Resideo L4080B1352 Aquastat Controller
The Resideo L4080B1352 Aquastat Controller is a high-limit immersion protective device designed specifically for hydronic heating systems. As a veteran-grade boiler control, this unit triggers a break in the electrical circuit upon a temperature rise to the setpoint, preventing overheating by shutting down the burner. It features a technical operating range of 100°F to 200°F (38°C to 93°C) with a fixed 8°F (4.4°C) differential to ensure stable cycling. This immersion aquastat includes a 3-inch insertion depth and is versatile for field applications, mounting via 1/4" NPT female threads or directly to a surface through the base case. The L4080B1352 is vital for contractors managing high limit protection in line voltage or low voltage systems. Equipped with a diaphragm-actuated snap switch and a siphon loop, it provides reliable mechanical response in closed-loop boiler environments without the need for constant recalibration in the field.
Key Benefits- High Limit Precision: The liquid-filled sensing element expands reliably, using a snap-acting switch to break contact exactly at your 100-200°F setpoint.
- Versatile Mounting: Supports both 3-inch immersion well insertion or surface mounting, accommodating various insulation depths from 1 1/2" to 3".
- System Security: Integrates a factory-set stop to prevent accidental high-range adjustments by end-users, maintaining safe operating parameters.
- Durable Construction: Built with a totally enclosed Micro Switch for longevity in high-heat mechanical rooms and demanding boiler applications.
Does this unit include the immersion well?
No, this model is typically provided "less well." You will need to utilize an existing compatible well or source the correct 1/2" or 3/4" NPT well for new installations.
Can I use this for low-voltage millivolt systems?
Yes, the L4080B1352 is rated for millivolt applications (0.25 A @ 0.25 to 12 Vdc) as well as standard 120V and 240V circuits, making it a flexible boiler temperature controller for your truck stock.
Is the temperature differential adjustable?
This specific model features a fixed 8°F differential. If your application requires a wide or narrow adjustable differential, you should verify the specific requirements of the hydronic loop before installation.
