Resideo L4006A1678 Aquastat Controller
The Resideo L4006A1678 Aquastat Controller is a professional-grade immersion sensing device engineered for high-limit or low-limit temperature control in hydronic heating systems. This immersion controller features SPST contacts designed to break on temperature rise, making it a critical component for regulating boiler water temperatures or protecting storage tanks from overheating. Equipped with a 3/8" x 2 7/8" copper bulb and a 3-inch capillary, the L4006A1678 ensures rapid thermal response and accurate sensing within an operating range of 100°F to 240°F. The adjustable differential, spanning 5°F to 30°F, allows technicians to fine-tune system cycling to prevent short-cycling and improve overall efficiency. Built to exceed standard HVAC temperature controller requirements, it includes a factory-set stop at 240°F and is the direct replacement for the 80160251. This unit supports both horizontal and vertical mounting orientations, providing flexibility for tight boiler room installations and diverse manifold configurations.
Key Benefits for the Contractor- Universal Mounting: Designed for either vertical or horizontal installation, facilitating easier retrofits in various piping layouts.
- Precise Differential Control: The adjustable 5°F to 30°F (3°C to 17°C) differential allows for optimized burner or pump performance.
- Direct Compatibility: Functionally replaces the 80160251 aquastat, ensuring seamless integration with existing hydronic system wiring.
- Enhanced Heat Transfer: Includes heat conductive compound to ensure maximum thermal contact between the bulb and the immersion well.
- Robust Electrical Ratings: Rated for 8A at 120 Vac and 5.1A at 240 Vac, suitable for standard boiler temperature limit applications.
Is the immersion well included with the L4006A1678?
This model is typically supplied as the controller and bulb assembly; if the existing well is damaged or a different depth is required, a compatible Honeywell immersion well must be sourced separately.
Can this be used as a high limit and low limit simultaneously?
No, this is an SPST device that breaks on temperature rise. It is designed to function as either a high limit or a low limit regulation control depending on how it is wired into the system, but not both at once.
What is the purpose of the heat conductive compound?
The included compound is essential for eliminating air gaps between the copper sensing bulb and the well, preventing lagged response times and ensuring the aquastat sensor reflects the actual liquid temperature accurately.
