Resideo AT88A1005 Transformer 328140-751 to ensure the system remainsThe Resideo AT88A1005 is a heavy duty, foot mounted HVAC control transformer designed to deliver reliable 24V power to high demand commercial and residential systems. Engineered as a 75VA transformer, this unit effectively steps down 120V primary voltage to a stable 26. 5V secondary output, providing the extra capacity needed for complex multi stage systems or zones. The internally fused secondary provides critical overload protection, preventing
