Carrier HF660006 Economizer Retrofit Kit

The Carrier HF660006 Economizer Retrofit Kit that can be used to improve the efficiency of Carrier HVAC systems that are already installed. Economists utilize cooler outdoor air during the mild seasons of the year to minimize the use of mechanical cooling. This kit combines all the required parts to provide this functionality. At some outside temperatures, the economizer brings fresh cool air into the building and thus reduces the load on the air conditioning unit. This is in essence a lower power requirement and possibly lower cooling costs. It works at a low voltage of 20-30 volts and is suitable for 60 Hz systems of electrical power.
