Resideo L4006E1042 Aquastat Controller
The Resideo L4006E1042 Aquastat Controller is a professional-grade high limit aquastat engineered for precision temperature regulation in hydronic systems, including boilers and storage tanks. This immersion-type device features a manual reset mechanism, ensuring system safety by requiring a physical intervention if temperatures exceed the designated setpoint. Designed with a 130°F to 270°F operating range, it utilizes SPST contacts that break on temperature rise, protecting equipment from overheating. The 3/8" x 2-7/8" copper bulb provides rapid thermal response times, while the totally enclosed Micro Switch snap-acting switches offer reliable performance under demanding field conditions. Contractors will appreciate the flexible horizontal or vertical mounting options and the visible control scale with an external adjustment screw for simplified calibration. Whether you are performing a new install or replacing an existing Honeywell L4006E1042, this controller integrates seamlessly with standard immersion wells to maintain peak boiler temperature control and system efficiency.
Key Benefits- Manual Reset Safety: Prevents automatic system restarts after a high-limit trip, ensuring a technician can inspect for underlying issues.
- Flexible Orientation: Designed for both horizontal and vertical mounting to accommodate tight mechanical room piping.
- Industrial Build: Features a totally enclosed Micro Switch to prevent dust and moisture interference with contact reliability.
- Accurate Sensing: The liquid-filled copper bulb ensures highly sensitive thermal conductivity for precise liquid temperature monitoring.
- Broad Application: Suitable for regulating high-temperature limits in hydronic heating, storage tanks, and duct air applications.
What is the purpose of the manual reset on the L4006E1042?
The manual reset serves as a safety lockout. If the boiler or tank liquid hits the high-limit setpoint, the SPST contacts break to shut down the burner or heat source. The system will not restart until a technician manually pushes the reset button, allowing for a safety check of the system's operating conditions.
Can this aquastat be mounted in any position?
Yes, this model is specifically designed for horizontal or vertical insertion of the sensing element, providing flexibility when working with various boiler manifolds and storage tank configurations.
Does this unit include the immersion well?
This specific model is typically intended for use with existing wells. It is compatible with standard Honeywell / Resideo immersion wells, making it an ideal choice for service replacements where the well is already piped into the system.
