Resideo L4006E1125 Aquastat Controller
The Resideo L4006E1125 is a professional-grade high limit aquastat designed for precise hydronic heating system control and safety. This immersion-style aquastat controller features a fixed 3-inch capillary and a 3/8" x 2 7/8" copper bulb, providing rapid thermal response for boiler temperature regulation in commercial and residential storage tanks. Engineered with SPST contacts that break on temperature rise, this unit serves as a critical fail-safe by interrupting the burner circuit when temperatures reach the user-defined setpoint between 100°F and 200°F. The manual reset functionality ensures that any over-temperature condition is physically addressed by a technician before the system resumes operation. Its flexible design supports both horizontal and vertical mounting, making it a versatile replacement aquastat for various field configurations. With a robust Micro Switch snap-acting mechanism and a visible control scale, this controller provides the reliability required by veteran HVAC contractors for high-stakes limit control applications.
- Enhanced System Safety: Features a trip-free manual reset button that prevents automatic restarts after a high-limit event.
- Broad Compatibility: The 100°F to 200°F operating range is ideal for secondary limit protection in diverse hydronic systems.
- Rugged Construction: Utilizing a copper sensing bulb and liquid-filled element for long-term consistency in high-pressure environments.
- Field Versatility: Supports multiple mounting orientations and accommodates direct immersion or well-based installations.
Common Questions
Does this unit come with an immersion well?
No, this model is designed for use in existing wells or direct immersion; a specific well is not included in the package.
Can the L4006E1125 be used as a circulator controller?
This specific model is a high limit controller with manual reset. For circulator applications requiring automatic reset or "make on rise" switching, an L4006A or L4006B would be the appropriate selection.
What are the electrical load ratings for the contacts?
The SPST switch is rated for 8A at 120V AC and 5.1A at 240V AC for full load applications.
