The Carrier HH23AG085 is a high-precision OEM temperature control engineered for critical thermal regulation in Carrier, Bryant, and Payne HVAC systems. This heavy-duty controller features a 20-foot capillary tube, providing technicians with the necessary reach for remote sensing in complex commercial or residential internal cabinet configurations. Designed to operate within a 15°F to 90°F temperature range, it serves as a primary refrigeration limit switch or ambient temperature sensor to ensure the compressor and fan cycles maintain optimal setpoints without drifting. As a genuine Carrier replacement part, the HH23AG085 is factory-tested to meet exact sensing tolerances, preventing the premature wear often associated with aftermarket "universal" controls. Whether you are servicing a rooftop unit or a specialized air handler, this HVAC temperature controller provides the reliability required for 24/7 climate monitoring. Utilizing authentic Carrier HVAC parts ensures seamless integration with existing wiring harnesses and control boards, maintaining the system's original engineering specifications and performance efficiency.

• Broad Sensing Range: Operates between 15°F and 90°F, making it versatile for both heating and cooling limit applications.
• Extended Reach: The 20' capillary allows for flexible sensor placement far from the control mounting point.
• Exact OEM Fit: Guaranteed compatibility with Carrier HH23AG085 specifications for Bryant and Payne equipment.
• Industrial Durability: Built to withstand the high-vibration environment of HVAC cabinets and mechanical rooms.

What is the primary function of the 20' capillary lead?
The extended capillary allows the sensing bulb to be positioned in the optimal airflow or refrigerant line path while the control body remains accessible in the electrical section.

Can this part replace mechanical thermostats in older Carrier units?
This is an OEM part designed for specific system logic; always verify your model number to ensure this control's 15/90F range matches your existing component's setpoints.

Is the HH23AG085 compatible with R-410A systems?
Yes, as a temperature-based control, it is compatible with various refrigerant platforms, provided the application falls within its rated temperature and electrical specifications.
