| The Carrier HH57AC078 is an enthalpy sensor intended for use in Carrier HVAC equipment. An enthalpy sensor does more than only measure temperature, like a thermostat. It measures both air temperature and humidity, giving a more complete picture of indoor air quality. This combined data, known as enthalpy, is critical for the HVAC system to maintain optimal comfort levels by controlling temperature and humidity. For example, under hot and humid weather, the sensor detects excessive enthalpy levels, telling the air conditioner to remove not only heat but also excess moisture for a more balanced and comfortable feel. |
