Resideo L4006E1000 Aquastat
The Resideo L4006E1000 Aquastat is a high-performance, immersion-type controller designed for critical high-limit protection in hydronic heating systems and storage tanks. This industrial-grade aquastat control features a manual reset mechanism, ensuring that once the high-limit temperature is reached, the system requires professional inspection before resuming operation. It operates on a 130-270°F temperature range, utilizing SPST switching where the contacts break on temperature rise. Engineered for versatile field application, it supports both horizontal and vertical insertion of the sensing element, making it compatible with most existing immersion wells. The Micro Switch snap-acting technology provides precise, reliable activation, eliminating the risk of arcing in high-demand boiler applications. For contractors, the visible control scale and external adjustment screw simplify the setpoint calibration process during installation or maintenance cycles.
Key Benefits
- Mechanical Precision: Features SPST switching that breaks the circuit at the user-defined high limit to prevent system overheating.
- Broad Operating Range: Covers a 130-270°F scale, suitable for domestic hot water and commercial hydronic high-limit safety.
- Flexible Installation: Universal mounting allows for horizontal or vertical insertion, reducing the need for multiple SKUs on the service truck.
- Durable Sensing Element: Includes a 3/8-inch x 2-7/8-inch copper bulb for rapid thermal response and long-term reliability in liquid immersion applications.
- Safety Compliance: UL-rated as a limit device, providing necessary boiler safety control for modern HVACR standards.
Common Questions
Does this model automatically restart?
No, the L4006E1000 is a manual reset model. If the temperature exceeds the setpoint, the internal snap-acting switch breaks the circuit and must be manually depressed to restore power once the temperature drops below the high-limit threshold.
What is the maximum pressure rating for the immersion well?
Standard Resideo immersion wells for this series are typically rated for 255 psi, ensuring they handle the pressure fluctuations of most residential and commercial hydronic systems.
Can this be used for circulator control?
While the L4006 series can be used for various tasks, this specific "E" model is primarily utilized as a high-limit controller because it breaks the circuit on temperature rise and requires a manual reset, which is generally not ideal for standard circulator cycling.
