IO Hvac Controls iO-SPC Pressure Control 328140-751 Standard industry practice dictates replacementThe iO HVAC Controls iO SPC is a professional grade static pressure controller designed to manage airflow within zoned HVAC systems. Engineered with a solid state switching and timing circuit, this unit enhances system reliability by providing precise control over bypass dampers equipped with floating type actuators. As individual zone dampers modulate, the iO SPC monitors the supply plenum pressure, automatically adjusting the bypass air to maintain
