Carrier HF660007 Enthalpy Control 319847-401 variable speed motors require specificThe Carrier HF660007 Enthalpy Control with integrated sensor is the direct OEM replacement for the obsolete HH57AC077. Engineered for 24 VAC commercial economizer systems, this high precision HVAG enthalpy controller monitors both latent and sensible heat to optimize outside air intake. By calculating the total heat content of the air rather than just dry bulb temperature, the HF660007 ensures the economizer only utilizes outdoor air when it is truly
