OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model PGACCY48HG480167

This is the genuine OEM Carrier factory-replacement DCV Economizer Control Board Kit (HH63AW001) for the Carrier PGACCY48HG480167 packaged rooftop unit. The economizer control board is the command center for your unit's demand-controlled ventilation (DCV) economizer system — it continuously monitors outdoor air conditions and CO₂/enthalpy sensors to regulate the damper actuator, blend indoor and outdoor air intelligently, and minimize mechanical cooling load. When this board fails, symptoms include a stuck-open or stuck-closed damper, fault codes on the rooftop controller, complete economizer lockout, or erratic outside-air percentages that cause energy waste and indoor air quality complaints.
