Honyewell L4008A1015 Temperature Control

Honyewell L4008A1015 Temperature Control

The Honeywell L4008A1015 is a professional-grade remote bulb immersion type temperature control designed for precise regulation of boiler water temperatures in hydronic heating systems. Functioning as a high or low limit controller, this SPST (Single Pole Single Throw) device features contacts that break on temperature rise, ensuring critical system protection. With an operating temperature range of 100°F to 240°F and an adjustable differential of 5°F to 30°F, it provides the versatility needed for various aquastat controller applications. The unit includes a 5-1/2 foot capillary length, allowing for flexible remote sensing, and supports both horizontal and vertical mounting configurations. This model is technically identical to the L4008A1015/U. When performing a Honeywell L4008A1015 replacement, ensure the immersion well matches the 3/8 inch x 2-7/8 inch bulb dimensions for optimal thermal transfer and response accuracy.

Key Benefits for the Contractor
  • Versatile Application: Functions effectively as either a high-limit or low-limit control in commercial and residential hydronic systems.
  • Flexible Installation: Remote bulb sensing and multi-position mounting allow for placement in tight mechanical rooms where direct-mount controls won't fit.
  • Reliable Switching: High-quality SPST snap-action switches provide consistent performance under a wide range of electrical loads.
  • Field Adjustable: The 5-30 degree differential allows technicians to fine-tune burner cycles for improved efficiency and reduced equipment wear.
Common Questions & Technical Insights

What is the difference between the L4008A1015 and the L4008A1015/U?
There is no functional or technical difference between these two part numbers; the "U" suffix simply denotes a universal retail-packaged version of the same industrial controller.

Can this unit be used for cooling applications?
No, this specific model is designed to break the circuit on a temperature rise, making it suitable for heating limits. For cooling or "make-on-rise" requirements, a different model in the L4008 series would be required.

Does this include the immersion well?
Standard L4008A models often require a separate immersion well if one is not already present in the piping or boiler tapping. Always verify the bulb dimensions (3/8" x 2-7/8") against your existing well to ensure proper fitment.
