Description
When your HVAC or packaged rooftop unit’s economizer or outdoor air logic isn’t performing correctly, the Carrier HH57AC080 outside air sensor provides a reliable OEM grade replacement. This sensor measures the outside air dry bulb temperature (or in some configurations is used for enthalpy/free cooling control) and enables the system to optimize outdoor air usage, guard against improper damper positions, and support energy efficient operation.
Key Features
- Authentic OEM Quality: This is a factory authorized Carrier sensor, engineered to meet the original design specifications and maintain system performance.
- Accurate Outdoor Air Measurement: Designed for use in economizer and outdoor air control applications; helps determine when free cooling is permissible or when dampers should be modulated.
- Drop In Replacement: For units that specify part number HH57AC080, this sensor fits the existing mount and wiring without the need for major modifications.
- Wide Application Range: Suitable for commercial packaged units, rooftop HVAC systems, and other air handling equipment that rely on outdoor air temperature sensing.
- Improves Energy Efficiency: By restoring proper outdoor air sensing and economizer function, the sensor helps reduce unnecessary mechanical cooling and optimize damper operation.
