Resideo L4006E1117 Aquastat Controller
The Resideo L4006E1117 Aquastat Controller is a professional-grade high limit manual reset immersion device engineered for precision liquid temperature regulation in hydronic systems, boilers, and storage tanks. Featuring an SPST switch that reliably breaks the circuit on temperature rise, this controller is a critical safety component to prevent equipment overheating. The unit is equipped with a 3/8" x 2-7/8" copper bulb and a 1-1/2" capillary, ensuring fast thermal response times. Designed for maximum field flexibility, it supports both horizontal and vertical mounting configurations. With a broad 100-240 degree temperature range and a standard 3/4" well spud, the L4006E1117 integrates seamlessly into existing HVACR infrastructures. The manual reset feature provides an essential failsafe, requiring a technician's inspection before system reactivation, making it a staple for code-compliant boiler high limit control installations. Its totally enclosed Micro Switch snap-acting mechanism ensures long-term switching reliability under standard pilot duty or motor load demands.
Key Benefits- Critical Safety Failsafe: The manual reset function ensures the system stays offline until an HVAC technician can verify the cause of the over-temperature condition.
- Installation Versatility: Dual-mount capability (horizontal or vertical) allows for easy integration regardless of the domestic hot water or boiler tapping orientation.
- Precise Thermal Sensing: High-sensitivity copper immersion bulb facilitates accurate temperature tracking, essential for maintaining tight system tolerances.
- Rugged Electrical Design: Features a durable SPST contact system rated for 120V and 240V applications, providing stable "break on rise" performance.
Is the immersion well included with the L4006E1117?
Yes, this model typically includes a 3/4 inch NPT immersion well (model 123870A) to facilitate a secure, direct-immersion interface with the system fluid.
Can this be used as a low limit controller?
While technically feasible if paired with a separate high limit device, the L4006E1117 is specifically calibrated and intended for high limit manual reset safety applications.
What are the electrical ratings for the contacts?
The SPST switch is rated for 8.0A at 120V AC and 5.1A at 240V AC under full load, with high locked rotor capacity to handle various burner or circulator motor requirements.
