Resideo L4006A1009 Aquastat Controller
The Resideo L4006A1009 Aquastat Controller is a professional-grade immersion temperature controller designed for precise regulation in hydronic heating systems, storage tanks, and boilers. This high or low limit aquastat utilizes a 3/8" x 2 7/8" copper sensing bulb to monitor liquid temperatures between 100°F and 240°F. Featuring internal SPST contacts that break on temperature rise, this unit is engineered for reliable safety shut-off or cycling applications. The L4006A1009 includes a 5°F fixed differential, ensuring tight control cycles and preventing excessive equipment short-cycling. Technicians appreciate the flexibility of the horizontal or vertical mounting positions and the inclusion of a 1/2" NPT well spud for standard boiler tappings. The totally enclosed Micro Switch snap-acting design protects internal components from dust and debris, while the visible control point scale allows for quick field adjustments without specialized tools.
Key Benefits:- Versatile Application: Functions as either a high limit safety or low limit regulator to maintain minimum boiler temperatures for domestic hot water.
- Flexible Installation: Universal mounting design supports both vertical and horizontal sensor insertion into existing or provided wells.
- Enhanced Durability: Equipped with a totally enclosed Micro Switch snap-acting mechanism for reliable performance in demanding mechanical rooms.
- Precise Sensing: 3/8" copper bulb provides rapid thermal response to liquid temperature fluctuations.
- Standard Compatibility: 1/2" NPT well spud fits most standard hydronic equipment and storage tank ports.
- Can this be used for both high and low limit applications? Yes, the Resideo L4006A1009 is a universal immersion type device suitable for either limit depending on system wiring.
- What does "break on temperature rise" mean for my system? In this configuration, the SPST contacts will open (cutting power to the burner or circulator) once the temperature reaches the setpoint minus the differential.
- Is the immersion well included with this model? Most L4006A1009 TRADELINE models include the 1/2" NPT well, though it is designed to work with most existing wells that accommodate a 3/8" bulb.
