefits
- Broad Compatibility: Engineered to fit Jandy Legacy and Lite2 heaters, simplifying inventory for service trucks.
- Field Adjustable: The 1-10 PSI adjustment allows for fine-tuning in installations where equipment is located above or below the water line.
- Safety Interlock: Acts as a primary flow safety switch, protecting the heat exchanger from damage due to low water volume.
- Durable Construction: High-tolerance internal diaphragm designed to withstand chemical-treated pool water and thermal cycling.
Common Questions
How do I know if my Laars heater needs a new R0015500 switch?
If your control board displays a "Pressure Switch Open" fault or the heater fails to ignite despite the pump running at full speed, the switch may be failed or out of calibration. Professionals should use a multimeter to check for continuity across the terminals when the pump is engaged.
Can this switch be used in systems with variable speed pumps?
Yes, but the adjustable 1-10 PSI range is critical here. When running variable speed pumps at lower RPMs, you may need to adjust the sensitivity to ensure the heater still recognizes sufficient flow for safe operation.
Is the R0015500 compatible with saltwater systems?
This OEM part is designed to meet standard manufacturer specifications for pool and spa environments, though maintaining proper water chemistry is essential for the longevity of all internal sensors.
