Carrier HH57ZC001 Enthalpy Sensor

Description

The Carrier HH57ZC001 is an enthalpy sensor engineered for use with Carrier HVAC systems, providing accurate measurement of outdoor air enthalpy to optimize economizer operation and improve overall system efficiency.

Overview

Enthalpy sensors play a critical role in building automation and economizer control strategies. By measuring the heat content (enthalpy) of outdoor air — a combination of temperature and humidity — the HH57ZC001 enables the HVAC system to determine when it is energy-efficient to use outside air for free cooling versus recirculating return air. This helps reduce mechanical cooling loads and lowers energy consumption.

Key Features

• Designed for use with Carrier HVAC equipment and compatible economizer controls
• Measures outdoor air enthalpy (combined temperature and humidity) for intelligent economizer decision-making
• Supports free-cooling strategies to reduce compressor runtime and energy costs
• Genuine Carrier OEM replacement part — ensures proper fit and reliable performance
• Durable construction suited for outdoor installation environments

Applications

• Carrier rooftop units and air handling units with economizer control
• Commercial HVAC systems utilizing differential enthalpy or single enthalpy economizer strategies
• Building automation systems requiring outdoor air quality and enthalpy monitoring
