Laars Heating Systems RE2217700 Limit
The Laars RE2217700 High Limit Switch is a critical safety component designed for precise thermal regulation in hydronic heating systems. Engineered for high-temperature protection, this automatic reset limit triggers at 200° Fahrenheit, breaking the electrical circuit to prevent heat exchanger damage or unsafe operating conditions. As a direct OEM Laars replacement part, it ensures proper calibration and fitment for compatibility with Laars Mighty Therm and Pennant boiler series. This switch features a SPST (Single Pole Single Throw) configuration and is built to withstand the cyclical thermal stresses common in commercial and residential boiler applications. When troubleshooting "limit circuit open" codes, this high limit control provides the reliability required to maintain system uptime. Utilizing a 200F auto-reset limit ensures that once the water temperature drops below the differential threshold, the system resumes normal operation without manual intervention, streamlining maintenance for busy contractors and facility managers.
Key Performance Benefits
- Factory Calibrated 200°F Trip Point: Ensures tight tolerance for high-temperature safety cut-off.
- Automatic Reset Functionality: eliminates unnecessary service calls by restoring the circuit once temperatures normalize.
- Direct OEM Compatibility: Specifically engineered for Laars Heating Systems to maintain UL listing and agency certifications.
- Rugged Sensing Element: Designed for high-cycle longevity in demanding HVACR environments.
- Integrated Mounting Bracket: Simplifies field installation for rapid repairs and minimal downtime.
Common Technical Questions
What causes a Laars high limit switch to trip frequently?
Frequent tripping is often indicative of poor flow rates, a scaling heat exchanger, or a failing primary pump. Ensure your hydronic system flow meets the minimum GPM requirements specified by Laars.
Is the RE2217700 interchangeable with manual reset limits?
No. Safety protocols require using the specific reset type designated by the manufacturer. Replacing an auto-reset high limit with a manual version can disrupt automated system logic.
How do I verify if the RE2217700 is defective?
Using a multimeter, check for continuity across the terminals when the system is cool. If the circuit remains open below the 200°F threshold, the internal contact has likely failed.
