Carrier HH57AC078 Enthalpy Sensor

The Carrier HH57AC078 is an enthalpy sensor designed for installation in Carrier HVAC equipment. An enthalpy sensor is not just like a thermostat that measures temperature only, it does more than that. It measures also the temperature and relative humidity of the air, which provides a clearer understanding of the IAQ. Combined, or enthalpy, this data is essential for the HVAC system so to maintain comfortable conditions through control of both heat and cool and moisture. For instance, under hot and humid weather, the sensor identifies high enthalpy and instructs the air conditioner to not only cool the air but also dehumidify it to make it feel less sticky.
