Resideo L4008E1313 Control

The Resideo L4008E1313 is a professional-grade remote bulb immersion type temperature control designed for high-limit safety applications in hydronic heating systems. Engineered for precision, this aquastat controller features a single pole single throw (SPST) micro-switch mechanism where the contacts break on temperature rise, ensuring system protection when temperatures exceed safely defined thresholds. This model operates within a critical 100-200 degree Fahrenheit range and requires a manual reset, a vital feature for technicians needing to verify system integrity before restoring operation. The 5 1/2' capillary length provides sufficient reach for flexible installation, while the remote bulb accurately senses liquid temperatures in boilers or storage tanks. This high limit aquastat supports both horizontal or vertical mounting, allowing it to integrate seamlessly into diverse mechanical room configurations. Rely on this remote bulb temperature controller to maintain strict thermal regulation and prevent hazardous over-temperature conditions in demanding residential and commercial HVACR environments.

• Enhanced System Safety: The manual reset requirement ensures that a technician must inspect the installation after a high-limit event before the system can restart.
• Precise Sensing: A highly responsive remote bulb element detects rapid temperature changes in boilers and tanks for immediate high-limit protection.
• Installation Versatility: Dual-orientation mounting (horizontal or vertical) and a 5.5-foot capillary accommodate various piping and tank geometries.
• Durable Construction: Features a totally enclosed snap-acting switch to prevent dust and moisture interference in tough mechanical environments.

Common Questions

What is the maximum ambient temperature for this controller?
The L4008E1313 is designed to operate in ambient temperatures up to 150°F (66°C) at the case location.

Can this be used for low-limit control?
While this specific model is calibrated for high-limit applications where contacts break on rise, it is essential to use the correct model number for low-limit functions to ensure the proper switching action for your sequence of operation.

What electrical loads is the SPST switch rated for?
This controller typically supports 8A at 120VAC and 5.1A at 240VAC full load, making it suitable for direct control of small motors or as a pilot duty device for a larger contactor.
