Resideo L6006A1269/B Controller

The Resideo L6006A1269/B Aquastat Controller is a high-performance immersion temperature control engineered for hydronic heating systems, storage tanks, and various liquid media applications. Utilizing a sensitive copper sensing bulb, this controller provides high-accuracy thermal feedback for precise boiler temperature regulation. This logic-switching device features a Single Pole Double Throw (SPDT) configuration, allowing a technician to wire it as a high-limit, low-limit, or circulator controller depending on the system requirements. With an adjustable temperature range of 100°F to 240°F and a fixed differential of 5°F to 30°F, it offers the flexibility needed for custom hydronic tuning. Designed for horizontal insertion via an immersion well, the L6006A1269/B facilitates seamless integration into existing residential boiler controls, ensuring consistent thermal management and preventing overheat conditions in domestic hot water and space heating loops.

Key Benefits

• Application Versatility: The SPDT switching action enables use in breaking a circuit on temperature rise (high limit) or making a circuit on temperature rise (circulator or low limit control).
• Precise Calibration: Large, accessible control point scale allowing for easy field adjustments to meet specific HVAC hydronic system setpoints.
• Durable Construction: Built to withstand commercial and residential environments with UL-recognized and CSA-certified electrical ratings.
• Fast Thermal Response: The liquid-filled sensing element ensures rapid detection of temperature fluctuations for tight system control.

Common Questions

Can the L6006A1269/B be used as a replacement for an L4006A?
Yes, in many applications the L6006 series can replace L4006 or L6006 models, provided the immersion well depth and technical specifications align. Always verify the required bulb length and differential before installation.

Does this unit include the immersion well?
The L6006A1269/B is typically designed for use with a standard 1/2 inch or 3/4 inch NPT immersion well. Check your existing well depth to ensure the copper sensing bulb has full contact for accurate heat transfer.

How do I wire this for circulator control?
For circulator controller operation, wire to the terminals that make the circuit on a temperature rise, ensuring the pump only activates once the boiler water has reached the minimum operating temperature.
