Description
The York S1-024-35707-000 SPNO Pressure Switch is used for HVAC systems. This switch is used to detect air pressure within the HVAC ductwork and it operates at a low-pressure range of 0.20” WC. When the pressure gets below this setpoint, the switch opens, and a response occurs. This response may be turning off a machine to avoid it being damaged, sounding a bell to notify maintenance personnel or running a program that will change the pressure. This switch plays a role of enhancing the efficiency of the system, avoiding frequent repairs resulting from inadequate airflow and enhancing comfort of the occupants
