Resideo L4006B1155 Aquastat Controller
Professional-grade boiler maintenance requires precise thermal regulation, and the Resideo L4006B1155 is a staple for hydronic circulator control. This immersion-type aquastat controller is engineered to break SPST contacts upon temperature rise, making it an essential high-limit or regulating device for boilers and storage tanks. Featuring a highly sensitive 3/8" x 2 7/8" copper bulb and a 3" capillary, this immersion aquastat ensures rapid response to liquid temperature shifts. The unit operates across a broad 100-240°F range with an adjustable differential of 5-30°F, allowing contractors to fine-tune system cycling and prevent short-cycling. Built for versatile field installation, the Honeywell L4006B1155 supports both horizontal and vertical mounting to accommodate existing immersion wells. With a factory-set safety stop at 240°F and a clearly visible control scale, this temperature limit control provides the reliable mechanical switching required in demanding mechanical rooms.
Key Benefits for Technicians- Broad Compatibility: Fits standard immersion wells, making it the preferred boiler temperature control replacement for legacy systems.
- Durability: Features a totally enclosed Micro Switch snap-acting mechanism for reliable performance in high-ambient environments up to 150°F.
- Versatile Mounting: Design allows for horizontal or vertical mounting, providing flexibility in tight piping configurations.
- Precision Tuning: The 5°F to 30°F adjustable differential helps optimize system efficiency and prevent unnecessary equipment wear.
Is the immersion well included with the L4006B1155?
No, this specific model is designed for applications that utilize an existing well. If a new well is required, it must be sourced separately.
Can this be used for low-limit applications?
Since the SPST contacts break on temperature rise, this model is primarily used as a high-limit or circulator controller. For applications requiring contacts to make on temperature rise, verify your wiring and switching requirements.
What are the electrical ratings for this controller?
The snap-acting switch is rated for 8A at 120VAC and 5.1A at 240VAC under full load conditions, suitable for most residential and light commercial circulator pumps.
