Carrier HF660007 Enthalpy Control 319847-401 significantly reducing heating and cooling

significantly reducing heating and cooling loads by preventing over-ventilation

Selecting a genuine Aaon part ensures perfect heat wheel motor alignment and reduces vibration and noise within the air handling unit

while the relay coil requires a 24 VAC/DC source for operation

this unit handles dampers up to approximately 4 to 5 square feet

and precision-machined internal components suitable for air

Carrier HF660007 Enthalpy Control 319847-401 significantly reducing heating and coolingThe 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
