Description
Trane CNT3603 SPDT Pressure Control Open -0.07” WC is a switch made for use simply in HVAC systems. It is an SPDT pressure control; this means it has two output contacts that respond in a typical manner Each time a sensed pressure change occurs. Here the switch opens the circuit when the pressure drops to less than – 0.07 inches Water Column (In WC). These pressure controls are critically essentialin controlling the airflow in HVAC equipment. Through mounting pressure values and triggering specific reception or application of circuits, they facilitate the functional performance of the system. Perhaps they might be applied to regulate dampers meant for controlling the flow of air based on pressure inside the ducts.
